What Jewelry Does Not Tarnish: Rhodium Plated Jewelry

When your silver or gold jewelry tarnishes, you can usually have them re-plated with the jewelers’ guarantee. Gold and silver jewelry can change color and you can have polishing or plating again at the store you bought, even because of this warranty service, the prices are higher. Our topic here is the bijouterie class of jewelry. So which jewelry does not tarnish?

In the past, bijouterie jewelry would necessarily tarnish, or jewelry that did not tarnish were only sold by famous brands in the world and would be very expensive. With technology, this situation has disappeared. Our jewelry doesn’t tarnish anymore. Its secret is rhodium plating. Rhodium is a non-corroding metal. This metal used in mining has enabled us to obtain jewelry that does not tarnish with the development of the need and technology in the jewelry industry. In other words, the feature we are looking for is that the jewelry is rhodium plated.

Rhodium plating adds the feature of not tarnishing and abrasion to the material it covers. The reason why world-famous jewelry brands that do not tarnish but are not silver or gold are expensive is their brand value. With the widespread use of rhodium plating, it is possible to reach more affordable prices for this kind of jewelry that does not darken.

Another feature of rhodium plating is that it is antiallergic. Women with sensitive skin know very well the annoyance of not having the jewelry that they love and that are affordable. They always have to use gold or silver, but rhodium plating has largely eliminated this complaint. Mostly we mean because if this disease is very severe, sometimes even the gold mine can cause allergies. For this reason, if you are not very sensitive, rhodium-plated jewelry will not cause allergies.

Since the material that causes allergies is in the jewelry mine itself (copper or nickel…), rhodium-plated jewelry creates a barrier between the metal and your skin. If you need more technical and chemical details, I recommend you to read the article in detail. When buying jewelry, ask about the coating, if you get the answer with rhodium plating, you can use it safely. Of course, until a brand new technology emerges in the jewelry industry.

Rhodium Plated Jewelry Does Not Tarnish

Rhodium plating is a common process that provides a glossy reflective look used with jewelry to increase the scratch resistance of the surface. But what is rhodium? Under what conditions is this procedure used and what should the consumer think of the cost, the average life of the treatment, and the rhodium itself? Read and discover everything you didn’t know you wanted to know about rhodium plating.

Rhodium, with atomic number 45 on the periodic table, is a rare metal that is silver-white in color. Rhodium is 10 times more expensive than gold, which raises the reason why rhodium is only used for plating rather than a base metal for a piece of jewelry. The answer to this is another distinctive feature of the item – it is extremely fragile.

The most common purpose of rhodium plating is to increase a “white” gold jewelry piece to improve coloration and provide an additional layer of protection against damage. The reason why rhodium is paired with white gold is simple: White gold doesn’t actually exist. White gold is nothing more than gold mixed with another metal that is white cast (usually silver, palladium, or nickel). This gives the final product a slightly yellow tint. Rhodium is used as the coating material to add that extra shine to the receiver of white gold to achieve a brighter shine.

However, apart from its splendid reflectivity, rhodium has protective properties that make it functionally useful as a coating metal. Rhodium never decolors or tarnishes. Besides that, it is a harder metal than gold, which means it is more scratch-resistant and can be better protected from daily wear challenges. Rhodium is also sometimes used on silver (often for its scratch-resistant properties) and platinum (to enhance shine).

One downside of rhodium plating is that it won’t last forever. The metal will eventually wear out and will require repetition. The life of rhodium plating varies but depends on a number of factors, including the primary use of the part (frequent use, contact with the elements, or prolonged contact with the skin will increase wear) and the original thickness of the coating. It’s a good idea to consider spending the extra to make thicker coatings on items used every day.

Before buying silver, platinum, or white gold jewelry, look for the rhodium plating to accurately calculate the cost of ownership. While it may be a shock to realize that the precious color and sparkling piece of white gold is actually rhodium, it would be better to understand this information right now rather than learning it first, of course, at the jeweler. It must be accompanied by a bill to repeat.

General Information on Rhodium Plated Jewelry

Let’s start with the answer to the question of what rhodium plating means. It is an action performed on silver or other metals for protection and a beautiful appearance. Rhodium is a blue-white metal. Its feature is that it remains bright under all conditions. It is known as a completely non-corrosive metal in the mining industry. Rhodium is the most expensive and precious of metals after gold and platinum.

Rhodium never tarnishes or corrodes when processed. It is resistant to acid and different weather conditions. In contact with water, in contact with oxygen, it makes silver jewelry much stronger against tarnishing. Today, with the advancement of technology and the search for changes in the jewelry industry, its use in jewelry such as gold, white gold, and silver has become widespread. Rhodium-plated necklaces and rings are among the most popular models.

After the grinding process is applied to the surface of silver and gold jewelry, a more aesthetic appearance is obtained in jewelry. With the grinding process, various colors can be obtained, whether in silver jewelry or gold jewelry, and new colors can be added to the jewelry. If it is desired to have a single color as a color, the general running-in process is applied. However, if it is to be partially colored or if there will be a pattern, the pencil grinding technique is used.

Of course, the surface to be applied before running-in is polished and washed in a special machine. Afterward, the process is terminated by grinding. Plating is the coating made on the surface of jewelry such as silver and gold for decoration or protection. Since rhodium is a metal that does not tarnish and corrode due to its structure, it is widely used in coating production. In other words, the conclusion we will clearly draw here is that this coating is made for the protection of silver jewelry and to remain bright.

The most important purpose of rhodium plating on silver metal is to prevent it from tarnishing. No rhodium-plated silver jewelry will darken. It does not cause allergies. However, uncoated silver jewelry darkens over time. Since this is an annoying and troublesome job, the products are coated. Rhodium is an expensive element. So it is only applied to jewelry as a very thin plate.

If the plated silver jewelry is not exposed to excessive friction and abrasion, it will maintain its first-day appearance for a very long time. Plated silver jewelry resembles white gold jewelry. Because this coating is also applied to white gold jewelry. Rhodium-plated products on silver have the same appearance as white gold products and provide a great advantage over gold jewelry in terms of price.

We get a lot of questions such as if the rhodium-plated necklace darkens. I think it is necessary to make an explanation on this subject. Jewelry coated with rhodium hardly shows the tarnishing effect, it may occur due to the aging of the coating as a result of the abuse of the jewelry, otherwise, there will be no negative effects.

The most commonly used method in coating applications is the electroplating process. The silver jewelry is immersed in a heated bath of Rhodium solution and an electric current is passed through the bath. This process causes Rhodium from the solution to permanently adhere to the silver jewelry surface. It is necessary to know that the coating will not last forever. Rhodium metal, which is almost the same as silver, is not reflected in jewelry prices as it is coated in small amounts on jewelry. But it should be known that the value of rhodium is almost as much as silver.

Silver Jewelry: Tarnishing and Plating

It is quite natural for a real silver to tarnish. Our silver accessories, which we buy with love and admiration, start to tarnish day by day or where they stand. The silver jewelry that we bought for the first time, shining brightly and impressing us, becomes dark after a while and becomes a trace of its original state. As it is known, silver comes first among the most used mines in jewelry making after gold.

Everyone who owns silver jewelry knows that when you first buy, the dazzling silver starts to tarnish and turn a dark color over time. Silver darkening causes no trace of the jewelry from its original state. So why does silver tarnish? Let’s look at the answer to this question. Silver, which is used most intensely after gold in jewelry making, is extracted from nature as a thousand carat. It is very difficult to process and shape the silver in this way it is extracted.

For this reason, it is mixed with materials such as copper and alloys in order to facilitate its processing and make it easier to design. These substances are actually the reason for the darkening of the silver. Silver darkening occurs due to the materials used for the easy processing of silver. Silver is a metal that is suitable for darkening due to its structure. The answer to the question of why silver does tarnish is actually the sulfur and hydrogen in the air.

Sulfur is abundant in the world. Silver also has vulnerability to sulfur, and silver begins to darken even with the slightest sulfur odor. 925 sterling silver is formed after the mines used to facilitate the processing of silver. The fact that silver reflects the light well and is flashy has always attracted the attention of people. For this reason, silver accessories, which are widely preferred in jewelry making, take their place in the showcases with their beauty.

Many products with chemical content – especially sulphate-weighted – cause the silver material to darken very early. Sulfate, on the other hand, is considered a protective and in most cases dangerous product, which is included in many cosmetic products. This substance, which is found in excess in products such as soap and shampoo, causes a negative result as a result of direct contact with silver. In addition, products such as perfumes and deodorants are risky products for silver.

The clean air issue is now an issue to be examined under the heading of “for what, by whom”. It is almost impossible to argue that the air we breathe is pure oxygen in cities with a heterogeneous structure. These harmful elements in the air, on the other hand, are harmful to silver. Being in the same areas with many people in daily life and in crowded areas where it is very difficult to be isolated, the substances that get into the air directly interact with silver and cause it to darken.

Sweat is a liquid with high acidic value. If the acid ratio is high in fluids with a pH effect, silver will be adversely affected by this situation. When silver jewelry is not in use, it should be stored specifically as food. Humid environments cause serious damage to the silver substance. Humid and steamy rooms cause a very bad effect. When not in use, silver should be stored in a dry, clean and airy area.

There are many reasons why silver may tarnish. Silver, which is affected by air bubbles, has a delicate structure. Although it is suggested that materials such as lemon, vinegar, and baking soda will be used to polish silver in a home environment, these can further damage the silver. It would be a better choice to take advantage of products that are specially produced to shine silver.

Rhodium Plated Silver

Rhodium-plated silver jewelry has emerged as a solution to the problems of silver, such as wear and color fading over time. The resistance of Rhodium can be added to the silver jewelry by the plating method. Rhodium is a white shiny metal, its reflectivity is 80% that of Ag and is superior to Ag’s in ultraviolet rays. Unlike rhodium, the surface of Ag becomes cloudy as Ag is formed. Rhodium, on the other hand, is absolutely intact.

This metal is successfully used in the reflective industry and its melting temperature is 1966 ° C. Rhodium baths contain sulfuric and phosphoric acid. Extremely good results are obtained with both. Usually, the metal content per liter is between 2 and 2.5g. For convenience, concentrated rhodium salt, phosphate, or sulfate is used, it is mixed with water, and acid is added.

Its penetrating power is very high, approaching gold and silver from this angle. In a few seconds, a white shiny layer emerges. However, it is not recommended to directly coat Ag with Rh. The rhodium layer is so thin that it cannot prevent Ag degradation. Also, the direct rhodium plating process may not be successful. For this purpose, a bright nickel coating process is applied between Ag and Rh.

Since rhodium is completely resistant to weather, it allows metals to remain bright for a long time by being galvanized. It also creates resistance against abrasion. It is not affected by any acids, including rhodium royal water. However, it can melt in sulfuric acid in hot form. Chloride is formed when gaseous chlorine is brought into contact with the heated metal.

Alternatively, it is heated with concentrated acid and sodium chloride in closed tubes of 125-150 ° C. As with all metals, the more powder the Rh is, the easier it goes into the solution. When heated in contact with air, it starts to oxidize at 300 ° C, accelerates as the temperature increases, evaporates between 900-1300 ° C. When a rhodium-plated object is heated, the underlying metal is affected when Rh is porous and thin.

Rhodium is used as a finely powdered catalyst in jewelry making due to its corrosion resistance and brilliance, in making electrical contacts due to its low degree of corrosion resistance to electricity, and in the production of tools that require high temperatures such as fiber, furnace windings, as platinum and palladium alloys have very hard properties.

An Alternative Option That Does Not Tarnish: Steel Jewelry

The most important feature of steel jewelry that distinguishes it from others is its durability, hardness, and durability, as well as its non-tarnishing structure. It does not darken.

What Can Be Done to Prevent the Jewelry From Tarnishing?

The jewelry we use on a daily basis, no matter what material it is made of, always tarnishes over time as it touches our skin. Although we prefer to go directly to the silversmith or jeweler for the darkened jewelry in the first place, sometimes we may not have time. For this, it will be useful to evaluate the possibilities at home both to prevent the jewelry from tarnishing and to restore the tarnished jewelry. I will talk about the methods I know and tried to help you with this.

What can we do to prevent the necklaces from tarnishing?

  • As you know, necklaces are jewelry that we use in the area up to the neck. Regardless of silver, gold, or imitation, the things we can do to prevent the necklaces that we wear around the neck from tarnishing are as follows:
  • Before or after wearing the necklace, never spray perfume, cologne, deodorant, and, if possible, even water on the neck area. Because these liquid materials make the necklace easier to tarnish and even rust. Since the event that we call darkening is oxidation, the oxidation state starts at the moment of contact with the liquid.

  • If you have a sweaty body, especially in the summer, be careful not to wear a necklace whenever possible. Because when we sweat, both the salt of the sweat and the liquid that comes out causes the necklace to darken. If you wear simple necklaces that are sold as a coating, it may even leave a stain on your skin as it darkens.
  • We should pay attention to some things so that the necklaces do not darken not only while wearing them but also while keeping them. You should pay attention that the areas where the necklace is stored are not damp, and if you are going to process the necklaces such as washing, you should definitely dry them afterward.

What can we do to prevent the earrings from tarnishing?

  • Although it is not possible to forget the necklace while carrying it around our neck, the earrings can remain in our ears constantly. As a result, we can cause earrings to darken more quickly. So what can we do to prevent the earrings from darkening? I’m telling…
  • In order not to darken the earrings, we should definitely avoid liquid contact first. Whether gold, silver, or imitation, earrings easily oxidize and darken with liquid contact, as in all types of jewelry.
  • With earrings, you can prevent them from darkening by not going to the bathroom, sea, or pool. If you forgot the earrings in your ears, you should immediately dry them and intervene.
  • Since we sweat a lot during the hot summer months, the earrings may become oxidized. For this, I recommend that you make it rare to wear earrings in summer.
  • We know that perfumes are also sprayed on areas such as behind the ears, and neck to keep them more permanent. Naturally, necklaces and earrings can tarnish quickly due to perfume, deodorant, or makeup. The way to prevent this is of course not to apply these materials to the areas where the earrings are.

What can be done to prevent gold-colored jewelry from tarnishing?

  • Unlike gold and silver jewelry, there is also gold-colored jewelry in the imitation jewelry market. Their tarnishing is not darkening like the oxidation we know, but rather in the form of pinking/discoloring. Of course, we can do something to prevent gold-colored jewelry from tarnishing:
  • As I mentioned above, we should definitely avoid liquid contact.
  • Especially when we wear gold-colored imitation jewelry in summer, we can see that that jewelry turns pink on the same day. To prevent this, of course, we should not wear jewelry, even knowing that we will sweat.
  • No matter how well we preserve it, gold-colored jewelry, ie imitation coatings, have a certain lifespan and can darken by itself. To prevent this, you can put your jewelry in a breathable cotton cloth or small bag. Thus, it will not remain moist and the oxidation period will be prolonged by not being in excessive contact with air.
