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.
Why white gold may turn yellow
A white gold bracelet or chain has turned yellow - the question immediately arises: why? There are several reasons for the appearance of a yellowish tint:
- We wear and sweat for a long time. Rarely does anyone think about this, but human sweat is saturated with various salts and acids. When interacting with metals, it is a good reagent. If a person sweats frequently, his precious metal jewelry will turn yellow. It is recommended not to wear jewelry during hot weather or during excessive physical activity. Another reason for sweating is hormonal imbalance. Adolescents and women during pregnancy, breastfeeding and menopause may sweat profusely. Sweating may be a result of your body eliminating medications you are taking. In all these cases, wearing gold jewelry is not recommended.
- Rhodium has expired. Although rhodium plating is a reliable process, it is short-lived. As a result of friction with the skin, the rhodium can wear off. Therefore, after 3-5 years, it is recommended that gold items be rhodium-plated again.
- Mechanical damage. Gold jewelry cannot be constantly ground and polished, especially on your own. These actions lead to yellowing of the jewelry, as well as scratches on it.
- Cleaning with abrasives. At home, when cleaning gold, substances such as salt and soda are often used. They really effectively clean products from dirt and restore their former shine, but they do it indelicately. Salt and soda may leave scratches.
Top 3 gold cleaning methods
There are basic cleaning rules that warn product owners against the danger of damaging the jewelry. It is worth listening to the following recommendations. They help you understand how to clean white gold with diamonds, precious stones, and tarnished items.
- You should not rub the stones when cleaning; as a rule, they are not firmly attached to the product. Only the metal itself is cleaned, without touching the precious stones.
- If the stone itself is contaminated, you should rinse it carefully under running water. If this does not help, then leave the decoration in soda water for 15 minutes.
- Gasoline will help save a product with precious stones from complex contamination. Toothpastes should not be used.
- When cleaning with toothpaste when the jewelry has become dull, do not use toothpaste with chlorine. This may damage the surface layer of the product.
- It is better to wash darkened white gold with laundry or liquid soap. You can use a special solution for these purposes, which is sold in any jewelry store.

When cleaning white gold, do not rub the stones.
There are several reasons why the chain on the neck darkens and oxidizes:
- cosmetics: milk, creams, powders, etc.;
- perfume or eau de toilette;
- skin features.
The last reason is the most common. There are hundreds of thousands of sweat-removing pores on the human body, which are responsible for thermoregulation and natural metabolism in the body. The more often an alloyed precious metal is exposed to sweat, the faster it oxidizes. Therefore, the same product serves one owner for a long time and quickly becomes dark for another.
According to another version, gold serves as an indicator of health problems. It is believed that jewelry made from this noble metal oxidizes and darkens if its owner has kidney or liver problems.
Medical gold
Signs that jewelry is oxidizing cannot be missed. But there are several ways that will help you safely return the product to its original appearance at home.
The main ones:
- Cleaning with ammonia. The most common and easiest way. You will need a deep glass container into which you pour a glass of water. To make the powder dissolve better, use warm, but not hot, water. Pour a tablespoon of washing powder or liquid soap and a teaspoon of ammonia into the container. The sequence must be maintained: first the powder, and then the ammonia solution. Decorations are immersed in the resulting mixture for two hours. After this, they are washed with warm running water and dried with a soft waffle towel.
- Dishwashing liquid. Pour a glass of water into a small saucepan or stewpan, add a teaspoon of the product, place a soft cloth on the bottom and place things that have begun to oxidize on it. Boil soapy water together with jewelry for 7-10 minutes, then rinse and dry the jewelry.
- Liquid soap, ammonia and peroxide. Another effective mixture that allows you to quickly and effectively get rid of dirty deposits on jewelry at home. Dissolve a teaspoon of ammonia, soap and peroxide in a glass of warm water. It is enough to place the jewelry in the resulting solution for just 10 minutes. After this, the products are washed and dried.
Unfortunately, there is no way to prevent your favorite ring or chain from oxidizing.
Take a piece of flannel, fleece, or any soft cloth, and then lightly wipe the item with it. The method is great for rings and earrings. By doing this procedure every day, you will not only save time on cleaning, but also extend the life of the products.
Most effective
In addition to ammonia mixtures, effective ones include specialized devices for home cleaning of oxidizing jewelry and costume jewelry. These are ultrasonic devices, effervescent tablets, special impregnations and wipes. However, when choosing impregnation, you need to pay attention to what kind of gold it is suitable for.
The cheapest
If it is not possible to look for specialized means or take jewelry to a workshop, use available means. In addition to the well-known soda, salt and vinegar, Coca-Cola is used, which also contains acids that break down plaque. The products are soaked in a glass of drink for one hour, and then washed with running water and wiped with a cloth.
When cleaning products made of precious metals, you need to pay attention not only to the composition, but also to the inlay, as well as the style of execution. For example, pearls, turquoise, and corals cannot be cleaned using ammonia. But diamonds from ammonia, on the contrary, will shine with renewed vigor.
Expert opinion
Vsevolod Kozlovsky
6 years in jewelry making. Knows everything about samples and can identify a fake in 12 seconds
Airy weaves and overly intricate patterns should not be wiped or polished yourself. Even with the use of alloys, gold remains quite soft and breaks quickly.
Do not use brushes on white gold or gold-plated items. Even the softest bristles can damage the coating and cause the item to begin to oxidize. But it is best to initially choose jewelry that suits your lifestyle.
If you are used to leading an active lifestyle and do not like spending time on cleaning and polishing jewelry, then you should choose exclusively 750 gold. Let these be simple forms with simple inlay or even without it. Such products require virtually no maintenance, oxidize little and are easy to clean if necessary.
The 750 test is worth paying attention to for people with a slow metabolism and profuse sweating. The fewer impurities in the alloy, the longer the decoration will retain its attractive appearance.
Any non-precious alloys, jewelry or gold plating lose their attractiveness over time and oxidize under the influence of the environment. However, with proper care, such products can please the owner for many years.
In addition, it is worth paying attention to jewelry made of metals such as titanium. Under the influence of high temperature and various reagents, it oxidizes, acquiring all kinds of shades, including yellow. Products made from it look very elegant and last longer than sprayed jewelry.
We suggest you familiarize yourself with How to clean a metal door
Products made of brass and bronze look no less attractive. They are easy to use and look stylish in combination with your everyday wardrobe. The main rule for caring for such jewelry is timely cleaning of dirt.
The invulnerability of gold to acids and alkalis does not mean that you can wear precious jewelry without restrictions. If you want to keep the products for a long time, you do not need to wear
- decorations:
- during cleaning;
- when visiting cosmetic procedures and health centers;
- immediately after using creams, perfumes and applying cosmetics.
Every time you remove jewelry in the evening, wipe it with flannel, and remove dirt from hard-to-reach places with a cotton swab. Under no circumstances should cotton wool be soaked in peroxide or acetone. This will not give an effect, but the product may oxidize from such exposure. And be sure to store your jewelry properly.
The resting period for jewelry is no less important. Anything that the precious metal touches can damage it. Therefore, it is advisable to store jewelry in boxes with soft upholstery and separate sections. If there is no such box, it can be replaced with any box that does not allow sunlight to pass through, and the products themselves can be wrapped in flannel.
How to return whiteness to a product, what to do, methods of prevention
It is easier to prevent any problem than to eliminate the consequences. To prevent white gold from turning yellow, you need to store it properly and take care of it in a timely manner. Simple preventive measures can help maintain noble whiteness:
- All existing jewelry must be stored separately. White gold in one container, classic yellow in another. Silver, precious stones and jewelry are stored separately. You can keep jewelry in their original boxes. You can purchase special cabinets for jewelry.
- It is necessary to prevent the decoration from coming into contact with chemicals. If your hands are treated with cream, the rings from your fingers must be removed. All jewelry is removed during water procedures, when swimming in pools and reservoirs, when visiting baths and saunas. If the house is cleaned using detergents and cleaning products, then this should also be done without jewelry.
- It is not recommended to polish gold items yourself. The damaged structure of a ring or bracelet is almost impossible to restore. It's better to trust the jeweler. A specialist will polish the precious metal using special tools and products. Taking a gold ring to a jeweler for polishing is much cheaper than buying a new one later.
As you can see, caring for white gold is quite simple. Timely preventive measures will extend the life of gold jewelry for many years.
Care and storage rules
In order for jewelry to please its owner for a long time, it is necessary to properly care for and store it. Advice from jewelers will help.
- Keep rings, earrings, crosses, chains and other jewelry away from chlorine and water to prevent oxidation.
- Each individual piece of jewelry must be stored in an individual box or casket with dividers.
- You should not wear white gold jewelry on a regular basis, especially if it is created using rhodium.
- During contact with water, it is better to remove jewelry.
- You should avoid situations in which the product is injured (cutting, cleaning around the house, etc.).
Methods for professional restoration of gold whiteness
Gold bleaching is a common process in jewelry making.

Galvanization: Rhodium treatment by current and electrolysis process
Galvanization in simple words is gilding. If you have heard the term “plated gold”, we are talking about gold-plated products. The galvanization process is used to a greater extent to enhance the positive characteristics of the noble metal. Rhodium galvanization is carried out - the application of a metal that looks like silver using an electric current. How this process happens:
- the bath is filled with rhodium solution;
- a cleaned piece of jewelry is placed into the solution;
- Electric current is passed through electrodes;
- When exposed to electricity, rhodium deposits on the gold item.
Electroplated gold acquires a noble color and shine, becomes durable, heat-resistant, resistant to corrosion and oxidation.
Rhodium plating jewelry
Immersion in rhodium solution as a cheaper method
Rhodium belongs to the platinum group and is much more expensive than noble metals. Rhodium is valued at 10 times higher than gold. Plating is often done by immersing gold jewelry in a rhodium solution, which is cheaper
The rhodium plating service costs from 1,500 thousand rubles and above. Jewelers guarantee the safety of gold jewelry: earrings coated with rhodium will last about 10 years, chains - 6 years, rings - 3 years.
Wear time depends on how often the jewelry is worn and comes into contact with the skin.
Why does the finger under the wedding ring turn black?
At a time when people believed in omens, seeing a black mark from a ring was considered a very bad sign. Today no one believes in such signs, and the blackness is explained by the simple desire of jewelry stores to give their goods a more attractive appearance. For this purpose, products (especially rings) are rubbed with a special polishing paste.
It is this that remains on the skin over time in the form of dark spots, and there is no talk of gold oxidizing.
Unfortunately, it is impossible to correct the laws of physics: alloying metals oxidize. There are only two ways out of this situation: timely coating of gold with appropriate sputtering or choosing samples of classical alloys with a low content of impurities.
What should not be cleaned, according to the recommendations of jewelers
If you decide to clean gold jewelry yourself at home, you need to know that not all substances are suitable for cleaning this metal.
Dangerous ammonia
Ammonia is an indispensable assistant in the arsenal of housewives. It is used to clean absolutely everything: from clothes to gold items. But, according to jewelers, ammonia is also harmful to gold plating.
You cannot clean white and regular gold using the same solution at once. You should also not clean gold and silver together.
Ionization occurs and, in simple terms, the jewelry changes colors with each other. Gold unprotected by other coatings can react with ammonia, causing it to darken. Instead of pure ammonia, it is recommended to use an ammonia solution - a solvent solvent - to clean gold jewelry.
Folk remedies for cleaning white gold using dishwashing detergent
There are many folk remedies that can help clean white gold if it has turned yellow. The most common of these products is dishwashing gel, which every housewife uses. Detergents are used to remove dirt of varying degrees, both separately and together with other substances.
Dishwashing detergent solution
Popular recipes for using dishwashing detergent:
- Pour a teaspoon of washing gel into a glass of water. Pour the solution into a saucepan, having previously covered the bottom with a soft cloth. Place jewelry on a cloth. Boil the contents of the saucepan for 10 minutes.
- Make a solution from a glass of water, a teaspoon of detergent, a teaspoon of ammonia, 40 mg of hydrogen peroxide. White gold should be kept in the resulting solution for 20-25 minutes, depending on the degree of contamination.
- Another type of cleaning solution is made by mixing a glass of warm water, a teaspoon of washing gel, and 2 teaspoons of hyposulfite pharmaceutical product. You need to keep the jewelry in the solution for 20 minutes.
How to clean the product at home?
The most effective method for cleaning metal can be determined by determining the cause of tarnishing and contamination of the jewelry. Do not self-clean if the product has turned black or yellowed. In the first situation, the gold must be polished with a special device; in the second, a yellow tint indicates that the surface layer has been erased. Only a jeweler can restore it well. You can clean metal if there is surface contamination or stickiness.
There are many methods for cleaning white gold at home. You should only choose those that do not require rough treatment of metal. It is worth cleaning jewelry with rhodium and alloys only in special situations, since with frequent cleaning it can quickly deplete, turn yellow and require qualified assistance.
Toothpaste
This is a traditional method for cleaning many products. Toothpaste should be chosen so that it does not have inclusions. They can damage and scratch products. The consistency of the paste should be gel. To clean metal, you must:
- take a chain, bracelet, ring or pendant made of white gold in your hands so that the product cannot fall;
- Under no circumstances should you clean the jewelry above the sink or in the bathroom; if it falls, it may end up in the sewer;
- apply a little toothpaste to a cloth or soft sponge (sometimes people use melamine sponges, but this should not be done);
- Gently, without harshness, rub the product in contaminated areas.
Toothpaste – a means for cleaning white gold
After the procedure, you need to rinse the jewelry under running cold water, dry it with a towel and place it on it to dry. You cannot clean jewelry with toothpaste if it is plated with rhodium. This method is only suitable for metal alloys.
Sometimes people do not finish reading the information and immediately begin to act. This is the case when you can ruin the jewelry forever or have to take it to a jeweler for restoration. The soda method is considered the most inexpensive and fastest. To clean white metal with soda, you need to pour a glass of boiled water and add 1 teaspoon of soda.
Ammonia alcohol

Ammonia is mixed with water in equal proportions. You will need no more than a glass for cleaning. It is necessary to place the product in prepared water with liquid. The cleaning time is determined depending on the degree of contamination. Strong - leave the decoration for 1-2 hours, small - for half an hour. Afterwards, you should also rinse the product under running water and leave to dry on a napkin or towel.
Among the various methods, there is the usual cleaning with laundry soap. It will help with lightly soiled jewelry.

Why does white gold turn yellow on my finger?
Expert opinion

First, you need to understand that it is not the metal that turns yellow, but the surface of the product. Yellowness is associated with external influences. This can be oxidation as a result of the reaction of the metal with human sweat, chemical elements in creams, perfumes, and hygiene products. Yellowness can be an accumulated coating of dirt, dust, or the result of the interaction of metals in the ligature. Each case is individual.

We need to figure out what is the reason for the yellowness that appears. Analyze your health status: are your hormonal levels disrupted, are you taking medications. In other cases, try cleaning your jewelry at home using detergents, ammonia, salt or soda. White gold items cannot be rubbed, polished or polished. If the precious metal does not turn white, contact a jeweler.
White gold turned yellow in 2 months, how to restore it?
Expert opinion
Pribrezhny Gennady Valentinovich
Jeweler 6th category
White gold cannot turn yellow in a short period of time. Unless, of course, you are working with the soil without removing the rings. Jewelry stores provide guarantees on gold items for 2-3 years. Therefore, if white gold turns yellow 2 months after purchase, it is definitely a fake, a low-quality alloy and unreliable coating. You cannot remove yellowness on your own. There is only one way out: take the jewelry to a jeweler for re-plating.
The process of yellowing of products and restoration methods
Products made from white material are resistant to deformation and retain an attractive appearance thanks to the addition of a solid ligature.
We suggest you familiarize yourself with what paint to paint a jacket at home
For what reasons and why does white gold turn yellow? Jewelry made from different grades of material is coated with rhodium. The metal film provides the composition with additional wear resistance, hardness, and gives a silvery tint.
Many alloys contain silver, which reacts with oxygen. Over time, such a product darkens, so the surface of the product is plated with rhodium.
The essence of the method is the process of electrolysis under the influence of electric current. Jewelry coated in this way will retain its appearance for a long time.
Using the immersion method in a special solution is cheap and easy to implement. At the same time, the rhodium layer does not always cover the product evenly, and it also tends to wear off quickly.
In many cases, jewelry loses its former appearance during use, resulting in a yellowish layer of alloy being revealed under the coating. This can happen if you wear jewelry for a long time.
To ensure that jewelry remains white and maintains its original appearance for a long time, careful handling is required. When caring for products, it is not recommended to:
- use soda and aggressive substances for cleaning;
- grind and polish jewelry.
The greatest danger is perchloric acid, so it is better to take off your jewelry when going to the shower or swimming pool. This also applies to washing dishes and cleaning using detergents.
The effect of yellowing is observed on the surface of products made from a noble alloy with the addition of silver and copper. The presence of defects does not indicate a decrease in the value of the jewelry.
When storing jewelry, you need to adhere to basic rules and avoid close contact with other metals. It is not recommended to clean the tarnished surface yourself.
What to do if white gold turns yellow? To restore the previous appearance of products, it is better to contact a jewelry workshop. Experienced craftsmen restore the surface and re-treat it with rhodium.
It is advisable to clean your jewelry regularly and carefully. This will prevent the jewelry from oxidizing and will maintain its attractive appearance for a long time. But don’t be upset if the product has already turned black. Powder, detergent and even salt will help restore something dear to your heart.
If there is no need to rush, it is enough to soak oxidizing precious jewelry overnight in a solution of soda or table salt. In the morning, they are washed with warm water, lightly dried with a soft cloth and wiped with a lint-free towel.
White gold
In some cases, cleaning white gold at home is strictly prohibited or impossible. For example, yellowed jewelry can only be restored to its original appearance in a galvanic workshop. Blackened white gold is restored by polishing, but at home it is almost impossible to carefully polish the product without disturbing the plating.
If we are talking about cleaning simple stains, it is better to use one of the methods listed above. You should be careful with ammonia and soda: both methods are classified as potent.
Gold with stones
The peculiarity of the procedure will be some unacceptable actions:
- Do not boil or use brushes;
- wipe jewelry with sponges using powders;
- Do not use corrosive preparations to clean items containing pearls;
- The use of soda and vinegar is not recommended.
Otherwise, the same cleaning methods are used for inlaid jewelry as for ordinary precious items.
Gilded
Gold-plated items, like any plating jewelry, must be cleaned very carefully. Polishing work is strictly prohibited at home. Powders and toothpaste should not be used. As a rule, gold-plated items can only be washed in mild soap solutions or soaked in weak solutions of baking soda - no more than ½ teaspoon per glass of warm water.
Medical gold
Medical alloy, better known to consumers as jewelry alloy, belongs to a special category of jewelry, the cleaning of which must be carried out as carefully as possible. What you should definitely give up is chalk, tooth powder and products with large particles. All this can damage the spray.
Mild soap solutions without long soaking or boiling are best. The products are also wiped with a napkin soaked in vinegar or beer. This will return the oxidizing product to its original shine.
Jeweler's opinion
Molokanov N.M.
Jeweler, 26 years of experience in jewelry production.
The most common reason for the appearance of yellowness on white gold is poor-quality jewelry. Therefore, you need to purchase precious jewelry in jewelry stores. There is no need to be shy about asking for a certificate for decoration or asking for an examination. In all serious salons there are special devices with which you can determine the composition of the alloy. It is also recommended to buy gold jewelry of the highest standard. They will cost more, but their quality is much higher. There is no need to save on yourself. In addition, jewelry will retain its attractive appearance for a long time if you care for it correctly: - do not get carried away with cleaning with unknown means; act delicately; - regular laundry soap or dishwashing detergent works best; - if the ring or earrings have a precious stone, then rinse with regular running water or soda water. The safest thing to do is to entrust your favorite jewelry to a specialist who will return it to its whiteness using professional methods.
Causes of darkening of gold
Several years ago, ex-millionaire Sterligov claimed that the Central Bank’s 999 gold coins rusted after being in the ground. However, rust on gold is a questionable matter. But products made of gold alloys can oxidize, that is, tarnish or darken, and there are several reasons for this:
- Compound. Jewelry is not made from pure gold. For strength, alloys of different volume and composition are introduced into the alloy, which changes the physicochemical properties of the metal. The lower the grade, the higher the likelihood of rapid wear. In this case, the jewelry darkens due to the fact that the metal oxidizes.
- Iodine. As a reagent, this harmless antiseptic destroys the molecular structure of the outer layer of products. As a result, gray spots appear on the jewelry. That is why it is recommended to remove gold jewelry when visiting swimming pools and SPA treatments. Once the top layer is damaged, the products begin to oxidize.
- Chemical industry products. Cosmetics, detergents, and some medications contain substances that can adversely affect the appearance of jewelry made from precious alloys.
In addition, sweat and fat particles remain on the outer layer, onto which dirt from the environment settles over time. If oxidizing jewelry is not cleaned in a timely manner, it will appear that the gold has turned black.
