What does 24 carat gold mean?

24 carat gold - how much is it, what is it, what is the price for 1 gram today

Good afternoon, dear readers. The issue of jewelry quality is always relevant. In the article I will talk about the highest standard of gold, how to use it, give recommendations for care and answer the question: how much is 24 carat gold?

What is carat

The name of the metal comes from the Latin word aurum - “light of the rising sun.” The term “carat” is used to indicate the weight of jewelry. The generally accepted abbreviation is ct. The weight of one carat is 200 mg. In England, this unit is used to determine the purity of gold. The higher the carat number, the fewer impurities in the metal. Depending on the alloy, metal is divided into 7 classes.

Origin of the word

The word "carat" comes from the Arabic qīrāt, the Latin carat, which means "carob pods". The plant was valued by jewelers in eastern countries. The fruits were distinguished by a constant shape, and the ancient masters called them “curatonia”.

The Egyptians, Romans, and Greeks were looking for a standard for comparing precious stones. This is how the comparison went with the seed, which weighed almost 200 mg.

How to determine carat content

There are two systems used to indicate the purity of gold:

Carat determines the percentage of pure Au. The system is common in Great Britain, America, Switzerland and a number of other European countries. Among the British, 9-carat gold is popular, in the United States - 10, 14-18, India - 22, and the Chinese prefer 24 carats.

The purest alloy is 24 carats. To calculate the proportion of additives, you need to subtract the carat from 24. 9K contains 9 parts of gold and 15 additives.

How to convert to the metric system and sample correspondence table

In Russia and the CIS countries, the metric type of notation is common. It refers to the amount of Au without impurities per 1000 particles. A 750 sample product contains 750 parts of pure metal and 250 particles of impurities. That is, each kilogram of this sample will contain 750 g of gold and 250 g of alloys.

You can convert the carat system to the metric system using the formula:

24*Y:1000, where Y is the fineness of gold in the metric system.

For example, 24*375:1000 = 9. 375 gold in the metric system is equal to 9K.

Convert the metric measurement system to carat using the formula:

1000*X:24, where X is the carat measurement system.

1000*9:24=375.

How to correlate the metric and carat systems is indicated in the table.

Metric system	999	958	750	585	583	500	375
Carat system	24	23	18	14	14	12	9

Legislative regulation

Russia provides for strict regulation and quality control of metal. In Decree of the Russian Federation No. 372 of April 5, 1999, the Ministry of Finance is assigned the responsibility to control the certification of precious metals and products made from them. Certification is required:

1. Cut gemstones. They are tested at retail.
2. Diamonds without jewelry processing.
3. Unique nuggets.
4. Minerals and recyclable materials with admixtures of precious metals.

Resolution of the Russian Federation No. 394 of May 6, 2016 “On testing, analysis and hallmarking of jewelry and other products made of precious metals” establishes:

• types of products subject to the branding procedure;
• procedure for providing the brand;
• labeling methods;
• reasons for refusal;
• sample setting algorithm;
• restrictions on the use of solders.

A mark with a mark indicates the purity, that is, the purity of the precious metal. They are divided:

• 375 – the percentage of pure gold is 38.5%;
• 500 – half consists of impurities;
• 583 – 58.3% gold;
• 585 – 58.5% Au;
• 750 – 25% base metal;
• 958 – 0.42% impurities;
• 999 – the purest gold, 24 carats.

The most common markings are 585 and 750. They are distinguished by increased strength and hardness.

What kind of sample is this?

24 carat gold is 999 fine. Why not 100%? There is no pure metal in nature. Refining, that is, the procedure for removing impurities, leaves only 0.01 percent of additives in the gold ore. 24 carats are considered elite.

A little about this test

The state gold reserve is formed from 24 carat metal. In Rus' it was called red for its red color when heated. To obtain the purest metal, the ore is subjected to an expensive refining process.

Composition and properties

The metal consists of 99.9% pure gold. According to State Standard No. 30649-99, additives can be lead, iron, antimony, bismuth, copper, and silver.

The amount of additives should not exceed 1/10 percent. By agreement with the Assay Office, palladium and platinum can be used as additives.

Au 24 carat has a number of features:

1. Temperature changes and high humidity are not dangerous for the precious metal. Au 24 carat is ductile and corrosion resistant. The surface is not covered with plaque under any conditions.
2. A metal of the highest standard, like any chemical element, is exposed to the aggressive effects of chlorine, a mixture of nitric and hydrochloric acids of high concentration.
3. The product turns out fragile and soft. Jewelry is easily deformed, so jewelers rarely use 24-karat gold.
4. It is used extremely rarely as a material for the jewelry industry due to its high cost.

Strength

24 carat gold has a strength of 120 MPa. It is classified as a material subject to deformation. Expensive jewelry breaks under physical stress.

The hardness is 18 HB. The metal is soft, marks remain on the surface if you run a knife across it. Melting point – 1063 degrees Celsius. The color of the molten metal is greenish. Aurum boils at 2947 °C.

Pure 24-karat gold is malleable and ductile. One gram can be rolled into foil with an area of ​​1 square. m or make 2.5 m of wire.

Alloy shade chart

The color of jewelry alloys depends on the type of impurities. 24 carats is a pure metal, there are practically no additives in it. Therefore, the color remains constant - bright yellow. The table shows the color change of Au with various impurities.

Share of gold, %	Proportion of impurities, %	Main composition of impurities	Alloy color
99,9	0,1	Silver, palladium, platinum, copper	Yellow
96,0	4	Copper	Yellow

Silver, copper	Yellow
Silver, copper	Green
Nickel, silver, zinc, copper	White
37,5	62,5	Copper, silver	Red
Silver, palladium, copper	Pink

Brand

Precious products are subject to mandatory branding. This procedure is entrusted to the Assay Supervision Inspectorate established by the state. The shape of the stamp is a blade, consisting of 3 blocks:

• inspection code;
• assay mark;
• sample designation.

The Russian print depicts the profile of a woman's head in a kokoshnik, turned to the right. The form of the brand was introduced in 1994.

Each 24k gold piece contains a seal secured with white thread. Unsealed products are not allowed for sale.

How much does 1 gram of gold of this standard cost?

The highest standard is more expensive than other alloys. The cost is determined by the amount of gold reserves and the dollar exchange rate. According to the Central Bank of the Russian Federation, the average price of a gram of 24 carats today is shown in the graph:

Price for 999 standard according to the Central BankMarket value of the standard todayPrice for scrapPrice in jewelry

Difference between 14 and 24 carats

The most important difference between the metals of these samples is the content of impurities. For 24 carats, according to GOST No. 30649-99, the ligature does not exceed 0.1%, for 14K – 41–41.5%. This means that the highest sample consists of almost 100 percent Au, and 585 - only 58.5%.

Cleanliness, hardness and durability

24 carat gold is highly chemically resistant to aggressive environments, but its mechanical properties leave much to be desired. Products made from it are soft, easily deformed, the surface is scratched and dull.

A product made of 585-grade metal does not lose its shine over time, and gains hardness and strength thanks to the addition of copper.

Color and price

Color 24K – bright yellow. The authenticity of coins and chervonets was checked using heating. If the color was red, then the metal was clean. As the gold cools, it acquires its primary color. Due to the small amount of impurities, the color does not change.

14K metal has a wider color palette. A high content of copper gives a red tint, silver and copper - yellow, silver - green.

The price of samples differs significantly: the average price of a gram of 24 carats is 2500 rubles, 14K is 1600 rubles.

What to consider when purchasing products

Commemorative badges, medals, precious coins, and bank gold bars are made from gold of the highest standard.

Au 24 carat is a heavy metal. The weight of the products is at least 10 grams. Accordingly, the cost of a small product will be high. Pure gold jewelry is rare. Mostly, jewelers make massive wedding rings: thanks to their volume, they will retain their shape.

The surface of the product is easy to scratch, so the jewelry should be stored carefully.

How to distinguish gold from gilding

Counterfeiting of jewelry and high-quality items is common. The Assay Office claims that 15% of all products are counterfeited annually. Basically, products made of silver, copper, brass, coated with a thin layer of 24 carat gold are passed off as noble metal. To avoid falling into the trap of scammers, use these tips:

1. Before visiting a store or pawnshop, stock up on a magnifying glass. It will help you better see the mark on the product. This aurum must be marked with the Assay Supervision Inspectorate indicating the sample. Gilded items do not have a hallmark or receive a base metal marker.
2. Pay attention to the edges of the jewelry: gilding is a thin gold coating on an item made of any metal. It tends to wear off over time. If the color is uneven, then the item is not completely gold.
3. Stock up on a magnet. 24 carat metal is diamagnetic and will not attract. But the impurities may include alloys that are attracted by a magnet.
4. Each ingot must have a certificate and passport.

You can have your metal checked without leaving the store. The main thing is not to damage precious products!

Care Tips

24 carat gold is an expensive pleasure. If you decide to purchase jewelry or collectible coins or bars, handle them with care:

• Always remove jewelry when doing household chores;
• trust cleaning to professionals;
• Store coins in individual packaging or numismatic albums.

Conclusion

So, 24 carats is 999 gold. The highest, but not applicable for most types of jewelry.

What is the difference between 14 karat and 24 karat gold? What determines the value of 14k gold?

14 karat gold is often used in jewelry, but what about 24 karat? Let's look at the differences between them.

The difference is in purity

The biggest difference between 24 and 14 karat gold is purity.

The purity of gold is measured in karats. 1 carat is equal to 4.17% pure gold in the alloy.

Judging by the numbers - 24 and 14, the latter alloy is less pure. 14k gold is an alloy consisting of pure gold mixed with other metals.

The reason why such alloys are used is that pure gold is very soft and jewelry made from it bends and wears easily.

Typically, additional metals used in gold alloys are copper, zinc, nickel and silver.

24 carat is pure gold (999 fine). The maximum possible purity in carats is 24.

Therefore, 24 karat gold is 100% pure, while lower purity alloys have metallic impurities added deliberately.

14 carat is a gold alloy, that is, a mixture containing additional metals in addition to gold. These additional components are used to improve the characteristics of the alloy.

The most common additional components are copper, zinc, nickel, silver and palladium.

Some jewelers avoid nickel because it can cause allergic reactions in some people, especially if the metal is used in low-karat jewelry.

If you calculate the actual purity of 14 karat gold, it turns out that it contains 58.3% precious metal (14/24x) (585). The remaining 40% is copper, zinc, nickel, manganese, palladium, etc.

Differences in Hardness

The different purities of 24 and 14 karat alloys result in different levels of hardness, which is why the alloys are used for different types of jewelry.

14K gold is used to make durable jewelry.

14K gold is relatively hard, making it a popular alloy. This characteristic makes 14k gold products more durable.

Jewelry made from this type of gold scratches less and lasts longer because it wears out more slowly than an alloy containing a higher percentage of the precious metal.

24k gold is too soft for jewelry and is very rarely used because the metal is so soft.

As a result, it can be easily scratched and easily deformed.

For example, a ring made of pure gold will be too susceptible to damage and parts (such as the teeth of the setting) will wear off very quickly.

Color

When it comes to color, 24k gold is an absolute winner, its tone being the actual color of real gold.

Any alloy with a lower purity will not have a true gold color, although 22 and 18 karat alloys are fairly close.

14K gold's yellow color is not as rich as 24K gold - the tone of 14K gold is paler in comparison.

However, its shade may vary depending on the presence of other metals in the alloy and their relative concentration. This is why you see 14k gold jewelry that is quite rich in color for the alloy of this purity.

Price

24 carat gold is very expensive, as there is no purer metal than this. 14 carats are much cheaper, which is why they are so popular.

Knowing that 14 karat is quite reliable, you can see why many people prefer it as a “sweet spot”. The purity of this alloy is not as low as that of 10-karat gold, and at the same time, 14-karat is not as expensive as 18-karat.

How to evaluate 14 karat gold?

Let's take a look at what factors influence the value of 14k purity gold jewelry and how you can estimate its value.

The value of a gold alloy depends on the amount of pure gold it contains. This means that in order to determine how much a 14k piece is worth (when sold as scrap), you need to find out its weight and, taking into account the purity of the alloy, determine the amount of pure gold it contains.

Once you know this, you can use current market prices to value it.

Let's see how you can determine the amount of precious metal in a 14-karat piece:

Weigh the product

Place your product on the scale.

Be sure to remove any other items—for example, if you're weighing jewelry with gemstones, don't take their weight into account.

Many jewelers use troy ounces and pennyweights to indicate weight (1 ounce = 20 pennyweights), so if you weigh your jewelry in grams or ounces, you may find these conversions helpful:

1 gram = 0.03215 troy ounce

1 gram = 0.64301 pennyweight
1 ounce = 0.91146 troy ounce

1 ounce = 18.22917 pennyweight

Calculate the amount of pure gold a

Now that you know how much your gold jewelry weighs, you can calculate how much pure gold it contains.

14K contains 14 parts pure gold and 10 parts other metals. This means that 58.3% of this alloy is gold (14/24 x 100). So you simply need to multiply the weight of your items by this percentage to find the precious metal content.

For example, if you have 5 grams of 14K gold, then it should contain 2.915 grams of pure gold (5 x 58.3%).

What is the cost of 14k gold?

The value of your jewelry depends on how much buyers are willing to pay for it.

Here we discuss the value of gold jewelry that is sold only as scrap. However, retail prices for new jewelry depend on more than just the amount of pure gold it contains; Factors such as the design and brand of the jewelry also play a role.

One way to estimate the value of 14k gold is to look at its market prices. Another way is to find out what dealers are paying per ounce or gram.

Market price

The current market price can be found from various sources online and fluctuates from day to day.

You should not expect to get the same price if you sell your jewelry to a dealer. These buyers typically pay around 70%-80% of the market price you see on international exchanges.

Dealer price

Dealers buy jewelry and other items to sell as scrap to recycling plants or to melt them down before resale.

To get a realistic idea of ​​how much money you can get for your 14 karat jewelry, check out the prices quoted by a number of dealers.

As mentioned, you should expect dealers to pay approximately 20% less per gram of pure gold for jewelry than the market price.

Can you get more money for 14k gold??

The above guidelines will be important to you if you are thinking of selling your jewelry as scrap.

However, if your gold items have antique value, a unique design, or are valuable collectibles, you could try selling them at an online auction to get more money.

Another option is to offer the jewelry to a jewelry store, which can either pay you cash or take the cost of the piece into consideration when purchasing a new one.

How is 14k jewelry marked?

The easiest way to check the purity of gold jewelry is to look at markings, usually stamped in less visible places.

14 karat jewelry will most likely be marked with a "14 ct" or "14 ct" symbol. Sometimes on jewelry you can see numbers expressed in parts per thousand.

The number used to denote 14 karat is 583 (which corresponds to 58.3% gold content), so if you see this stamp on a piece of gold jewelry, you can assume it is pure 14 karat.

Cleanliness check

Do you have a piece of gold jewelry but are not sure if it is really 14 karat? Let's look at how you can find out the actual purity of your gold.

If the jewelry does not have any markings, or if you have reason to doubt the markings, you can test it. There are two options: testing at home or in a jewelry store.

Using the Test Suite

You can test for yourself whether a gold piece contains 14 karat gold by purchasing a testing kit.

This test involves applying nitric acid to a gold sample and observing how its color changes as a result. Depending on the gold content of the alloy, it will react differently with the acid.

Here's what you need to do:

1. Rub the gold on the stone included in the testing kit until the product leaves a mark. (Do not scratch jewelry in visible places.)

2. Pour some acid from a bottle marked “14 K” onto the mark. (Each bottle contains an acid prepared at the exact concentration required to react with the specific purity of the alloy, which is indicated on the bottle's label.)

3. Observe the reaction of the acid with gold. If the mark does not change color, then its purity is higher than 14 carats. If the color changes only slightly, then its clarity is 14 karat or slightly lower. If the mark dissolves, then its carat is much lower.

If the gold you are testing turns out not to be 14 karat, then you can use the next higher or lower karat bottle to more accurately determine the purity of the alloy.

Important: The instructions above illustrate the general procedure for testing the purity of gold. Each test kit should have its own detailed instructions, so make sure you read them carefully before you start using it.

Jeweler testing

If you don't have a testing kit, or don't want to test at home, you can go to a jewelry store and ask to have your gold tested for a fee.

Many jewelers perform this test, and the methods they typically use are quite similar to the one described above.

The jeweler will likely take a small sample of your gold piece and apply acid to it to determine the exact gold content of the alloy.

What is the difference between 14 karat and 24 karat gold?

14k gold is very commonly used in jewelry, but how does it compare to 24k gold? Let's take a look at the differences between 14K and 24K gold.

(Editor's note - There are three most well-known approaches to samples: spool, metric and carat. The correspondence between them can be studied in the table)

Correspondence between gold hallmark systems

The biggest difference between 24 karat and 14 karat gold is the so-called "purity"

The purity of gold is measured in karats, with 1 karat equal to approximately 4.17% pure gold content. As you can see from the numerical value, 24K and 14K gold - 14K gold is less pure than 24K gold.

24K gold is the purest

The maximum possible value in the karat system is 24. Therefore, it follows that 24 karat gold is 100% pure, while lower karat gold has some “impurities” (additives) that are usually added intentionally.

14K gold is actually a gold alloy

A specific combination of metals that contains additional metals other than gold. These additional elements are designed to improve certain characteristics of the alloy.

If you calculate the actual composition of a 14K gold alloy, you will see that it contains 58.3% precious metal (14/24). The remaining 40% consists of impurities of other metals in varying quantities, such as copper, zinc, nickel, manganese, palladium, etc.

Color Differences

When it comes to color, 24-karat gold has no competitors, as its tone, color, and saturation are the most real color of gold, the “true gold color.”

Any alloy with a lower purity will not have a color that matches the hue of pure gold, although 22K and 18K gold can compete a bit.

14K gold, although yellow in color, is less saturated, pale, and does not resemble a “true gold color.”

Price difference

24k gold is the most expensive - purer and more expensive does not exist in nature. 14K gold is much more affordable, which is another reason why jewelry made from this gold alloy is so popular.

Returning again to the issue of durability - 14k gold is quite durable, which is why many people prefer it as a “golden mean” - its purity is not as low as 10K gold, at the same time, 14k gold is not as expensive as 18K gold.

Properties, cost and application of 24 carat gold - Glitter Gem

Good afternoon, dear readers. The issue of jewelry quality is always relevant. In the article I will talk about the highest standard of gold, how to use it, give recommendations for care and answer the question: how much is 24 carat gold?

Where is 24 karat gold used?

All gold products have a hallmark, which shows the quality of the metal used to make them. 24 karat gold is a pure metal that has a bright yellow color and is soft and malleable. Chemically, it always contains some amount of other elements.

The minimum possible size of impurities is 0.01% of the available mass. In industry, science and jewelry, both pure metal and alloys based on it are used.

Return

Metric and carat measurement systems

The karate system is used in Europe and the USA. 24 carats is a sample of gold without impurities, and 1 carat corresponds to an alloy in which the pure substance occupies 1/24 of the mass. According to Wikipedia, this international unit of fineness is officially called the “British karat of gold.”

The name of the term comes from ancient times, when when weighing jewelry, the fruits of the legume tree Ceratonia were used, the weight of the seeds is almost the same (from 0.198 to 0.2 g). If the alloy has a sample size of 12K, then pure metal contains 12 parts (50%).

In a sample of 18K, where the pure substance makes up 18 of 24 shares (75%), impurities occupy 6 shares (25%).

In the current Russian metric system, the standard is determined by the amount of pure gold in a kilogram (1000 g) of the alloy. What does this mean? For example, if an alloy has a 585 standard, then its kilogram contains 585 g of pure metal and 415 g of impurities. In the karat system, this corresponds to a 14K standard. Russian hallmark 750 corresponds to carat hallmark 18K.

To convert from the metric to the carat system, you need to divide the sample size in carats by 24, and multiply the result by 1000. In the Russian metric system, 24-karat (pure) gold corresponds to 999 samples.

Gold and its alloys

Using this table you can determine the sample in recognized metric systems

The bright yellow color of 24-karat gold develops a reddish (red) tint when the metal is heated. In Russia, such a change in color has long been considered a sign of the purity of the metal, which was called red gold.

Products made from it are valuable and beautiful, but they are fragile, subject to deformation and rapid wear, the appearance of microcracks and chips, and detachment of soldered parts. Therefore, in the production of jewelry, alloys of lower purity are used.

24-karat gold is also used in its pure form:

1. In jewelry, it is used to make large wedding rings and other massive jewelry; it is used to make items (including coins) that serve display and ceremonial purposes.
2. Anti-corrosion coatings used in high-precision instrument making always contain 24 carats of gold.
3. Due to the fact that the substance has low resistance to electric current and its thermal conductivity coefficient is high, 999 grade metal is in demand in radio electronics and other high-tech fields, and is used in nanotechnology to create thin films.
4. In scientific research, the material is used as a target in the study of processes occurring in nuclear reactions.
5. The highest grade metal is used by countries as a gold reserve.

When fused with other substances, 24-karat gold can acquire new properties and a different color, depending on the composition of the impurities:

1. If alloying is done with copper and silver, a soft and ductile, compression-resistant yellow alloy is obtained.
2. 24-karat gold alloyed with palladium or nickel is white and highly reflective.
3. If 24 karat gold is alloyed with copper (3:1) and a small amount of silver, the alloy will have a pink color.

Return

What should you consider when purchasing products?

The price of products made from precious metal primarily depends on its carat value; the cost of an item is also influenced by its weight and design. Jewelry is mainly made by machine, so if engraving and hand finishing are used, the price of the product increases significantly.

Pure metal, after losing its currency status, can be used as an investment instrument with high liquidity. Its price has dynamics that allow you to preserve and often increase the invested capital. So, if in 2004 a troy ounce cost $450, then by 2012 its cost exceeded $1,000.

Investments can be made either directly in bullion and jewelry, or through investments in bank metal accounts.

Products made from non-precious alloys can be coated with a thin layer of gold. Its application is carried out using a galvanic method, so gold plating can only be made from 24 carat metal.

The thickness of such a layer is small and only an order of magnitude greater than the atomic dimensions. Therefore, when purchasing such products, you need to know that the proportion of the pure substance in the total mass is insignificant (tenths of a gram), and the price should be close to the price of the product without coating.

As a review of price dynamics for pure gold and products made from it shows, the cost of both has been steadily increasing over the years. Will this continue for as long as possible? Of course, there is no exact answer to the question, but gold is a rare metal and its reserves are limited. Feedback from people using 24K gold metal for investment suggests that this instrument still retains its importance today.

Properties, cost and application of 24 carat gold

In this article:

• Properties
• Areas of application and pricing

To assess the purity of alloys containing gold, the metric system and the carat system are used throughout the world. In the first, the main measure of the value of aurum is the sample - the number of units of pure gold in 1000 units of the alloy.

The carat system uses a measure called carats - units, the number of which corresponds to the number of parts of pure gold in the alloy. To convert samples into carats, the number of carats is divided by 24 and the result is multiplied by 1000.

According to calculations, 24-karat gold corresponds to that which has a purity of 999.9, that is, pure aurum.

999 gold

Properties

Gold without any impurities is characterized by the presence of 999 grams of noble metal per kilogram of alloy. Many people wonder why 1000 grams of alloy cannot be 100% gold. In nature, any metal is not found in its pure form, so it is believed that it can have at least 1 unit (percent) of impurities.

24 carat gold is the highest quality and most expensive aurum, which has special characteristics. In fact, it is that noble metal that exists in nature in its original form.

Despite its high density, aurum is a very ductile and soft metal. For example, one gram of gold of the highest standard is enough to roll out a wide plate several micrometers thick.

Also, from this amount of metal it is possible to make a long thread the thickness of a human hair.

Aurum without impurities is known as an ideal conductor of heat and electricity. Gold is not afraid of such negative processes as corrosion and oxidation, so the metal can maintain its ideal appearance for centuries.

Areas of application and pricing

Gold of a value of 24 carats is practically not used in the manufacture of jewelry, since due to the physical properties of pure aurum, such products are deformed, scratched and even broken. Previously, wedding rings were made from gold of the highest standard. Such decorations were quite thick and massive, as well as expensive.

Today, 999 grade aurum is used in the following areas:

1. Medicine: the properties of the metal allow it to be used in medicine, in particular in dentistry. Gold is an ideal raw material for the manufacture of some elements of dentures - the metal does not deteriorate under the influence of saliva and food eaten by humans. Aurum can also be found in effective medications used in the treatment of certain autoimmune diseases, for example, rheumatoid arthritis.
2. Innovative technologies: anti-corrosion coatings of high-precision instruments are made of pure gold. The high coefficient of thermal conductivity of the metal makes it possible to produce the thinnest films from it for high-precision radio-electronic devices. In science, aurum is involved in research related to the study of nuclear reactions.
3. Economy: pure gold represents the reserves of the central banks of most countries in the world. Also, bars of such metal are offered to citizens by banks as an object of long-term effective investment. Investment operations are carried out by opening impersonal accounts that reflect the amount of acquired aurum. Purchasing commemorative and commemorative gold coins is also considered one of the most common investment methods.

A new iPhone made from 24-karat yellow and rose gold is on display at a store in Dubai.

Determining the price of 24-carat gold is a complex process that depends on several factors:

1. Volumes and rates of aurum production: the cost of a gram of the resource will fall as supply increases, and a reduction in the volume of metal on the market will provoke its rise in price.
2. Activity of investors in precious metals: investors become most active during a crisis in the economy - in an effort to protect their capital from depreciation, investors direct it into precious metals. At the same time, high demand for the resource generates an increase in its cost.

The price of aurum is indicated per 1 troy ounce (31.1 grams) or per 1 gram. Gold with a value of 24 carats is the most expensive in every country in the world. If we analyze the cost of this resource in Russia, we can distinguish 3 types of prices for the precious metal:

1. The discount price established by the Central Bank of the Russian Federation is 2313 rubles per gram.
2. Market value - 2311 rubles.
3. The highest price for scrap that is accepted in pawn shops in Russia is 2,080 rubles.

You can also highlight the price of metal set by commercial banks. In any case, it will be higher than the market price, since when purchasing aurum bars, the bank client additionally spends money on VAT and bank commission. As for coins, their value depends not only on the mass, but also on the complexity of the artistic design of the copies.

The cost of precious metals - this indicator cannot be called stable, however, studying the reports and forecasts of expert analysts will allow you to have an idea of ​​the situation in the corresponding market segment.

What is 24 karat gold and where is it used?

Gold has always been valued, and in ancient times it was considered a divine metal. Today, gold is used not only as a symbol of wealth, but also in medicine and in various industries.

Nature does not produce gold in its pure form; the metal extracted from the depths of the earth must undergo a purification process. With the help of refining - the so-called process of purifying gold - maximum purity of the material is achieved.

As a result of this purification, pure gold is obtained, which is used only in the manufacture of gold bars and coins, and is also used in medical products, industry and science.

999 gold bars and coins

Gold of this purification is used extremely rarely for the manufacture of jewelry; impurities are added to these products. This makes the metal somewhat cheaper and makes jewelry more affordable.

In Russian stores selling jewelry, we most often see products that are evaluated by a sample system. There is always a stamp with numbers on the price tags and on the product itself; the most popular standard is 585. But if you visit jewelry stores in Europe or Asia, gold jewelry there is valued in carats.

What are the differences, and what does gold purity mean? And how much is 24 carat gold?

What is carat and fineness?

Nowadays, in order to determine the purity of a metal, two systems are used:

• metric system of samples;
• carat

The metric system is used in the CIS countries and Russia. The principle of the system: how much gold is in the alloy per thousand particles, this will be the sample. For example, a product made of 585 gold contains 585 particles of gold and 415 particles of alloy - impurities that make up the product. That is, one thousand grams of the alloy contains 585 grams of pure gold and 415 grams of impurities.

All other countries use the carat system; this gradation shows the ratio of gold and impurities in 24 parts of the alloy. That is, 24 karat gold is 100% pure gold. If we compare it with the Russian metric system, then this is 999 standard. Essentially, one carat is a fifth of a gram, or 200 mg of gold.

If you dive a little into history, the karate system was first used in Spain. But the very origin of the word “carat” comes from the name of the carob pod. Once upon a time, the seeds of this tree served as a measure of weight.

Where is 24 karat gold used?

24 carat gold, or .999 gold, is rarely used for jewelry. This is the purest gold, containing no impurities or no more than 0.01%. It is bright yellow in color and very flexible.

Since ancient times, in Russia such gold was called red gold, since when heated the metal turns reddish. Since 24-karat gold is very soft, it wears out quickly and cracks appear. Accordingly, the products are very fragile, and such material is used extremely rarely for jewelry. Perhaps only for the manufacture of products for ceremonies and demonstrations, and at the same time they are made large and massive.

Higher grade gold is more often used as an investment. It does not corrode, and the reserves of this metal are insignificant compared to other metals. Countries use 24-karat gold as a gold reserve. More often it is stored in bullion, and today there are more than 30 thousand tons of this precious metal in the depths of banks.

Gold bars are profitable investments

This metal is used in radio electronics and modern nanotechnology, all this due to such material properties as low electrical resistance and high thermal conductivity.

In high-precision instrument making, gold of the highest standard is used for anti-corrosion coating. This metal is often used in cosmetology and dentistry. In addition, gold compounds are present in some drugs for the treatment of serious diseases such as tuberculosis.

24-karat gold is also used in the form of sputtering on jewelry made from base metals. Jewelry is plated, and only gold of the highest standard is suitable for it.

Alloys with various metals are often used for jewelry. By the way, the color of the jewelry depends on what metal is added to the gold. For example, if the product is yellow, then copper and silver were added to the alloy, and there is much more silver. But if there is more copper in the alloy, then the product will be pink or even red.

For the effect of white gold, palladium is added, and for black, cobalt and chrome are used. You can also find shades of green - here cadmium and silver are added, and blue is obtained after adding high-quality steel. If you see a purple tint in gold jewelry, this means that aluminum has been added to the alloy.

What hallmark is 24 carat gold?

In the Russian Federation they use the metric system, and in Western countries they use the carat system. 24 carat gold is considered the purest, and if you are wondering what standard it corresponds to in the karat system, know that it is 999.

In addition, in different countries they use various designs and forms of marks on the product. The Russian stamp depicts a woman in a kokoshnik; the Ukrainian stamp depicts either the state emblem or a chestnut leaf, next to which the sample number is written.

The quality of the product is reflected by the amount of pure gold contained in the alloy from which the jewelry is made (since jewelry is not made from pure precious metal). Such a system is established and protected by government regulations and standards. For this purpose, the types of imprints and stamps have been standardized, the numbers on which indicate the sample number.

What are carats? Conversion to metric system

The carat is a unit of measurement for the purity of a gold alloy. It displays the same thing as a breakdown - the amount of cleanliness of the product. The only difference is that on foreign products the same thing is minted, only measurable in carats (from 9 to 24). The international system displays the measurement of the proportion of weight in 24 weight units of the alloy.

Table of correspondence between the metric and carat systems of precious metals.

In order to convert to the metric system, as well as calculate how many carats of gold will be in grams and vice versa, you can use the following formula:

24 : 1000 = X : Y, with X being the carat standard and Y being the metric standard.

Gold samples are calculated in carats as follows: X = 24 * Y: 1000

Thus, 585 is X = 24* 585: 1000 = 14K
Following the calculations, 585 is equal to 14 in the karat system.

In metric system it is calculated as follows: Y = 1000 * X: 24

That is, 18K is Y = 1000 * 18: 24 = 750
Thus, 18 karat gold corresponds to domestic 750 gold.

After some simple calculations, we get:

• 24K equals 999 fineness = 100 percent pure gold content
• 18K equals 750 = 75 percent
• 14K equals 585 = 58.5 percent
• 12K equals 500 = 50 percent
• 9K equals 375 = 37.5 percent
• 8K equals 333 = 33.3 percent

It must be added that 18K gold is considered high quality, 12 and 14K are medium, and 8,9 and 10K jewelry is the lowest quality.

Popular rings made of gold of various carats.

Thus, 1 carat of gold, when calculating how many grams it is, will be equal to 0.2 grams.

A little about samples

999 standard or 24 carats is considered the purest gold, the percentage of impurities in which is no more than 0.1%. To put it in the old fashioned way – “chervonnoe”. It is highly fragile and bends easily, which is why it cannot be used in jewelry.

But on the other hand, before the October Revolution of 1917 in Russia, wedding rings were made from it, which were also in demand among the “new Russians” in the 90s; they were very thick and massive, weighing about 8 grams or more.

The price for 999 samples is, logically, the highest.

375 is considered one of the lowest quality in the world. 9 carat gold, if you calculate what standard it will be equal to, is closest to 375.

Sample 375 is unpopular in Russia.

At the moment, you can only find one alloy that is even lower quality - 333 or 8K.

In the Russian Federation, 375 sample is a very rare guest. It is rarely used in the jewelry industry. For this reason, on the shelves of domestic stores it is found in the minimum list of products.

The low content of pure gold in such jewelry does not have the best effect on the brightness of the surface and does not attract potential buyers. Moreover, some people experience allergic reactions when wearing such products due to impurities in the alloy.

What hallmark is 10 karat gold? In fact, this question misleads many people. 10K is somewhere between 375 and 585, containing 416 grams per kg of pure aurum. Thus, 10 carat gold is of low quality, and it is impossible to say exactly what standard it corresponds to on the Russian market, because we do not have 416 in use.

Foreign gold and gilding - consider the difference

Foreign gold purchased in jewelry stores in Italy, Turkey, China and other countries does not always meet Russian standards, or in other words, it cannot be considered a quality product. Most often, such gold is imported illegally, bypassing both customs control and state control authorities.

According to statistics, seventy percent of gold imported from abroad is fake, so you need to be very vigilant when choosing foreign jewelry.

It must be remembered that foreign products, even if they are genuine, differ from Russian ones in shade and composition; the vast majority of jewelry is yellow or white, with a minimal copper content.

What types of gold are there: 999, 750, 585, 375 and others

Gold is a metal that is perfectly susceptible to all kinds of mechanical damage and corrosion. To preserve the original appearance of the precious metal, other impurities are constantly added to it, in the vast majority of cases metals that are more resistant to damage.

Ligatures are metals used to give gold greater strength. Most often, silver or copper is used as a ligature. Pure gold (without any impurities) is highly susceptible to deformation, very much like simple plasticine.

Existing gold samples in the world

Gold hallmarks are special marks imposed by regulatory government agencies around the world to guarantee the presence of gold in jewelry or other types of products.

In strict accordance with the current legislative framework, regulatory government agencies strictly monitor not only jewelry stores, but also all other institutions that are to some extent related to the sale of precious metal. Therefore, before asking a pawnshop for the price of one gram of gold, you should make sure whether the institution has all the necessary licenses and certificates.

Today, there are four existing sample systems, but the most popular are: metric, carat, spool and lot samples.

Spool sampling system

Until 1927 in Russia, and after that in the USSR, a spool system was used to designate the sample of precious metal. The key difference between such a standard and the karat system was the designation of pure precious metal through the number 96. All other gold products containing an admixture of other metals were designated by other, lower numbers.

Try	Spool system	British gold carats	pure gold (%)
333	32	8K	33.33
375	36	9K	37.50
417	40	10K	41.67
500	48	12K	50.00
585	56	14K	58.33
625	60	15K	62.50
750	72	18K	75.00
792	76	19K	79.17
800	76.8	19.2K	80.00
833	81	20K	83.33
875	84	21K	87.50
917	88	22K	91.67
958	92	23K	95.80
990 (and above)	96	24K	99(and higher)

Carat sample system

Based on the British carat system, one carat (K) is equal to twenty-fourths of the alloy. A similar sampling system is common in Switzerland, the United States of America, Canada and Western European countries.

In Ireland, two standard systems are used equally: carat and metric. The noble metal of twenty-four carats (24K) is considered the purest. It is completely free of any other impurities.

Next comes 14-karat gold, which contains fourteen parts of the precious metal and ten parts of other metals.

Lot system of gold samples

A similar system existed in Germany until 1888 (before the use of the metric system). This type of gold hallmark is based on marks circulating in the Middle Ages among the Celtic, Scandinavian and Germanic populations of Britain. One stamp contained sixteen lots.

To convert a lot sample into a multiple, the lot system values ​​must be divided by two and then multiplied by three. In case of conversion to the metric system, the value of the lot sample must be divided by sixteen, and then multiplied by 1000.

Gold samples according to the metric system

In Russia it is now customary to use the metric system of samples. This system is characterized by ease of use. In other words, the metric system shows how many grams of noble metal are in one kilogram of the total alloy. For example, if one kilogram of alloy contains 415 grams of ligature and 585 grams of pure precious metal, then according to the metric system, this jewelry will have a 585 standard.

Russian jewelers in the vast majority of cases use the following samples:

• 958;
• 900;
• 916;
• 585;
• 750;
• 500;
• 375.

Previously, the 583 standard of the precious metal was widely distributed, which, according to the metric system, corresponded to 14K. Then a proposal was adopted to slightly change the gold standard (due to the difference in the price of gold) from 583 to 585 samples, so that Russian gold jewelry would not be at all inferior in value (per gram) to Western samples.

Which sample should I buy?

Everyone in their life has visited a jewelry store at least once and bought gold jewelry. If it was not a purchase for yourself, then it was a gift to loved ones, relatives and friends. In order not to panic and get confused in jewelry stores, you need to imagine in advance: the cost of the desired product, its sample, shade and appearance.

Having clear ideas in this regard, the seller will not be able to be taken by surprise with the question “ten carat gold, what is the hallmark?”, if the store uses not the metric, but the carat standard system. You can always remember that ten carats equals 375 fineness.

You should never chase after more expensive gold jewelry, or dream of owning the noble metal with the highest purity (999).

It is not for nothing that for more than a decade, people have given their preference to 585 standard, which has proven itself in matters of strength and long-term use.

Products with 999 fineness, although they have the highest level of gold content, are characterized by a high degree of deformation and can become soft. Such products are short-lived and are not suitable for constant use.

Legislative regulation: conclusion

In the Russian Federation, the content of precious metal in jewelry or another type of alloy is controlled by state regulatory services, guided by the decree of the Russian Government of June 18, 1999 - “On the procedure for testing and marking products made of precious metals.”

If gold was mined on the territory of the Russian Federation or intended for import, then it must have a Russian hallmark and a state hallmark. Specialists from the Federal Assay Center monitor the compliance of the gold composition indicated in the sample, as well as its actual presence.

Responsible for quality control of precious metals in the Russian Federation is the Assay Office, which is an integral part of the Ministry of Finance. The brand has its own distinctive designations. The Russian stamp depicts a woman wearing a kokoshnik.

In addition to the state stamp, jewelry made from precious metals can be marked with a name tag. This is a factory mark that confirms the presence of the name of the manufacturer. The name plate also indicates information such as the year the alloy was created and the first letter of the state inspection code.

Gold 24, 18, 14 and 10 carats: what is it and what is the purity?

Many people are familiar with the jewelry measure for determining weight. However, in the CIS, few people know what a carat is. One unit of diamond weight is considered to be the weight of 1 grain of carob acacia. Converted to grams, such a grain is equal to a weight of 200 milligrams and this mass is considered to be 1 carat.

For convenience, the karat system for gold samples, and not just precious stones, is adopted in some Western countries.

The gold carat does not reflect weight, but shows the quantitative ratio of the precious metal and the alloy (additive material) in the product. But if our alloy is characterized by the use of copper as an admixture, then in the West they mainly work with silver. Hence the difference in the color of jewelry.

Jewelry carat

The carat and metric systems are accepted as the main ones in the world classification of gold. The metric system is in force in Russia, Italy, Germany, Austria, and the CIS countries. Carat - in the USA, Great Britain, Switzerland, and other countries. For marking, jewelers use small stamps that are applied to the inner surface of the product. It is used to determine the country that produced the jewelry and the quality of the jewelry alloy.

Only jewelry with the state mark can be purchased as jewelry. Any goods that do not have a stamp should raise doubts about their authenticity, so you should not waste money on such purchases.

Gold is considered to be 24 carats as the maximum unit of measurement. This indicator corresponds to the highest standard - 999. In fact, it is pure precious metal, without foreign impurities. To determine the purity of a metal, it is heated. Pure gold acquires a reddish tint when heated. In the old days such metal was called red metal.

The name red was an indicator of the highest quality, since in the presence of even a small amount of impurities, the red effect was lost when heated.

Compliance with carat, metric systems and gold quality:

The ratio of base metal to alloy determines the value of the jewelry. The most expensive is 24-karat, pure gold of the highest standard, without ligature. In some countries there are things made of precious metal with a value of 23 carats.

The presence of silver, platinum, and palladium in the alloy gives the alloy a white color. Experts call this compound white gold. These metals belong to the noble group, therefore the cost of such an alloy is higher. Copper and nickel are considered inexpensive metals. The presence of these components reduces the cost of the product.

To be fair, it should be noted that copper not only gives a beautiful pinkish tint, but also increases the wear resistance of the metal. This is the indicator that has always favorably distinguished first Soviet and now Russian jewelry.

Alloy proportions

Different countries have their own habits and traditions that are typical for the jewelry market. In eastern countries, jewelry made of 24 and 23 carat metal has gained the greatest popularity. It is either pure or almost pure gold.

The cost of jewelry corresponds to the quality of the alloy. Such products are passed down from generation to generation. They look similar to the inexpensive yellow jewelry that we are used to seeing in our markets. Only a true connoisseur will distinguish a quality product from a cheap fake. Fine gold is a soft metal that is susceptible to physical deterioration.

In Western countries, jewelry made from pure precious metal is difficult to find. As a rule, it is used in the manufacture of demonstration items that are made for commemorative purposes.

To increase durability, filler metals are added to gold:

1. 18 carat gold (our 750 standard) consists of 75% base metal and 25% alloy. This is also an expensive compound in the jewelry industry. In Switzerland, it is legally prohibited to sell jewelry with a carat content below 18. This is worth knowing for lovers of foreign jewelry, who often end up in Russia without going through customs. Products of the highest quality are yellow in color.

2. 14 carat gold is the most optimal when taking into account the price-quality ratio. This is the most common category of jewelry. The use of such a proportion in the alloy is especially typical for Russia, Germany, Ukraine, and Belarus.

   Soviet 583 standard can be found on products made in the USSR, modern foreign 14 carat is 585 Russian standard. The ratio in this jewelry alloy is 58.5% base metal and 41.5% auxiliary.

   If foreign jewelry is characterized by a bright yellow color, which is explained by the presence of silver, then for products made in the CIS countries, a pinkish tint will be distinctive. This tone is given by the presence of copper. And this is a traditional connection that has remained since the times of the USSR.

3. In the UK, 9 carat gold is the most popular. The proportion looks like this - 37.5% is precious, and 62.5% is filler metal. Therefore, such a compound is considered a low-quality alloy.

Foreign companies, taking into account the demand for jewelry, make a stamp taking into account both the carat of gold and the purity.

This is convenient for all categories of consumers, since there is no need to independently convert one unit of measurement to another. In some cases, the letter “K” is written next to the number. The designation of a hallmark with 585 hallmark may look like 14K.

Jewelry has always been a profitable investment. Not to mention their aesthetic qualities. This is a contribution that never depreciates, can be kept as a family heirloom and inherited by descendants. Therefore, it is important to choose the right product, which will not only become a decoration, but will also provide a successful investment. The ability to distinguish a fake from an original, a high-quality product from a low-quality one, guarantees confidence in the future.
