What is included in 925 silver

925 sterling silver - what is it?

Regardless of where we purchase jewelry, in a regular jewelry store or by ordering online, we have a question: is the real precious metal used to produce it?

If in a jewelry store we can hold the jewelry in our hands, then when making a purchase in the online store http://cerena-silver.ru we are guided by the marking or hallmark indicated on it.

Recently, jewelry made from silver has come back into fashion. They come in different hallmarks, such as 800, 830, 925. The most common is 925 sterling silver. Let's figure out what this test means.

Compound

925 standard shows that this alloy contains 92.5% silver and 7.5% other metals. The larger the sample size, the more silver and less additional metals the product contains. 925 silver is the highest standard used to create jewelry.

Additional metals that can be used are:

• copper;
• silicon;
• zinc;
• germanium;
• platinum.

The most popular alloy is silver and copper. Very often, such silver is also called “sterling”. Sterling silver is very popular not only among manufacturers and sellers, but also among customers. Jewelry made from this metal is beautiful, high quality and durable.

Why are other metals added to silver?

Silver is a very soft and fragile metal and in its pure form is used only for industrial purposes. Jewelry is not made from it. If the jewelry shows 999 purity, it’s a lie!

Other metals are added to 925 silver in order to:

• give strength to jewelry;
• maintain the intricate shape of jewelry;
• chains, pendants, rings and other accessories did not turn black and dull, but retained their natural noble shine;
• the product was not damaged during use. This is especially true for silver cutlery.

Coating

Very often, silver jewelry is treated with a special coating. It is used to prevent the product from corroding and deteriorating over time, and also to give the silver accessory a different shade.

The most popular silver coatings: - rhodium plated - gives jewelry a bright, noble white color;

— oxidized or blackened silver will appeal to connoisseurs of antiquities and antiques. It can be either completely black or contain individual elements of a black shade.

925 sterling silver jewelry is a stylish and fashionable accessory that will add elegance and sophistication to your look.

Composition of 925 silver, characteristics and features of products

Jewelry made from precious metals is always in demand. Metals for jewelry are not used in their pure form. Gold and silver are soft metals; in the jewelry industry they are strengthened with alloys or special impurities. 925 silver is of the highest quality. It consists of 92% pure metal.

Silver is a versatile metal used in medicine, industry and jewelry. In its pure form it is plastic and easy to process. The strength of silver products is given by the addition of copper or other chemical elements.

The composition of 925 silver may include:

• Zinc,
• Silicon,
• Germanium,
• Platinum,
• Copper.

The composition of a metal affects its physical properties. The product changes color depending on the composition. The main task of jewelers is to protect jewelry from oxidation. The best alloy for 925 silver is copper.

One of the main advantages of silver is its beautiful appearance and low cost.

In Russia it is customary to distinguish the following samples:

The sample shows how many percent of pure metal is contained in the alloy.

925 silver is considered to be an elite metal. The second name for the alloy is sterling silver. The appearance of this alloy is no different from pure metal. Pure silver bends and loses its shape over time. The alloys contained in the sample give the product strength and protection from mechanical damage.

A large number of people try to purchase jewelry with this sample. The high quality of silver makes it popular and in demand all over the world.

Physical properties:

• Great thermal conductivity,
• Low melting point,
• Good electrical conductivity.

Chemical properties:

• Metal inertia.
• Reacts easily with other metals.
• Dissolves in sulfuric and nitric acid.

Silver plate

Silver cutlery has always been prized. 925 alloy is practical. Cutlery retains its attractive appearance for a long time and does not oxidize upon contact with food. The devices have bactericidal properties. If you put a silver spoon in water, it will be cleansed of pathogenic bacteria.

Previously, it was believed that silver devices could protect against evil spirits and negative energy.

Storage and care

Silver items should be stored in a dry, dark place. Sun rays hitting jewelry make it dull.

Silver items darken over time and become covered with a dark coating. You can restore the shine to your product at home. The most effective way: soak the decoration for 10 minutes in a solution of baking soda at the rate of 1.5 tablespoons per 500 ml of water. Then wipe with a soft cloth.

Ammonia is the second most effective cleaning solution. For 1 liter of water take 2 tablespoons of ammonia. It is necessary to immerse the products in the solution for 15 minutes. Cleaning at home can damage your decoration.

Dishwashing detergent can also make your jewelry look beautiful again. To do this, wash the product with a drop of the product, then rinse it with running water and wipe with a dry cloth.

Jewelry salons provide professional care for jewelry. You can take the product for cleaning or buy special solutions and wipes.

Silver hallmark

Jewelry made of precious metals must be marked with special markings. 925 sterling silver hallmark includes:

1. Label. A document that is attached to jewelry using a thread and a seal.
2. Manufacturer's mark. It has a single outline and four capital letters.
3. State stamp. This test is performed by the state inspection. Looks like a mechanical print or laser engraving.

Jewelry made from precious metals is often counterfeited. You need to choose products carefully, following simple rules:

• Buy only in official stores.
• Check the label and sample.
• When purchasing, take a cash receipt.

Fraudsters are selling silver items under the guise of white gold. Externally, the two alloys are very similar. You need to be careful when purchasing.

How to determine authenticity

If you have doubts about the authenticity of the product, you can check it at home:

• Pass the decoration along a sheet of paper. Silver jewelry will leave streaks.
• Draw a thin line of iodine with a needle. If iodine leaves yellow spots, the product is real. A white coating indicates a fake.
• Silver heats up quickly. If you immerse the product in hot water for a few seconds and then remove it with tweezers, it will be the same temperature as the water in the glass.
• Genuine jewelry is not magnetic.
• You can run chalk over the surface of the product. If the chalk becomes dark, the decoration is genuine.

There are no fakes in official stores. When purchasing, you need to pay attention to the reputation of the store. The low price of the product should also alert the buyer.

925 sterling silver: features, where it is used, cost

Jewelry made from precious metals will always remain at the peak of popularity. This is due not only to their attractive appearance, but also to increased wear resistance, corrosion resistance and the ability to maintain their original properties over a long period of time.

Such products are also attractive from a financial point of view and become excellent investment objects due to their constantly rising prices.

It is no secret that craftsmen do not use gold or silver in their pure natural form in the manufacture of jewelry, since the too soft texture of the metals creates certain difficulties in the work.

To impart hardness in industry, they are strengthened with the help of various impurities. This is how alloys are obtained, which are subsequently used to make jewelry.

In order to determine what role gold or silver plays in the alloy, markings called assays were invented, reflecting the amount of metal in grams contained in one kilogram of the alloy.

And today, most people continue to ask the pressing question: what metal content does 925 standard indicate: gold or silver?

Sample 925: what is it?

This test very often causes numerous debates among those who know practically nothing about precious metals or have a superficial understanding of them. The subject of the dispute is always the same: silver products, like gold jewelry, are marked 925.

How then to distinguish these two metals? First of all, you need to understand the basic testing systems. In Russia and the CIS countries, gold is marked with the following hallmarks:

• 375: a shade of red that turns to gray after the top polish comes off the product;
• 583: The alloy contains copper, so the color is most often reddish;
• 585: the most common and ranging from red or pink to yellow and white:
• 750: includes copper and silver in the alloy;
• 958: Almost pure gold of a bright yellow color.

There is also a 999 standard, but this is the metal in its purest form, and it is practically not used in the production of jewelry.

As for silver, its samples in the Russian Federation are as follows:

Consequently, 925 silver shows that the alloy contains 92.5% pure metal, the rest comes from other components.

Thus, the hallmark marked 925 is typical only for silver. It is impossible to find gold jewelry with this marking due to its absence in the generally accepted list.

Although theory suggests that the presence of 925 noble metal is acceptable. However, international standards contradict this opinion, since such markings are inherent in the metal being too soft, as a result of which its use in the jewelry industry is inappropriate.

Fraudsters often try to pass off silver of this standard as gold. And this is not surprising, since the price per gram of the noble metal is much higher.

To obtain real white gold, several methods are used:

• adding palladium or platinum to the alloy;
• applying radium to the surface of the decoration, the price of which is much higher than the cost of gold.

Nevertheless, gold-plated silver continues to be passed off as gold by unscrupulous manufacturers, guaranteeing them excellent income.

What are the features of 925 silver?

Another name for this type of silver is coin or sterling. It is characterized by a dazzling white color and high strength.

The history of the alloy goes back to the 12th century. At that time, coins of this standard of silver were produced in Germany. The next state to take advantage of this experience was England.

Such silver is much stronger than gold. Due to this feature, it is often used to make jewelry decorated with precious stones. Main areas of use: jewelry industry, production of coins and souvenirs.

Despite its strength, jewelers highly value 925 metal. It is flexible to work with and provides ample opportunities for the production of the most sophisticated jewelry.

The silver alloy differs from the gold ligature. As a rule, it includes silicon, germanium, and platinum. They strengthen the strength and give the desired shade to the finished ingots.

925 silver contains 92.5% pure metal, the remaining 7.5% is allocated to various impurities. This marking is more common among jewelers than others, since other samples oxidize and darken faster.

This metal is also treated with silver plating. This provides additional brightness, shine and protection from external damage.

In addition, the 925 alloy is coated with sulfur. The result is silver, called oxidized. From the outside it looks like an antique. But the color qualities only benefit from this.

The next stage is coating the product with an oxide film and control polishing. Thus, the concave parts acquire a darker shade, and the convex elements become lighter. Such jewelry is easy to care for and does not require frequent and regular cleaning.

Therefore, 925 is the standard marking for the precious metal. Disagreements can only arise when choosing gold-plated products, since they are not branded.

Where is 925 silver used?

In addition to the jewelry industry, 925 sterling silver is widely used in the production of cutlery and tableware.

Metal objects with such markings do not lose their shape for a long time, do not oxidize, and perfectly withstand contact with food at any temperature.

The ability of silver to stretch provides ample opportunities for the imagination of jewelry craftsmen in making unique lightweight jewelry (rings, earrings, chains and bracelets).

How much does 925 metal cost?

The price per gram of silver is determined by several factors:

• payment for the work of the master;
• transport and customs costs (in case of import into the country);
• taxation;
• seller's income;
• brand awareness. Very often, silver items from famous manufacturers cost much more than gold jewelry of the same weight and quality from a little-known master.

To determine the cost, the accounting price is multiplied by a factor of 0.925. The discount price is set by the Central Bank of the Russian Federation for all metals of precious origin every day at 15:00 Moscow time.

The next day, the information received is used in financial and credit organizations and accounting.

The prices used for purchase and sale relationships are determined at the market average level. Since such transactions are associated with monetary risks. For them, it is necessary to take into account market conditions.

The cost of one gram of 925 silver in different jewelry varies from 40 to 100 rubles. This is influenced by the popularity of the manufacturer, industrial technology, complexity and quality of decoration.

Externally, the brightness and shine of white gold is more expressive than that of silver products. However, modern technologies, through which metal is irradiated and other components are deposited on its surface, have come far ahead.

This provides great opportunities for illegal activities by jewelry fraudsters. Therefore, in order not to become an object of deception, at the slightest doubt you should contact professional appraisers and insist on laboratory testing of the product using special equipment and tools.

Sterling Silver

Silver is one of the noble, expensive metals that has been familiar to the human race since ancient times, which has many confirmations that have survived to this day and were found during various archaeological and historical research.

Previously, silver could only be mined as nuggets, but with the development of technology and technology, the extraction of silver-containing ores and the extraction of silver directly from them began to be carried out using machines, mechanisms and on an industrial scale.

The use of silver in modern life is quite widespread; silver chains are especially popular, which, at their cost, can be easily afforded by people with very modest incomes.

Jewelry craftsmen use silver to make coins, cutlery, orders and medals, and jewelry. 925 silver is used for such things , in which the content of the main precious metal is at least 92.5 percent.

In some of its physical characteristics, silver compares favorably with gold. It is heavier, harder, stronger.

From an aesthetic point of view, some cut precious and semi-precious stones set in 925 silver “play” and reveal themselves better than when processed in gold.

Only over time, such silver jewelry, to the great regret of its owners, loses its noble shine and color due to high humidity and interaction with aggressive compounds in the surrounding air. But with all this, the life of the product is directly related to the fineness of the noble metal: as you know, the higher the fineness, the less susceptible the jewelry is to the influence of external factors. In this regard, silver compares favorably with its less high-grade “brothers.”

Which is better, gold or silver?

There are ongoing debates in the world community about which jewelry is better - silver or gold. Each of these precious metals has many fans. Historically, jewelers have valued silver less than gold, and physicists and chemists around the world have noted the superiority of silver in its properties. And global fashion trends in jewelry are very changeable and give the palm to jewelry made of silver or gold.

From silver, a professional and expert in his field is quite capable of making such an exclusive piece of jewelry, striking the imagination with the beauty of its lines, the subtlety and filigree of its decoration, and inclusions or inserts of stones and enamel, that gold is not required.

And the price of the jewelry can be so high that gold items can lie aside. 925 silver is especially good at highlighting the color and shine of amber and pearls in jewelry.

But silver is also widely used as an additional element - in compositions of several noble metals in the form of inserts, overlays and other things.

And finally, precious items made from 925 sterling silver , no matter how massive and heavy they are, do not evoke a feeling of excess and intrusiveness. Silver jewelry items cannot look vulgar by definition and allow you to add fullness and completeness to the chosen style and are considered ideal for all individuals, regardless of their age, gender and social status in society.

Silver cleaning

Preventing tarnishing of silver items involves wiping the item monthly with a flannel, suede cloth or felt..

The use of abrasive materials is strictly not recommended, because they can damage the surface of the metal, and in the future it can only be cleaned by polishing, often exclusively in jewelry workshops.

To do this, the silver item is first soaked in soapy water, thoroughly rinsed, dried, and then polished with flannel or suede. You should choose non-metallic utensils for cleaning. Specialized cleaning products have also been developed for silver, which can be purchased in jewelry stores.

In addition to cleaning silver items with special products, there are also several alternative cleaning methods. Before cleaning any of them, you should soak the product in soapy water and rinse well. Let's look at several ways to clean 925 silver.

Cleaning with soda

You need to make a solution in the proportion of 50 g of soda per 1 liter of hot water. It is necessary to carefully wipe the surface of the silver object with a flannel soaked in the solution. If the contamination is very strong (blackening), you should make a paste-like solution of soda in water, and only a little water is needed. The resulting mass is carefully applied to the surface and easily polished to avoid scratches.

Cleaning with ammonia

Ammonia and chalk are mixed to form a thick porridge, applied to the object and left to dry. After the mixture has completely dried, the product must be thoroughly washed and dried. This method has an alternative option. Ammonia dissolves in water in a ratio of 1:10. The tarnished silver item is placed in the solution for 15-20 minutes, after which it must be rinsed with water and wiped with a soft flannel cloth.

Cleaning with hydrogen peroxide

Hydrogen peroxide works very well for cleaning fine gold and silver jewelry, but be aware that it reacts well with other metals. Therefore, if you do not know the alloy grade or are not sure about the alloying additive in your product, do not use this method, otherwise you may get the opposite effect.

925 silver with gemstones and pearls requires special attention. To clean jewelry with precious stones, you should try to use only special cleaning products. If this is not possible, then you can use a solution of ammonia in water in the proportion of 6 drops of alcohol per 1 glass of water.

In the case where the item is encrusted with pearls, it is better to rinse it often in a soapy solution. After rinsing, the product is wrapped in a soft linen cloth, to which you need to add 1 teaspoon of salt, and rinsed again under running water until all the salt is washed away.

Under no circumstances should such items be cleaned with ammonia; it negatively affects the color of the pearls.

925: sterling silver

Silver is one of the popular and widespread precious metals. Pure silver has a purity of 999 and is typically used for investment purposes. For the manufacture of various products, alloys of silver with other metals are chosen. The process of alloying silver makes the metal stronger and eliminates some of the disadvantages of pure argentum. One of the most famous alloys is 925 silver. Products made from such silver are sold not only in stores, but also in banks.

925 standard: alloy composition

What does 925 silver mean? The sample indicates the percentage of pure argentum in the alloy. Its share is 92.5%, the remaining 7.5% of the alloy is impurities. The composition of 925 silver most often includes copper. It is this metal that is considered the best alloy for such an alloy. Impurities affect the color of 925 silver.

925 standard is the so-called sterling silver, which is also used for making collectible coins. When alloying argentum, only one metal can be used in such an alloy. To produce such an alloy, experiments were once carried out with different types of alloys. For example, metals such as germanium, platinum, zinc, cadmium and other metals were used as additives. However, the composition of 925 silver with copper remains classic.

The fact is that impurities affect the color of silver and its properties. You can guess the metal in the alloy by checking whether 925 silver tarnishes. With copper, cadmium and platinum the alloy does not darken. When other metals are added, the problem of blackening the silver surface remains relevant.

925 silver products

Products made from 925 sterling silver are varied; the alloy is used to produce collectible coins and items, jewelry and items for interior decoration. Sterling silver has a pure white color with no tarnish. When purchasing items made from 925 sterling silver, you can find jewelry not only made from an alloy containing an admixture of copper.

Jewelry with some impurities is more expensive. This is one of the reasons why, during experiments with the alloy, copper remained the main impurity in its composition - it is a more economical metal that solves problems with darkening of products. At the same time, silver remains hard and durable, it is protected from mechanical damage and scratches. This is very important for jewelry and other alloy items.

The cost of 925 silver

You can find out how much 925 silver costs by checking the exchange rate for pure silver. Such information is provided by banks and precious metals exchanges. To determine the cost of the alloy, you need to divide the price of pure silver by 1000 and multiply by 925. This will be the cost of sterling silver.

You can also find out how much 925 silver costs in pawn shops in Moscow. Buying silver is an area where prices can be volatile and vary from one receiving location to another. Before selling, it is advisable to find out prices from several pawn shops that inspire confidence.

Selling silver

You can donate silver or pawn it at a pawnshop. First, you should find a reliable company that will offer favorable terms of the transaction. The price in a good pawnshop cannot be understated, because the office still makes its profit by increasing the price of the alloy when selling finished products and by increasing the exchange rate of silver.

It is better to hand over precious metals and products made from them to pawn shops rather than sell them to private buyers. An item from a pawnshop can still be redeemed for some period of time, but private owners will have the silver forever. By choosing a reliable pawnshop, you don’t have to worry about the integrity of the transaction.

How much does a gram of 925 silver cost in 2018-2019?

Precious metals have always been and remain the best investment for the future. Regimes, money, and the priority of currencies changed, but the demand for gold and silver clearly never fell.

Moreover, prices for precious metals in general often surprise and make you think about their relevance.

So, the price of 925 sterling silver per gram in 2019 is so different depending on the purpose of its acquisition or donation, that the consumer should understand how much 925 sterling silver costs, because it is the most common and makes up about 80% of other samples.

It is impossible to unequivocally answer the question of how much a gram of 925 silver costs, since its price is determined based on the general situation on the London exchange. And it changes daily, depending on economic indicators around the world.

925 silver price per gram in 2019

The cost of 925 silver per 1 gram depends on the method of its sale, the product and the possibility of subsequent redemption. So 925 silver, the price per gram in which is the lowest in a pawn shop, today costs about 18-21 rubles. While in purchases it ranges from 26 to 31 rubles.

This difference is due to the economic risks of the organization purchasing the precious metal. It is no secret that a clear advantage of pawnshops was and remains the possibility of subsequent repurchase of the product. Purchases do not provide such an opportunity.

And the need for pawning or selling jewelry can be different, as well as the role of this product in a person’s life. Hence the clear advantage of buying in price.

Purchasing jewelry or 925 silverware will be much more expensive for the buyer, since stores sell ready-made jewelry or other silver products at a price of about 600 rubles per 1 gram. These are the indicators of today, at a time when the price of 925 silver on the stock exchange per gram is 34 rubles 51 kopecks.

925 silver in a pawn shop costs about 18-21 rubles per gram

In specialized purchases without the possibility of redemption - 26-31 rubles. for 1 gram

In jewelry stores, jewelry costs 600 rubles and more per gram

With such a spread in prices, manipulations are currently taking place in the field of purchase and sale of precious metals. Each price is economically justified, and the consumer independently decides whether to agree to these market conditions or not. In any case, this practice takes place not only today, but also in the deep past, when the activity of buying and selling jewelry, coins and cutlery made of gold and silver was just in its infancy.

Sterling silver 925, the price per gram of which, as it turned out, consists of a number of indicators, is a fairly high and popular variety of the precious metal.

In terms of its composition and the presence of additional elements, such a product will be one of the best and most expensive even after a certain period of time.

Therefore, the feasibility of investing in precious metals has been proven for hundreds of years and still occupies a leading position among the chosen methods of storing savings.

925 sterling silver - what is it?

925 silver is one of the highest quality and is widely used in Russia abroad. The composition of the 925 silver alloy includes 92.5% pure precious metal, the remaining 7.5% is copper. This ligature was approved by a single GOST back in Soviet times. Copper imparts the required strength to the metal and significantly improves its characteristics. Less commonly, platinum is used as an additive.

Due to this expensive component, the properties of silver are improved, it acquires a snow-white color and its oxidation is significantly reduced. In modern production, palladium, which belongs to the platinum group, and cadmium can be used as an additional element. Jewelry made from an alloy containing platinum or palladium has a higher price.

Thanks to this noble metal, the jewelry becomes dazzling white, with an incredible blue cold tint.

When using 7.5% zinc as an alloy, the silver turns out cloudy, but the alloy is incredibly durable and low in price. Zinc is rarely used as an additional component, as it often causes allergic reactions.

In addition, silver jewelry is sometimes plated with rhodium, just like white gold jewelry, to add a snow-white color and shine. Another advantage of rhodium plating is the resistance of products to oxidation in air; such jewelry does not darken.

The disadvantages include the fact that rhodium wears off over time and needs to be coated again, which is very expensive.

925 standard metal is used to make jewelry, cutlery, souvenirs, commemorative medals, and table setting items. In addition, the alloy has found application in electrical engineering.

Chinese 925 silver

Often on store shelves you can find 925 silver from China, which differs from Russian metal in its low cost (from 40 to 100 rubles per gram). In terms of its composition, the alloy meets all standards, that is, the percentage of pure silver content is exactly 92.5, the rest is impurities. The difference in price is due to the divergence in the value of currencies in the Asian region. The only thing you should pay attention to are the stones.

Often in such jewelry they turn out to be non-precious, so before purchasing you need to check the quality certificate. In addition, you need to carefully consider the choice of such a product and make sure that it is not a fake. Often, unscrupulous sellers resort to various tricks.

For example, the earrings are marked 925, which is located on the clasp, and it is this that is made of real metal; everything else is a cheap alloy that only looks like silver.

Chinese costume jewelry, which is sometimes sold under the 925 marking, should be distinguished from jewelry products. As a rule, such a product contains no more than 2% pure metal. Basically it is cupronickel, which looks very similar to silver.

Italian 925 silver

Silver from Italy is considered the best in the whole world. It is distinguished not only by the highest quality, but also by complex execution techniques, uniqueness and extraordinary design. Due to this, jewelry made from this metal is highly valued in all countries. The composition of the alloy is no different from the Russian one, but its cost is slightly higher. The special secret of Italian silver is in its processing.

Craftsmen use the galvanic method of coating silver jewelry, which gives it an extraordinary cold shine, as well as excellent physical characteristics. This silver is very durable and has high anti-corrosion properties.

Thus, craftsmen use in their work the technique of galvanic silvering, when the surface of the metal is covered with the thinnest layer of pure 999 fine metal. Rhodium plating gives the jewelry a bright silver color; moreover, such products do not darken and are perfectly combined with both cubic zirconia and diamonds.

Blackening of silver adds chic and sophistication to the jewelry, and gilding gives any jewelry respectability and nobility.

Caring for 925 sterling silver items

To ensure that your jewelry does not lose its appearance, you should take proper care of it. Such jewelry must be stored in a dark and dry place. In direct sunlight, metal can not only become dull, but also darken. The exceptions are alloys with the addition of palladium and platinum, as well as rhodium-plated silver.

In order to clean a silver item, you need to wash it in water with the addition of dishwashing detergent and wipe it with a soft cloth. You can often hear advice about cleaning with toothpaste, however, this method can damage the metal surface.

A weak solution of ammonia will help clean jewelry from the sulfide film formed upon contact with air. It is enough to hold the jewelry in it for 10 minutes, rinse with water and wipe with a soft cloth. Baking soda can also be used to clean precious metal.

To do this, you need to boil 500 ml of water with 2 tablespoons of soda, put a piece of foil and silver in there. After 10 minutes you can rinse with clean water and dry.

In addition, jewelry stores offer a selection of special means for cleaning silver items, with the help of which the jewelry will always look like new and delight you with its shine.

Hallmarks of 925 silver

Many people are interested in whether the 925 standard refers to silver or gold, and whether it is good or bad when this standard is indicated on the product. Let's start with the fact that silver and gold use their own numbers. 925 is only used on silver and cannot be used on gold. Confusion can arise when a silver item is plated with gold.

The number 925 is in the sample for a reason, since that is exactly how many grams of silver are contained in a kilogram of silver alloy. The remaining 75 g comes from various impurities (most often copper).

Compared to silver of the 800th standard, products of the 875th and other lower standards, the 925th standard is considered to be of high quality. The silver alloy of this sample is characterized by high ductility and anti-corrosion properties.

It does not have the yellow tint characteristic of samples with a large amount of copper, and does not lose its original beauty over time.

Scope of application of 925 silver

To create filigree pieces, a jeweler needs an alloy with the right properties. Silver of 875, 830 and other lower standards does not have enough flexibility for this, while the 925 alloy allows you to create real jewelry masterpieces. Earrings, bracelets, chains and other jewelry are elegant and sophisticated, which is why they are very popular. They do not deform during wear and look great.

Sometimes the same products, created from silver of the same standard, differ noticeably in the brilliance and whiteness of the silver. This is due to the fact that 925 samples can be coated with a layer of white rhodium (a platinum group metal). In this way, it is possible to protect silver from scratches and other damage, as well as give it significant brightness.

However, not all fans of silver jewelry prefer excessive shine. Some people prefer slightly darkened silver, which looks more noble and natural than rhodium-plated products. This is especially true for antique products.

In addition to jewelry from silver of this standard, expensive cutlery and other products are created. These are all kinds of vases, dishes, dessert sets, sugar bowls, candlesticks, photo frames, gift sets and more. Unlike products made from lower grade silver, dishes made from 925-grade alloy almost do not oxidize when interacting with food.

What is sterling silver?

925 silver is called sterling silver, which means it is of the highest quality. According to one version, the name is associated with the craftsmen of the German Easterling family, whose silver products were famous for their excellent quality not only in Germany. At one time, Edward I awarded this family the right to mint banknotes for the country, and Henry II ordered that Easterling Silver be considered the standard for coins. Easterling was later shortened to Sterling.

Price per gram of 925 silver

925 silver is highly valued on the market, but experiences constant price fluctuations. If we take as an example the period from April 2016 to April 2017, the price per gram of 925 silver experienced jumps from 28 rubles (in January 2017) to 41 rubles (in August 2016). You can find out the cost of a gram of 925 silver from the daily report of the Central Bank of Russia.

925 silver hallmarks

Since the introduction of assay offices in Russia, sterling silver (925) was accompanied by a three-character hallmark: first there was the letter of the district that was responsible for the production of silver, then a special hallmark (an image of a woman’s head in a kokoshnik) and the number 925.

Note that by turning a woman’s head, one can determine in what period a particular silver item was created. If the head is turned to the left, then we are talking about antique products produced before 1908. Accordingly, in a later period, the head in the hallmark was turned to the right.

The presence of a star with the image of a hammer and sickle instead of a head means that the product was created in Soviet times.

925 silver (features, composition, cost)

Probably, everyone who has at least once bought products made of precious metals has come across such a concept as hallmark. It is usually expressed in certain numbers, and for jewelry alloys it is of decisive importance.

For example, if we talk specifically about silver, then, as a rule, 925 standard is used for jewelry. But what is it, what characteristics does it have and why only 925 and not, say, 895 or 1000? Well, let's look into this issue.

Let's decipher the very concept of a sample

In general, for any precious metal, fineness is perhaps the most important characteristic.
It says a lot, or rather, it gives an idea of ​​the alloy that is before us. It is known that precious metals themselves are quite fragile compared to industrial ones, therefore, in order to improve their qualities, as well as increase strength and wear resistance, other elements are added to the composition. And the percentage ratio of the jewelry element and impurities is expressed by breakdown. Now more details.

Silver, as a rule, has a mark of 925. This means that in 1 gram of the presented jewelry alloy, this metal occupies 92.5%.

That is, practically we have a pure element. Only with small inclusions.

What is added to the composition? The most common elements are: Copper (the alloy becomes yellowish or red, depending on the amount of copper, most often it is what is added); Nickel (in this case the alloy becomes much more durable); Zinc (adds ductility, very convenient for thin, fine products).

In general, it is not necessary that 925 silver contains any one component.

• 925 silver
• 925 silver
• 925 silver

Sometimes the composition turns out to be more complex. This is done, we recall, in order to improve the qualities of the noble metal, to make it more flexible and less susceptible to adverse influences during use.

After all, any piece of jewelry is worn for more than one day, and wedding rings are never removed, so such a characteristic as durability is very important. In addition, even precious metal is susceptible to oxidation. And this is another reason to add other components to it and protect it, while preserving the beauty of the product for as long as possible.

Why exactly 925?

Yes, indeed, how did it happen that this particular alloy became the most common in jewelry? This happened for several reasons.

Silver itself is more stable and stronger than gold, so fewer impurities need to be added to it. In addition, it is sufficiently resistant to the adverse effects of oxygen, which easily oxidizes other elements.

And organic acids are not dangerous for this noble metal. This is why silver is used in almost pure form.

925 silver

925 alloy is a common material for jewelry work. It is called sterling or, much more simply, standard silver. It is in this proportion that both aesthetic and operational advantages are very successfully and organically intertwined. In other words, it is 925 silver that is beautiful, durable, and resistant to various influences. And it's easy to work with him.

Initially, this alloy was used to produce English minted coins - pounds sterling. Actually, this is where this mysterious name comes from – sterling. The composition had a dazzling white color, did not darken for a very long time, and could be used for years. This was of great importance: minting money in those days was not very easy.

Then 925 silver proved itself so well that it began to be used for jewelry.

• 925 silver
• 925 silver
• 925 silver

Now this particular sample is ubiquitous in the global production of silver jewelry. The color of the products attracts with its noble shade, and the curves and smooth lines enchant. Despite the external beauty, the cost of 925 silver is not that high, but the products are often even more delicate and elegant than gold ones. In addition, many people do not like the pronounced yellowness of gold, and therefore they prefer the white metal.

In any case, silver products are no worse, and often even more noble, than any other.
So, breakdown is usually called the percentage of pure noble metal in an alloy. And they add impurities not at all to enhance the value of the decoration, but, on the contrary, to improve all its qualities.

At the same time, jewelers try to preserve the original color, but modern fashion trends, on the contrary, require experiments with color characteristics. And so yellow silver appears, which in appearance is difficult to distinguish from gold, or white gold, which can only be distinguished from silver upon careful examination. But these experiments do not affect the samples in any way, and they remain classic as before.

In the case of silver, this is the treasured mark 925. It is this that speaks of the quality of the alloy, its durability and very high aesthetic and performance characteristics. Therefore, take it boldly and don’t hesitate!

What do we know about 925 gold

The sample represents a certain standard indicating the ratio of the pure substance and the additional components of the alloy. Each of the precious metals has its own system of such standards, as well as a corresponding type of mark, which an ordinary consumer can see on the finished product.

Gold samples listed in Russia.

In the Russian Federation, the following markings are provided for yellow precious metal: 375, 500, 585, 750, 958 and 999. The 585 marking is considered the most common in use. It is characterized by good resistance to mechanical stress, wear resistance, and an affordable price.

The next in order, 750 standard, is already more expensive; it is used for products with filigree, thin drifts and for settings of fragile precious stones.

Gold of the highest grades is very soft, polishing on a product made from an alloy with an element content of 95.8% will not last long, so it is not practical to use such metal in the mass production of jewelry.

What other types of gold are there in jewelry? The number 925 is not in the specified list, because it refers to silver markings. For this metal in the Russian Federation there are 800, 830, 875, 925, 960 and 999 standards. According to the requirements of Russian legislation, the mark with the number 925 can only appear on a silver product.

Marking of silver samples.

Theoretically, the existence of 925 yellow metal is possible, that is, it can have the same markings as cheaper silver. But in world standards that apply to jewelry activities, there is no such gold alloy. Gold 925 will be practically no different from the already available options, as well as the pure substance. It will be inconvenient to use it in production due to the technical characteristics that are transferred to the alloy from other components of the alloy.

925 silver marking

The history of silver jewelry keeps in mind many legends and beliefs associated with this metal. At different times, magical and sometimes even medicinal properties were attributed to it. What exactly is an alloy, does 925 contain gold or silver? A ligature marked 925 does not contain gold at all; it contains 92.5% silver and 7.5% additional components, which usually include germanium, silicon and platinum.

 Due to the high concentration of the main precious metal, such an alloy is called sterling. The components of silver alloys differ from those of gold alloys. They provide the silver alloy with enhanced strength and the desired shade of the finished jewelry.

 Metal markings from 720 to 830 are characterized by a high copper content, which is expressed in their yellowish tint and poor resistance to oxidative processes. These samples are used mainly in industrial production.

875 silver is sometimes used in jewelry, but due to its yellowish tint it cannot boast of excellent aesthetic qualities.

The 960 marking is rarely used for another reason: products of incredible beauty can be made from such a precious metal, but they will not be durable.

925 silver is valued by jewelers because of its ease of processing: very complex filigree jewelry can be made from this metal. This sample is most in demand compared to other precious metal markings. Lower-order samples oxidize faster and lose their attractive appearance.

SILVER ALLOY MARKED 925 IS EXTREMELY RESISTANT TO EXTERNAL INFLUENCES, AND THE BEAUTIFUL LINE OF THE PRODUCT IS CAPABLE OF PLEASURE ITS OWNER FOR A QUITE LONG PERIOD OF TIME. THIS SILVER IS CALLED ELITE.

Metal with such characteristics is sometimes rhodium-plated - it is coated with itself. This procedure increases the brightness of the jewelry and also provides it with additional protection from scratches.

The price of a gram of metal is determined based on the fixing of the London Stock Exchange. The cost of finished jewelry includes not only the cost of raw materials, but also other components:

• Cost of the jeweler's work;
• Taxes;
• Import costs if raw materials are purchased abroad;
• Seller's profit;
• Brand awareness.

Even taking into account all the components, the cost of high-grade silver is acceptable for many consumers. 925 gold would cost several times more.

925 precious metal is used to make elegant jewelry, which in its aesthetic characteristics is in no way inferior to gold products. 925 silver marking is very popular among buyers, this is confirmed by metal quotes, demand in stores and the number of requests on the Internet. Consumer interest is due to the quality of finished products and the high content of the substance in the master alloy.

Not only jewelry, but also cutlery are in demand. They are durable and characterized by a beautiful shine that does not lose from regular contact with food.

How to distinguish silver and white gold?

High sterling silver jewelry is characterized by an attractive appearance and beautiful shine. Often this silver looks like white gold. Unscrupulous sellers take advantage of this feature, offering customers cheaper metal under the guise of luxury jewelry. How to distinguish them from each other?

The first thing you should pay attention to is the brand. Gold cannot be 925 standard. The mark on silver has the shape of a barrel, and on gold it is a slightly elongated rectangle. Even if you cannot distinguish the shape of the mark, you must look at the number on it. If it costs 925, you have a silver product.

White gold ring.

Don't forget that the two elements have different densities. This characteristic can also be used to determine the metal. To carry out calculations, you need to weigh the products on high-precision scales and calculate the density value using the formula. The obtained result is compared with the table of density of precious metals. This method is only suitable for jewelry without stone inserts.

It is necessary to compare the products externally. In terms of visual perception, white gold has a brighter shine compared to silver. The problem is that it is impossible to draw final conclusions about the material of the product based on this method of verification. The procedures of plating other metals and rhodium plating on silver items make visual comparisons much more difficult.

Determining whether you have 925 silver or white gold is sometimes quite difficult. The first sign that you need to pay attention to is the presence of a mark, its shape, and the meaning of the marking. The number 925 in the stamp in the form of a barrel indicates that the store is offering you a silver product. Then you need to evaluate the appearance of the product, pay attention to its color and shine.

WHITE GOLD AND SILVER ARE VERY SIMILAR IN APPEARANCE, BUT THE BRIGHTNESS OF THE LINE AND THE COLOR TONE CAN INDICATE YOU TO THE ORIGINAL METAL OF THE JEWELRY.

Not the last characteristic is the price of the jewelry. White gold is an alloy of a special alloy, the final color of which is determined by additional components. Yellow precious metal, regardless of its shade, is more expensive than silver jewelry.

925 - a sign of the highest quality silver

925 silver is called pure metal and is considered to be the highest quality jewelry alloy. Various products are made from it: pendants, chains, hairpins, cutlery, candlesticks, earrings, bracelets.

Features of the precious metal

The metal presented is classified as precious. Like all precious metals, it has a special marking that indicates the composition of a particular alloy. In most cases, precious metals are not used in their pure form. This is due to the fact that they are too soft and easily deformed. During operation, such products quickly wear out and lose their original appearance.

Therefore, 925 silver earrings, chains, rings, cutlery and many other products are made from various alloys, to which copper, titanium, germanium, zinc are added, and silicon or bromine can also be added. This gives the products special strength and beautiful appearance. A 925 sterling silver ring, a 925 sterling silver chain, and earrings for which the same sterling silver is also used look especially beautiful.

The marking of the precious metal remains the same for other jewelry.

What does 925 silver mean? Too large a percentage of copper in such an alloy leads to a loss of shine in the final product - the jewelry quickly oxidizes and darkens.

The 925 version of the material is considered standard; this alloy contains more than 90% precious metal and copper, which is why such products have the shine and beauty of pure metal and are quite durable. An additional advantage is that such jewelry is easier to clean.

The basis for rings, chains, accessories for jewelry, pendants are often called sterling. This name comes from the ancient name of an English coin, and this alloy is usually used to make elite table metal and jewelry.

Recently, handmade jewelry has become very popular.

Healing properties of silver

Craftsmen often use accessories for jewelry marked 925. These can be earrings, silver wire, bases for rings, etc. Earring accessories - earrings, silver 925 markings for making jewelry are advisable to use due to the beneficial properties that this precious metal has . Products made from 925 silver markings have antibacterial properties.

Such decorations have a beneficial effect on the human heart. The metal is used in the treatment of nervousness and irritability. It has a calming effect.

If large silver jewelry is worn on the neck or finger, people with high blood pressure will feel relief. If you put the ring on the index finger of either hand, you can avoid intestinal problems and smooth out small wrinkles on the face. If the ring is placed on the little finger of the left hand, it will improve the functioning of the heart.

Rings, chains, and earrings made of 925 silver help increase hemoglobin levels, improve the functioning of the immune system, wearing such jewelry helps get rid of headaches and relieve nervous tension.

Making silver products

Earrings (925 silver markings) represent the basis for creating earrings. Such fittings allow you to avoid irritation while wearing (of course, if you are not allergic to this metal, this is quite rare); in addition, it is noted that such earrings do not oxidize, do not darken and retain a beautiful shine for a long time.

Silver wire 925 marking is used by craftsmen to make various jewelry: rings, pendants, earrings, etc. Most often, the wire is used for filigree (the ancient art of making delicate openwork patterns). Silver wire is used to create a variety of patterns: satin stitch, weaving, herringbone, lace, etc.

Soldering allows you to connect individual elements of filigree and create a unique piece of jewelry, while even the most massive chains or 925 silver earrings will not look vulgar or too heavy, but will emphasize your individual style and add sophistication.

Besides filigree, wire is widely used for the base of necklaces or earrings. Other accessories are also used, 925 silver versions (these can be pins, bases for rings, medallions, locks, bracelets, pendants).

925 sterling silver chain, earrings, silver are very popular today, as such products are affordable, practical and do not require special care.

The alloy of this metal has good ductility and ductility, and the products are thin and practically weightless.

Jewelry craftsmen appreciate the presented material due to its hard and durable properties; earrings or a ring of 925 standard reveal the play of light of stones, both precious and semi-precious, much better than similar jewelry in a gold frame. Silver ring, chain, earrings - silver is available in a wide range. Such products are sold in almost all jewelry stores.

Earrings made of 925 sterling silver are often bought for little girls, since such jewelry rarely causes an allergic reaction, and the antibacterial properties of the precious metal contribute to faster healing of punctures.

Quite often the buyer has a question: is 925 gold or silver? Unscrupulous sellers often pass off silver jewelry as white gold, but in this case, the low price of such jewelry should raise suspicion. Gold has the following markings: 375, 583, 585, 750 and 958.

Such alloys are used to make various products; pure gold is marked 999. But the metal is too soft and easily deformed, so in its pure form it is not suitable for creating jewelry and other products.

Silver items can be coated with gold plating, which misleads the buyer. This type of sample is only available for silver items.

Not only jewelry, cutlery, candlesticks, but also stationery are made from this material. A silver pen, for example, is considered an expensive gift for people whose prestige it is desirable to emphasize.

925 standard is gold or silver, methods of determination

The 925 sample causes a lot of controversy among collectors and experts in this field. The question is very simple, 925 sample - what is it, gold or silver?

Of course, experts in precious metals quickly determine what kind of metal we are talking about in a particular case, but what about ordinary people? For users it is a white-silver metal. Let's take a closer look at this issue and find out how to determine the type of metal when the product has a 925 standard.

Read: Real ways to tell the difference between silver and white gold

925 metal – gold or silver?

According to the current standards in the Russian Federation, the 925 standard is used only for silver products. In fact, it is the highest standard of silver and is often confused with white gold. In many countries around the world, gold cannot be 925 fine.

If 925 silver is coated with rhodium so that it shines and does not oxidize, then even a specialist will have difficulty identifying the base metal.

Interesting: Rhodium plating of silver - advantages and disadvantages

The alloy contains 92.5% pure silver and 7.5% impurities to strengthen the material. Comparing 925 gold with this alloy, we can say that if such a material existed, it would not be too different from 999 gold, since the percentage of the purest metal in the total mass is very large. Producing products from such material will be extremely inconvenient and not profitable. Hence the conclusion that 925 gold does not exist, and if it does exist, it is in very limited quantities.

How to distinguish 925 silver from “white gold”?

Having found out that a metal with a hallmark of 925 is definitely silver, it is also worth knowing about the method for determining it. Sometimes scammers take advantage of the fact that people cannot determine the quality of the metal themselves. They sell silver of the lowest standard with the hallmark 925. In order not to make a mistake with your purchase, you should focus on the following points:

It is worth focusing on the price. For quality products, sellers ask a fairly high price. If we are talking about “white gold”, then the price will be even higher.

It is almost impossible to visually determine the quality and composition of the product, since scammers use all kinds of coatings. The only option is testing with reagents.

Sometimes, traders coat silver with a thin layer of gold and pass the product off as gold. Substitution can only be detected in laboratory conditions.

Ideal alloy

The purity of silver, as well as the cost of products made from it, is determined by the ratio of the precious metal to the impurities contained in the alloy. The highest standard is 999, but such silver is practically not used to create jewelry. It is too soft and plastic and, therefore, products made from it will quickly lose their sophisticated appearance.

Attempts to find the ideal ratio of precious metal and impurities of various origins led to the emergence of 925 silver. This figure says that a kilogram of alloy for the production of jewelry contains 925 grams of precious metal. The remaining 75 grams are copper, which increases the performance characteristics and preserves the decorative value of the alloy.

A pound sterling or more than half a kilo of silver

In an era before international standards were established, many technologies existed to make silver rings, brooches and coins more durable. For this purpose, zinc, platinum and other elements were added to the alloy, which were supposed to preserve the beauty and shine of the noble metal.

In 1215, King Henry II of England turned to the German family of goldsmiths with the surname Easterling with a request to make silver coins for his country. The high quality of the work was appreciated by the monarch, and the money itself was called sterling. A pound sterling is 0.45359237 kg of 925 silver, which is currently the highest quality standard.

What kind of jewelry silver is there?

There are many types of silver processing, which allows you to give each product a unique and magnificent look. Accordingly, a gram of 925 silver is not the only indicator that determines the final cost of jewelry.

One of the most expensive technologies in jewelry is coating silver surfaces with a thin layer of rhodium. This metal allows you to protect any silver items from corrosion and give them a bright white color.

Lovers of “aged” silver especially appreciate the patina that forms over time as the metal oxidizes. Jewelers have long appreciated the aesthetic advantages of such jewelry and are actively using the technology of artificial blackening of silver.

The filigree work of a jeweler involves working with small elements and thin wires made of precious metals. Typically, gold and 925 silver are used to make original light, almost airy jewelry, the price of which determines the initial cost of production. However, later the cost of such rings and pendants may increase significantly, since you will have to pay extra for the individual painstaking work of the master.

Composition of different silver alloys and their scope of application

Silver is a more versatile metal than gold, as it is used not only for making jewelry, but also in the jewelry industry. In contrast to the prevalence of gold of the highest standard, the highest and most popular standard of silver is 925. This means that the characteristics of the metal can be presented as follows: “silver: the alloy composition contains 92.5% precious metal, impurities - 7.5%.” Therefore, buyers are interested in the composition of the alloy and the metal impurities that are included in the alloy.

Silver products

Composition of alloys with silver

To form an alloy with silver, several impurities are not added. Only one metal is used as an addition to give strength and durability to the jewelry or other product. Thousands of silver is too soft, it does not hold its shape, and therefore it requires an alloying process. The following is used as a ligature:

• Copper. The most commonly used metal. This is what gives it the yellowness. The greater the amount of copper, the yellower the product.
• Platinum. An expensive element that imparts durability and reduces oxidation.
• Nickel. Harmful to the body because it tends to accumulate and cause allergies.
• Gold. An alloy of silver and gold is called white gold. In addition to silver, other metals are added to white gold. But this option is the most popular, reduces the cost of decoration and looks stylish.
• Cadmium. An expensive element, it is used in jewelry only by order of the buyer.
• Zinc. It wears off quickly and also leaves black marks on the skin.

Each impurity has its own advantages and disadvantages. For example, platinum and cadmium are very expensive metals. Therefore, they are not used in decorations too often. Such jewelry will cost more than its gold counterparts.

Each metal added to silver imparts a new shade to the piece. And in this way you can solve the problem of silver oxidation and blackening. It is enough to apply a layer of rhodium to the product. It will add shine to the jewelry, and you won’t have to clean it after a while. Products made from rhodium-plated silver resemble white gold in appearance.

Most often, copper can be seen as an auxiliary element that gives strength to the alloy with silver. But adding this metal in large quantities affects the color, giving the product a yellowish appearance. Copper also promotes oxidation.

Silver plate

Silver samples and their use

There are samples of silver, and depending on them you can understand whether this jewelry is high-quality or low-grade. The first most popular silver standard is 925. It is used in jewelry. Metal of this standard produces beautiful and noble jewelry with a silvery tint.

In England, silver has long been used for minting coins. This is what distinguished the country from the rest, where it was customary to use gold. Since then, 925 silver—and this is what coins were made from—has been called sterling. Therefore, now this term not only applies to the UK currency, but also means 925 standard.

Even table silver is most often made from this sample. This composition is characterized by bactericidal properties. Uncoated 925 sterling silver can kill germs. That’s why even baby spoons are made from it. Good silver for these purposes would be the use of 916 alloy. Devices made from it are somewhat cheaper.

Carat levels from 720 to 830 are considered low for jewelry. They are used only in industry. Alloys are not too expensive. Therefore, even household items can be made from them. They quickly oxidize and turn black in air; such materials require a protective coating.

silver ring

The thousandth sample of silver, which does not contain any impurities, is popular only among residents of East Asia. They claim that silver in its pure form is endowed with mystical properties, will protect against evil spirits and relieve diseases. Of course, jewelry is not particularly durable and wears out quickly.

Recently, blackened silver has become popular. The decoration is specially given an old look, which makes them look like antiques. Now this is done using oxidation, and the composition of silver in this case corresponds to its standard. The technique is often used in the manufacture of accessories and decorative items. And for jewelry you can apply the matting technique with a special chemical suspension. But such silver will also turn black over time.

The following are used as counterfeit precious metals:

• Cupronickel. It contains no silver, only copper with nickel and sometimes iron. Since nickel has been recognized as a harmful component, it is better not to buy such products, especially in the form of cutlery.
• Nickel silver. Cupronickel alloy with zinc. This is what is most often passed off as real silver or items enriched with silver. But in reality, such jewelry is nothing more than ordinary jewelry that has no value.

Since cases of counterfeits have become more frequent, remember that if the jewelry does contain silver, it will be stamped or the seller will provide a certificate of quality. Do not buy products online or at unofficial points of sale. The composition of a silver item determines its cost, quality and durability.
