How is white gold plated?

Why is white gold and silver rhodium plated?

Centaurus journal

Just a couple of weeks ago we told you about such a coating for jewelry as gilding. Anyone who missed it, forgot, or just wants to refresh their memory, please read “Gold Plating.” But today we want to introduce you to a slightly different coating for gold and silver products - rhodium plating.

Today you will find out

• What is rhodium? Interesting facts and a moment of history.
• Why is jewelry rhodium plated?
• How long does rhodium plating last on gold and silver?
• What methods of applying rhodium are there?
• Why rhodium plated white gold?
• What happens if a silver ring is not plated with rhodium?
• Is it possible to rhodium plate silverware?
• How to care for coated jewelry.

Rhodium is the most expensive and one of the rarest metals used in the jewelry world.

The price of 1 gram of rhodium is $225, while its neighbor platinum costs only $70 per gram.

It was discovered in 1803 by William Hyde Wollaston; in the periodic table we can find (Rh) at number 45. The name comes from the Greek word ροδον, translated meaning “Rose”.

But where is the connection between gray metal and a beautiful flower? Here’s the thing: Professor William discovered a bright pink powder in a nugget of platinum, which after processing turned into a silver-white metal that looked like aluminum. This was rhodium.

The world's rhodium reserves amount to only a few tens of tons, but the demand for this noble metal is very high. Due to the difficulty of working with rhodium, as well as its price, it is used only as a coating for silver and gold items.  

Rhodium plating of jewelry is the application of a thin (0.1-0.25 micron) layer of rhodium to jewelry, which imparts a special shine and shade, and also improves protection from mechanical and chemical damage.

• Resistant to chemical damage, e.g. reaction with detergent, sweat.
• They do not fade or oxidize. Therefore, we recommend that silver items be immediately coated with rhodium.
• With careful care you can wear it for up to 3-5 years.
• Increases resistance to scratches and other mechanical damage.
• They have a special noble shine and shade.
• Resistant to high temperatures.
• There are NO visible minor scratches on them.

Reader question: How long does rhodium plating last on gold and silver? How much does it cost to rhodium plate a ring or chain?

Answer YM: Depending on the type of product (bracelet, chain, ring or earrings), the price for coating with a protective and decorative layer of rhodium is from 13 hryvnia per 1 year of the product.

How long the coating will remain in its original form depends on how you wear it. If this is a chain, and you have it on you 24/7, then you can expect that after two years you will need to restore the protective layer. But in the case when rhodium-plated jewelry is not worn every day and is properly cared for, the coating can last from 3 to 5 years.

Since your product has a very thin layer of rhodium (thinner than your hair), using abrasives or hard cloths can significantly damage it. 

Important! How to care for coated jewelry?

• Remove jewelry before going to bed, going to the sauna or swimming pool.
• Clean only with a soft cloth, you can rinse under warm running water.
• Apply only to a dry body, waiting until the cream or perfume is absorbed.
• You need to store it in a special bag, separate from other jewelry.

There are only two methods of applying rhodium to precious jewelry - galvanic method and application with a pencil.

A rhodium pencil is a method of applying a layer of precious metal using an inexpensive device. This coating is inferior in quality to galvanic rhodium plating. Rhodium pencil can be seen in small jewelry workshops.

Jewelry coated with a rhodium pen can become scratched again in a short period of time or lose its protective layer.

 

The electroplating method of applying a thin layer of rhodium requires very expensive equipment. This method ensures a high quality protective layer.

By the way, we already mentioned electroplating in the article on gilding. So in rhodium plating, first the jewelry can be cleaned with ultrasound, degreased and washed, and then immersed in a galvanic bath, where, under the influence of current (a little physics), the jewelry is evenly coated with the thinnest layer of rhodium.

Do you love white gold jewelry? Have you read about this season’s trend – white wedding rings?

And now the most important question - did you know that white gold has a specific yellow tint , and the higher the standard, the greater the ratio of pure Aurum to alloys and the yellower the metal? It is rhodium plating that gives white gold jewelry a special noble white hue and incredible shine. Moreover, the places where precious inserts are set are covered with a thin layer of rhodium to emphasize the shine and play of stones.

 

Rhodium plating is also used in red gold jewelry. Because rhodium is silver in color, a thin layer of it on red gold gives a distinct hue to certain elements. In such a product there is no need to use gold soldering of several colors, and rhodium plating will help to enhance the design.

Black gold is new in the jewelry world. A stylish solution for incredible black diamond jewelry. The dark color enhances the beauty of the gemstones. Black gold can be obtained through an alloy with cobalt and chromium, or special rhodium plating.

  Reader question: What happens if a silver ring is not plated with rhodium?

We answer: Silver has poor chemical resistance, it can oxidize, corrode, tarnish and darken. That is, a silver ring needs to be constantly cleaned so that it does not lose its original appearance. Rhodium plating will cover the jewelry with a thin protective layer and add incredible shine. After such a procedure, the unprofessional eye can confuse silver with white gold or platinum.

Well, to finish, just a few words about silverware. Many people are afraid that rhodium plating can be harmful. Alas, not everyone studied well at school and thought about love in chemistry lessons =) There is no need to confuse Radium or Rhodium. The first is a harmful radioactive element, but Rhodium is a noble, HARMFUL metal.

Rhodium plating of silverware is the right solution for preserving cutlery in its original form. The only thing is that you need to wash them carefully without abrasives (soda).

White gold turns yellow: what to do, what can and cannot be used to clean it

Jewelry made from ordinary gold has not surprised anyone for a long time, so products made from white precious metal are becoming increasingly popular.

This type of gold looks like silver or platinum, but has the ability to change color. Such changes can be noticed after 2-3 years: the gold begins to turn yellow, which gives the jewelry a careless appearance. However, not everyone knows why this happens and how to prevent it.

Alloy composition

The precious material is not mined in its pure form ; in the jewelry industry, noble gold is mixed with other chemical elements. To create white gold you use:

1. Silver . The most popular companion material gives gold a silvery tint. Silver is sometimes used in combination with a small percentage of copper.
2. Platinum . This is the most expensive metal, so products with its addition are more expensive. Platinum gives jewelry a snow-white hue with a noble tint.
3. Palladium . Very rarely used.

Jewelry is plated with rhodium, which gives shine, pallor and a silvery tint.

Over time, due to the admixture of silver, jewelry may turn black. Rhodium plating protects products from this effect.

There are 2 processing methods :

1. Immersion in solution . This is the cheapest and easiest method, but this layer of rhodium comes off the jewelry faster. In addition, the solution is unevenly distributed over the surface of the product, causing areas of yellow gold to show through.
2. Galvanization. This is a higher quality and more efficient processing method using electrolysis and electric current. The layer lasts for a long time.

Why does white gold turn yellow?

The rhodium layer can last for 4-5 years, but sometimes the coating wears off and yellowness appears. This happens in the following cases:

1. Long-term wearing around the neck . Human sweat can gradually erode the rhodium layer, so over time the ring or chain may turn yellow even with regular care. In addition, the rhodium layer disappears due to friction.
2. Aggressive cleaning of jewelry . Concentrated acids and other chemicals cause white gold to yellow.
3. Mechanical damage . It is contraindicated to polish and grind white gold, otherwise the protective layer will be erased.

What products should not be used to clean white gold?

Do not use vinegar, toothpaste or other acidic cleaners to clean gold They contain chemicals that destroy the protective layer of jewelry .

To prevent the product from turning yellow, it is recommended to use preparations with ammonia

They delicately remove yellowness and do not harm jewelry. However, products containing ammonia should not be left on the metal for a long time, otherwise the opposite effect will occur.

How to care for white gold?

To maintain the whiteness and shine of jewelry, it is recommended:

1. Store jewelry separately . White gold should not be allowed to come into contact with other metals, otherwise the color of the product may change. It is better to store jewelry in separate bags or cases.
2. Avoid contact with water . White gold jewelry should be removed before cleaning or bathing. Jewelry should not come into contact with chemicals and water.
3. Professional cleaning . This procedure is carried out competently by jewelers: the master will carefully remove yellowness and other damage.

For minor defects, you can clean the product yourself using the traditional method:

1. Add 10 ml of dishwashing detergent to 1 liter of water.
2. Mix the ingredients thoroughly to obtain a homogeneous mixture.
3. Place the white gold item in the solution for 10-15 minutes. If the yellowness remains, the time can be increased by another 5 minutes.
4. Rinse the jewelry in water.
5. Gently wipe the product with a soft cloth and dry.

If the solution does not help get rid of yellowness , you can add a little soda to it. Under no circumstances should you use hard brushes during the cleaning process: they have a detrimental effect on the protective layer.

White gold is a popular precious metal that is increasingly being used to make jewelry. Over time, the material may turn yellow, so it must be treated with care. Only in this case will the product retain its original appearance.

White gold, white gold rhodium plating and platinum

All white gold products are rhodium plated. Rhodium is a platinum group metal. The process of coating with rhodium is called rhodium plating. The technology of rhodium plating is similar to the technology of silver plating and galvanizing. The depth of rhodium plating is measured in microns - millionths of a meter.

The rhodium-plated surface has a brilliant white color, while the true color of white gold is dull gray, and in lower quality compositions it has a yellowish or pinkish tint. Since rhodium plating is a coating, over time it wears off partially or completely, especially from rings. And from under it a real shade of white gold appears.

Erasing the rhodium plating

Rhodium, although very resilient, will eventually wear out as well. Wear depends on the shape of the ring. The wider its surface and in what “difficult conditions” it is worn: gym, cleaning, etc., the faster the rhodium coating wears off. Therefore, it is impossible to say how long it will last and how often the ring should be given for rhodium treatment.

Scratches appear on white gold items just as easily as on yellow gold items. They are simply more noticeable on a white shiny surface, since scratches partially damage the rhodium layer, and accordingly the difference between the damaged and undamaged rhodium surface becomes clearly visible.

On yellow gold items, scratches are less noticeable over time because the surface color does not change. White gold items can be ordered without rhodium plating. In this case, if the surface is damaged, the color of the product does not change and the scratches are less noticeable for a long time.

Caring for white gold jewelry

White gold rings remain in good condition for many years, if from time to time you take them to a jeweler for “renewal” - rhodium-plating. The cost of rhodium plating, depending on the ring model, is approximately 30 – 50 euros.

Simultaneously with rhodium plating, you can also polish the ring, which will remove deep scratches from the surface. It is also useful to check the firmness of the diamonds.

It is useful to check the firmness of the diamond fit in any gold or platinum jewelry at least once every three to four years.

In general, caring for white gold items is much different from caring for yellow gold items.

It is also important to remember that regardless of the material from which the decoration is made, cleaning must be carried out regularly. Depending on use, even weekly cleaning may be necessary, but generally once or twice a month. You will find more detailed information on cleaning jewelry in the section “Caring for Your Jewelry”.

White gold alloys

There are many different white gold alloys on the jewelry market. Sandberg jewelry uses only high quality alloys using palladium and no nickel. In terms of properties and color, these alloys are the best available.

There is a possibility of purchasing white gold products, on which, after the rhodium plating has been erased, a yellowish tint appears on the surface. This suggests that the palladium content in the alloy is kept to a minimum. With products from Sandberg, the possibility of such an acquisition is excluded!

There are also white gold jewelry on the jewelry market, the yellowish tint of which indicates that nickel has been added to the alloy (within the limits allowed in the EU directive).

After removing the rhodium coating from such products, a person may have an allergic reaction to nickel. I would like to add that an allergic reaction often does not occur immediately, but only after the coating is partially or completely erased.

In many cases, an allergic reaction can occur due to improper and irregular cleaning.

See our Jewelry Care section.

Platinum

Platinum is a more expensive metal, but in some respects it is a better alternative to white gold, especially for frequent and long-term jewelry use. The natural color of platinum is very close to the color of the rhodium-plated surface and is light white. Products made from platinum are not rhodium-plated because they do not change their color during use.

Over time, scratches appear on platinum jewelry, but as with yellow gold, they are less noticeable because there is no change in color.

Pros and cons of rhodium plating gold jewelry - Shine Gem

Hello, friends and random visitors. Now I intend to fully capture your attention in order to discuss with you the rhodium plating of gold - what it is, why it is used, what advantages and disadvantages jewelry processed in this way has.

What is it and what is it used for

Rhodium plating of gold (not to be confused with radiating) is the application of a thin layer of sputtering from another precious metal to a product. The substance used for this manipulation is rhodium. This is a noble precious metal of the platinum group, inert and hard. Another advantage is its high reflectivity, thanks to which it shines brightly.

This substance was discovered relatively recently - in 1803. Its content in nature is extremely low. No more than 30 tons of rhodium are mined annually around the world. The metal has a high cost, but at the same time the demand for it is growing every year, as new ways of using it appear.

Types of rhodium plating

Rhodium plating is used to achieve several purposes: the formation of a hard wear-resistant layer, the elimination of blackness in silver jewelry that occurs during the oxidation of silver, giving the product shine, and decorating inserts made of precious stones.

Standard

With standard rhodium plating, jewelry acquires a silver color with a cool, bright shine. Due to its hardness, rhodium perfectly protects soft precious metals from minor damage and scratches, preventing wear. The product remains attractive for a long time and looks new.

Black

Black rhodium plating, while maintaining its protective benefits, can give the decoration the noble blackness of an expensive antique item. The coating can range from pale gray to jet black. Such items inlaid with black pearls or black stones look amazing.

The effect is achieved by changing the chemical composition used in the rhodium plating of gold, as a result of which a layer of black rhodium oxide is formed on the surface of the product.

Rhodium plating technology

The process is carried out by electrolysis. Thoroughly cleaned jewelry is placed in special solutions and an electric current is passed through them. With this treatment, rhodium molecules are embedded in the top layer of another metal, forming a uniform, durable coating no more than 25 micrometers thick, which is 4 times thinner than a human hair.

White gold

When rhodium plating items made of white gold and silver, a layer of rhodium is usually applied to the entire surface of the item. This is due to the color of the base alloy - when the rhodium is erased, the damage will not be too noticeable, since the item itself is similar in color to the shade of the coating.

Red and yellow gold

Despite the same process technology, objects made of non-ferrous gold alloys are not sprayed over the entire surface, since over time the non-ferrous metal will begin to bleed through the rhodium, creating a sloppy effect and disrupting the aesthetics of the item. In products made from such alloys, the beds of precious stones are coated with rhodium. Due to the high reflectivity of this substance, the stones shine especially brightly.

Properties of rhodium-plated gold

Regardless of the color and grade, gold plated with rhodium acquires a silver-steel color and a bright shine. Due to the hardness of the protective layer, you can wear such things for much longer. At the same time, inertness to some oxidizing agents increases.

People who are allergic to gold can easily wear such jewelry.

What color is rhodium?

Pure metal is silvery white. Rhodium in typical compounds has a predominantly deep red color. Rhodium triamine trichloride is bright yellow, while rhodium oxide has all shades of gray up to completely black.

Cost of the procedure

Much depends on the method the jeweler uses for manipulation. Rhodium plating is offered in almost all jewelry workshops, and the indicated prices and the formation of the cost itself vary greatly: in some shops the weight of the product is taken as a basis, in others - the coverage area.

On average, a ring or chain can be plated with rhodium for about 300 rubles. However, prices for updating or restoring such coverage are usually 3-4 times higher than the initial procedure.

Pros and cons of rhodium plating

The obvious advantage is strengthening the surface layer of the metal, increasing service life due to increased resistance to scratches and damage. Many people find such jewelry more beautiful and sophisticated than jewelry made from conventional metals.

Another negative side is that such coverage does not last forever. It wears off and may be damaged or scratched. If the procedure is performed poorly, the rhodium layer peels off from the surface of the product. And even a perfectly performed rhodium plating will require periodic repeat procedures, for which you will have to pay each time.

How long does the coating last?

Depending on the product and the intensity of its use, the service life of such a coating will vary:

• earrings and brooches – from 5 to 10 years;
• rings – 1-3 years;
• chains and pendants – up to a year.

How to care for rhodium-plated gold

Such jewelry does not require exceptional care. In order for the coating to last for a long time, it is enough to remove the jewelry before visiting the shower or swimming pool, or performing household work related to water.

Contact a specialist in a timely manner to renew the coating so that your jewelry looks elegant and fresh.

Why does white gold turn yellow and what to do about it?

Many owners of jewelry are concerned about the question of why white gold turns yellow. Since ordinary gold has long ceased to surprise anyone, in modern jewelry stores you can increasingly find rings, earrings and pendants made of white gold. But the properties of this metal are such that over time it acquires a yellow tint.

Causes of yellowing of white gold

White gold is an alloy of yellow gold with white metals such as silver, platinum or palladium. One of the best options is platinum, which makes the precious alloy more durable and gives it a beautiful, noble shade. Most jewelers prefer white gold, as jewelry made from this metal is purer and more elegant. In addition, white color allows you to highlight all the advantages of a diamond.

Jewelry made from alloys of different grades is coated with rhodium, which provides shine and gives a silvery tint. Because silver is present in many jewelry items, it sometimes reacts with oxygen and darkens over time. The rhodium plating process is designed to protect the metal from this effect. Rhodium plating gives white gold a pale hue. There are 2 ways to perform rhodium treatment:

1. Galvanization. The essence of the process is the effect of electric current and electrolysis. This contributes to a better coating of the jewelry and long-term preservation of its beautiful appearance.
2. Immersion of the product in a solution with rhodium. This method is cheaper and easier to implement, but the rhodium layer wears off much faster. In addition, it is not always possible to cover the decoration evenly.

In many cases, the top layer of the piece will wear away over time, revealing the underlying yellowish layer of gold. This can happen if:

1. Wear the jewelry for a long time without removing it. The acidic reaction of sweat affects the rhodium layer and gradually corrodes it. This leads to the fact that after some time the ring or chain begins to turn yellow.
2. Wearing the product for too long. Due to friction, the rhodium layer can wear off. By the way, such a layer usually lasts about 4-5 years, and no visual changes occur.
3. The decoration is constantly subject to mechanical damage. Products made of white gold need care, so you will have to forget about grinding and polishing, unless, of course, you want to erase the protective layer.
4. Clean jewelry with aggressive substances. To avoid yellowing of white gold, do not use soda, concentrated acids or other chemicals to clean it.

How to restore white gold that has turned yellow?

How to care for white gold products to prevent them from yellowing and maintain their original appearance? Firstly, jewelry must be stored separately and not allowed to come into close contact with other metals, otherwise the color of the white gold may change.

Secondly, the greatest danger comes from perchloric acid and other chemicals, so be sure to remove your jewelry when going into the shower or pool. The same goes for the process of washing dishes or cleaning. Try to avoid contact of jewelry with chemicals. Thirdly, you should not clean your jewelry yourself.

It would be best to take them to a jeweler who will carry out this procedure correctly without damaging the top layer.

If you notice that a chain, ring or brooch has begun to turn yellow, do not be upset. Take the piece to a jeweler who will re-plate it with rhodium and restore it to its attractive appearance. If you decide to clean this metal yourself, make sure that there is no damage to the jewelry. Do not begin cleaning if there are gems that are about to fall off, damaged parts, or broken clasps or hooks.

What products should not be used to clean white gold jewelry?

Many preparations contain ammonia, which can be used to clean white gold, but you cannot leave it on the metal for a long time - this can damage the thin coating.

Vinegar is a strong acid that negatively affects jewelry. The same goes for acidic cleaners. When attempting to clean white gold jewelry yourself, never use toothpaste.

It contains chemicals that may damage or destroy the rhodium plating.

To ensure that the product does not turn yellow and makes you happy for as long as possible, you need to take good care of it. Keep this in mind when purchasing white gold jewelry. The yellowing effect is an elementary cosmetic defect characteristic of this metal. You can easily get rid of it, returning your favorite ring to its original beauty.

• Gold acrylic paint can be tinted, that is, you can give it the necessary golden hue for any color.

The composition can be used both for decoration and for restoration work on metal and wood. With its help you can paint polyurethane and gypsum stucco. Manufacturers produce the coloring composition in several types:

• classic paint in a sealed metal can - enamel;
• aerosol paint in spray cans;
• dry, in the form of a powder composition that needs to be dissolved.

Each type of decorative acrylic paint has different characteristics, color and application features.

Acrylic based

There are a lot of manufacturers of golden paint, and any enamel is of good quality. An example is Metallic Accents acrylic decorative paint.

The substance contains mica particles, which give the coating a golden shine and a magnificent shimmering effect. The manufacturer offers a varied color palette from light gold to dark brown paint. Enamel is suitable for any interior style; it can be used to paint wallpaper, wood furniture, walls, and it is suitable for ceramic tile floors. For work use:

Acrylic paint is produced by the manufacturer in a small jar complete with a base and top coat. It can be used to paint surfaces made of metal, plastic, plaster, wood, and ceramics indoors and outdoors.

An antique patinated coating is obtained by applying all enamel components:

1. The first layer is to first apply the primer in cans (included in the kit) to the prepared, cleaned surface, following the manufacturer’s instructions.
2. The second main layer - the enamel is mixed and applied in a thin layer. In the right places, the paint is immediately wiped down to the base layer to create a patina effect. The more second layer remains, the more aged the antique finish looks.

The composition is two-component. Dries in twenty minutes, suitable for interior and exterior decoration in an old style. In general, to get a brown patina, use any acrylic metallic paint of bronze and gold color. The surface is cleaned, degreased, base gold is applied, then bronze and clear varnish. As a result, you can get a spectacularly aged brown patina with an excellent antique imitation.

Acrylic paint in a can is a classic way to paint a surface, giving it the effect of an antique patina, antique coating, or Venetian plaster.

The benefits of aerosols

The modern market of paints and varnishes offers a large selection of gold-effect aerosol decorative paints with various color variations. Such compositions have a number of advantages.

What is remarkable about blacksmith's paints?

Since painting allows you to obtain interesting surfaces with different effects, it is used to decorate exteriors - gates, window bars, entrance doors and panels, bas-reliefs, fences (including painting fences in a cemetery). With the help of blacksmith's gold paints, it is possible to obtain an unusual surface with shiny chrome, artistic painting, or artificially age the metal.

Hammer compounds are very popular, which give the metal texture the appearance of dents and relief left by a forging hammer.

The use of several blacksmith's paints allows you to achieve a stunning effect of brown patina, and there are more than fifty options for such imitation. Even an inexpensive metal surface can be given a luxurious look and architectural appeal. In addition, forge paints significantly extend the service life of the metal and additionally protect it from moisture and corrosion.

Using dry acrylic, aerosol and enamel paints, you can introduce very bold and interesting design ideas, obtain incredibly beautiful unique surfaces, and add originality and chic to the interior. The only rule to follow is that there should not be too much gold. Only neat, no-frills gold accents will look appropriate and beautiful.

White gold

If an alloy of silver and copper is mixed with the more common red gold, then to obtain white gold, palladium or nickel is most often added instead of copper - these components make the color of gold white, or rather grayish. If you increase the silver component in white gold, the color of the gold will acquire a matte tint. An alloy is also common: gold + copper + nickel + zinc.

Previously, in most cases, alloys with nickel were used in the production of white gold, however, as it turned out, this metal quite often gives allergic reactions, which is why white gold is now most often produced using palladium. Moreover, in the countries of the European Union, since 2000, the use of nickel in jewelry has been banned at the legislative level.

In order for white gold to have a pure white hue, it is coated with a thin layer of rhodium.

To measure the gold content in a product, the concept of carat or British carat is used. One carat is one twenty-fourth of the total volume of the alloy.

In Russia, to apply a hallmark to jewelry made of precious metals, a sample system is used, according to which the content of precious metal is stamped on the product in the form of a three-digit number, which determines the mass of pure gold relative to the mass of the entire metal.

So for gold, both white and yellow, the most common standard is 585 standard, which corresponds to 14 carats; slightly less often in jewelry production, 750 standard is used, corresponding to 18 carats. However, 750 white gold is most often used as a setting for more substantial diamonds. Gold samples are the same for both white and yellow gold, as well as for other exotic shades.

White gold uses components that are more expensive than the more common yellow gold (palladium or platinum versus copper). In addition, white gold is often treated with rhodium, and this also increases the cost of creating jewelry. The price per gram of a white gold piece is higher than the cost of the same piece of red gold jewelry by about 20%.

White gold began to be used in products about a hundred years ago, at the very beginning of the twentieth century. The reason was the desire to create a replacement for silver, which darkens over time, and to obtain a material for setting unpainted diamonds, which would enhance their beauty and sparkle.

The fact is that it is the white base that best reflects the radiance and shimmer of the stones. The result of such research is obvious - white gold has become popular not only in jewelry with diamonds, but also as an independent metal in jewelry production.

It also goes well with black pearls and dark sapphires.

The popularization of white gold jewelry began after Lady Diana chose a white gold sapphire ring set with diamonds for her engagement ring. It was since then that white gold began to come into fashion and become more and more popular every year. And it is not surprising that today white gold jewelry is present on the shelves of all jewelry stores.

Jewelry store catalogs have a large selection of rings made of white gold - these include rings with diamond inserts, and signets with gold in two colors - white and yellow, and engagement rings made of white gold.

White gold rings make an excellent setting not only for precious stones such as diamonds and sapphires, but also for less expensive stones. Over the past few years, white gold wedding rings have become extremely popular. These wedding rings are not only unusual, but also fashionable and very interesting.

The number of earring models made of white gold is enormous, and any woman will find earrings based on her desires and her style.

These can be either white gold earrings plated with rhodium, or made of white and red gold or earrings with stones. White gold earrings pair best with clear or black diamonds, as well as dark blue sapphires.

Earrings made of white gold with black pearls look rich; such jewelry will add zest to your style and emphasize elegance.

How to clean white gold at home? — The second life of your jewelry

Knowing how to clean white gold will help you quickly restore the shine to your favorite jewelry without spoiling its thin, fragile outer coating.

:

Determining the scale of the problem

Before you begin the cleaning procedure, it is worth identifying the cause of the contamination. This will help you quickly choose the most effective cleaning method.

• If your favorite ring gets dirty and sticky, there is a huge choice of cleaning methods. The main thing is to carry out all manipulations as carefully as possible, do not use abrasive cleaning products.
• If the white surface turns yellow, the situation is worse. Yellow color is a signal that the rhodium plating has worn off. Only a master jeweler can correct the situation.
• The jewel turned black. Polishing can eliminate this drawback. It is also better to entrust this procedure to an experienced craftsman in a jewelry workshop.

What is the difficulty of care?

Cleaning objects made of this noble metal requires special care and precision. The thing is that the white surface is nothing more than yellow gold coated with a thin layer of rhodium.

It is what enhances the noble pearl shade, shine, and makes your favorite piece of jewelry more durable.

Despite all the positive aspects, it is worth remembering the rule that the rhodium layer wears off very quickly. Such products are cleaned only as a last resort if they have lost their original shine, become sticky, or changed shade.

If you know a jewelry maker, entrust this work to him. An experienced specialist knows how to handle such things so as not to damage the thin rhodium layer.

If you don't have a jeweler, you'll have to do the cleaning yourself. The main thing is to be careful and not to rush, and clear instructions on how to do this will help. So, let's begin.

How to clean gold at home

• Like any hard surface, gold is very convenient to clean with toothpaste. It will perfectly remove dirt and polish the top layer.

Attention: the paste for cleaning this type of noble metal must have a soft, gel structure, without abrasive particles. You should also give up brushes. It is better to give preference to a soft cloth.

• Prepare a mixture of ammonia and water (1:1 ratio). After placing your favorite trinkets in this liquid, leave it there for at least thirty minutes. Then wash them and place them on a towel to dry.
• Baking soda will help remove dirt very quickly. It must be used in the following way. Pour water into a small bowl and boil it. Add a spoonful of baking soda to boiling water and place your favorite ring, earrings or chain in it. After just fifteen minutes, the product should be taken out and washed.

Under no circumstances should you rub the pearly white layer with dry baking soda powder.

• Regular laundry soap will also help remove dirt. It is grated on a fine grater and mixed with liquid to form a paste-like slurry. The gold jewelry is placed in the resulting mixture and left for sixty minutes. Afterwards it is taken out, washed and dried.
• If the contamination is not significant, sugar water will help restore its beauty. To prepare it, mix water (200 ml) and sugar (dessert spoon). The gold item is dipped into the prepared solution for at least an hour.
• Mix a spoonful of dishwashing detergent and half a liter of water in a single container. The liquid should be allowed to boil a little, after which the jewelry is placed in it.
• In a similar way, use a mixture of liquid soap, hydrogen peroxide, ammonia, and water. All ingredients are mixed at the rate of 200 ml of liquid and a teaspoon of all other components. The immersion time required to remove contamination is thirty minutes.
• Table salt mixed with liquid will quickly clean your ring.

Attention: if all of the above methods do not help, you can look for a special paste for cleaning jewelry in the store (or from a jeweler you know). It will definitely cope with any contamination.

How to properly clean gemstone jewelry

Dirt deposits not only settle on the gold surface, but also become firmly lodged between the precious stones. Cleaning out such dirt is a difficult task and requires patience, as well as certain skills.

When working with precious metals, do not use sharp, hard objects. They easily scratch the setting of stones.

The following information will also be helpful:

• Do not rub the stones unless they are secured. Otherwise, there is a risk that the gem will simply fall off;
• Never clean stones with powder or abrasive paste. Regular gasoline can easily remove complex contaminants;
• If the stone has a hardness level below 5, it can only be cleaned using a soap solution.

Low hardness stones include turquoise, apatite, malachite, and moonstone.

A few traditional methods

There are several rather unusual, but as practice has shown, effective methods of cleaning precious metal. Here are some of them:

• Regular women's lipstick will help clean gold jewelry. The thing is that it contains titanium dioxide, which copes well with any contamination. Recommendation: apply lipstick not to the jewelry, but to a cotton pad, which is used to wipe the contaminated areas;
• Onions are useful not only in the kitchen, but also when peeling gold. It is rubbed, and the resulting gruel is used to wipe the contaminated areas;
• Another non-standard method of cleaning using lime. It is thoroughly ground in a porcelain bowl, gradually adding water. The result should be a mass reminiscent of sour cream. Then add a little salt and soda. The resulting mixture is left to brew for several days, after which you can begin to work. The products are placed in the prepared mixture and left in this form for several hours. In just two hours, your favorite rings, earrings, and chains will shine like new.

A few tips and cautions

As practice has shown, it is not so difficult to clean gold with your own hands. But to make the work go quickly, it’s worth remembering some secrets:

• When cleaning gold jewelry with your own hands, you should not use abrasive products: powders, gels and fabrics with hard particles.

When choosing a brush for working with precious metals and stones, give preference to options with soft bristles.

• When polishing the golden layer, do not use liquids containing chlorine. Special products will help soften hard chlorinated water.
• Before you begin the cleaning procedure, it is important to check your jewelry for damage to the clasp and other important connections. Pay attention to loose stones, damaged pendants, check clasps and hooks. There is a risk that when cleaning a damaged product, you may lose some of its parts.
• After the process is completed, the jewelry must be thoroughly rinsed under clean running water (preferably distilled) and then dried and polished with a soft microfiber cloth.

Is it possible to restore scratched and tarnished gold?

Has your favorite ring lost its shine or has unsightly scratches appeared on it? A master jeweler can solve this problem by using the method of polishing the rhodium coating.

This process is delicate, requiring experience and utmost attention. You should not polish it yourself, so as not to completely ruin your favorite item. Trust the professionals.

Knowing how to clean this noble metal at home will help not only quickly restore your jewelry to its original shine, but also protect it from scratches and other damage.

How to properly store the product

You can preserve the original appearance of the jewelry by following simple storage rules:

1. Before hiding treasures from prying eyes, pack it in a separate box.
2. Keep rings and earrings away from acid and chlorine. This means that before visiting the pool (the water in it is highly chlorinated), while washing dishes and other cleaning around the house, it is better to remove jewelry.
3. Even with very careful handling of jewelry, over time you begin to notice that the top layer wears off. Important: such jewelry must be worn extremely carefully, avoiding mechanical damage and active friction. When the top layer begins to turn yellow, it must be taken to a jeweler for galvanic treatment.

The gold surface cannot come into contact with other metals for a long time. This can cause it to change its color.

By following all the rules and recommendations of specialists in cleaning white gold jewelry, your rings, earrings and chains will last for decades, while maintaining their original appearance.
