What Factors Determine the Rhodium Price? 15+ Facts

The rhodium price is one of the most important factors in determining the price of a diamond. In this article we will discuss what determines the rhodium price, so that you can make sure to get the best deal possible.

What Factors Determine the Rhodium Price?

A variety of factors influence the price at which rhodium, a popular precious metal, trades on global financial markets.

Rhodium is a commodity, a real metal that is traded across continents and through a variety of exchanges and trading platforms. Investors who comprehend how various aspects affect the price of rhodium will have a greater probability of benefiting on price increases or decreases for this type of metal commodity.

What Factors Determine the Rhodium Price?

As with other precious metals, when rhodium is priced per ounce, supply is a significant factor in the price shift. Historically, the largest quantities of rhodium have originated from South Africa and Russia.

Investors continue to monitor any increases in rhodium stockpiles or disruptions in rhodium supply in an effort to forecast rhodium market price movements. This precious metal’s demand is a significant factor in rhodium’s price. Rhodium is utilized in a variety of technologies, including aircraft design, as well as jewelry.

In addition, it is utilized in the catalytic converter of a car, alongside other valuable metals such as palladium. The “demand for catalytic converters” can cause price fluctuations in rhodium, palladium, and other comparatively rare metals.

Investors who wish to comprehend price fluctuations in rhodium will also investigate how speculation influences a large array of commodities.

Today, rhodium and other precious metals serve as the underlying asset for a plethora of mutual funds, exchange-traded funds, and other investment vehicles that occasionally offer feedback on the general price of precious metals.

This indicates that speculation is having a greater impact on commodity prices, resulting in a great deal more volatility for components such as rhodium.

Traders seek to profit from rhodium and other precious metals in part by spotting overall market trends. Even while precious metals have relatively constant values, i.e., physical values per ounce, market movements might affect the price that purchasers are ready to pay for this item.

Currently, investors are “timing the market” for commodities similarly to how they time the market for stocks, since new fund options allow them to “get in and out” of precious metals swiftly.

All of this is crucial for comprehending how investors view rhodium and other precious metals, not only as items employed in consumer or industrial products, but as abstract moneymakers whose value can fluctuate substantially.

What is rhodium?

Initially, rhodium is a rare and valuable material that is 10 to 25 times more expensive than gold. Rhodium is silver-colored, highly reflective, and does not tarnish or corrode. It is a member of the platinum group of metals. It is tougher than gold and extremely resilient.

What Factors Determine the Rhodium Price?

Rhodium is an extremely fragile metal that is difficult to mold or mould. Therefore, pure rhodium cannot be used to create jewelry. It may readily crack and shatter on its own, similar to glass. Rhodium, when used to plate other jewelry, increases the metal’s durability.

What Is Rhodium Plated?

As discussed earlier, rhodium plating is commonly used on jewelry. It is typically applied on silver and white gold to increase their endurance and add a little of luster. This technique, also known as rhodium dipping, employs electricity to attach rhodium to an existing metal.

The Right Tools for the Job

Rhodium electroplating requires many components, including rhodium, an activator, and an electrocleaner. In addition to gold or platinum wire, the method requires a platinized titanium anode and a stainless steel anode.

Chemicals and fumes necessitate the use of eye protection and ventilation to prevent injury/illness. Before being rhodium-plated, the initial item of jewelry must be immaculately clean. Even a speck of grime inhibits rhodium coating from adhering to metal.

The Rhodium Plating Process

The procedure begins with the placement of distilled water, electrocleaner, and the stainless steel anode in a beaker. In a separate beaker, activator powder and distilled water are combined. The platinized titanium anode and the rhodium bath solution are contained in a third beaker. Both beakers are heated by placing them on an electric burner.

A machine for electroplating then applies a current. The positive lead of the machine is connected to the stainless steel anode in the electrocleaner’s beaker. The negative lead clips into a gold or platinum wire with a hook, which will retain the jewelry.

This object is hung on a hook and submerged in the electrocleaner solution. This eliminates any leftover particles from the component. Before dipping the jewelry in rhodium, it is cleaned in distilled water and then immersed for a few minutes in an activator solution at room temperature.

The positive lead is linked to the anode in the rhodium bath following a second rinse of the item. The jewelry is then immersed in rhodium for a brief period of time. The procedure is completed by rinsing the object for a third time.

What is the process of rhodium plating?

Electroplating is used to platinize rhodium. Prior to plating a piece of jewelry, it must be meticulously cleaned to eliminate any impurities. The plating will not adhere if there is any dirt on the item.

Before the object is immersed in the rhodium solution, it is cleaned using distilled water, steam cleaning, and electro cleaning, among other methods. The rhodium is then welded to the base metal by applying a positive electrical charge.

The rhodium coating will become black if the electric current is too strong. Approximately one and a half hours are required to finish the procedure.

Black Rhodium Plating

Use either normal or black rhodium for rhodium dipping. This plating solution contains trace quantities of three more metal alloys: tellurium oxide, arsenic trioxide, and tin sulfate. When combined with the rhodium bath, they provide a gunmetal gray finish on jewelry, as opposed to the silvery-white sheen characteristic with rhodium plating.

Does Rhodium Tarnish?

The Science Behind Tarnishing

Simply simply, corrosion is the cause of tarnish. It is a chemical reaction that happens when certain gases or chemical substances come into contact with metals such as copper, aluminum, or brass.

Copper is a significant exception to the rule that most tarnished metal surfaces display a dull gray or black film: when exposed to oxygen, copper glows green. Depending on the type of metal, tarnish can preserve the metal under the surface, but it can also make the metal appear unsightly.

Some valuable metals can acquire a tarnished finish. The vast majority of gold jewelry is not composed of pure 24K gold, but instead comprises metal alloys for increased durability. Pure silver does not often tarnish on its own, but it is too soft to be used. Consequently, the majority of silver jewelry supplied commercially comprises 92,5% silver and 7,5% other metals, mostly copper.

Why Rhodium Does Not Tarnish

Rhodium is a unique metal. It has a Mohs hardness rating of 6 and is one of the hardest substances in existence. On the same level as titanium and just below tungsten, which ranks seventh on the scale. Diamonds have a Mohs value of 10 for reference.

The hardness of a metal does not necessarily make it a good contender for jewelry in its pure state. Rhodium is one instance. It is fragile in its natural condition, able to break almost as easily as glass. However, it is a great plating for silver and gold. In addition to its brightness, it is also more resistant to scratches.

Rhodium is a member of the platinum metals. These elements, which are clustered together on the periodic table, have several significant properties: They have higher melting temperatures and are chemically stable. They do not corrode or tarnish either.

Is Rhodium Hypoallergenic?

If you’ve ever experienced an allergic response to a piece of jewelry, it likely contains nickel. Ten to twenty percent of the human population has an allergy to nickel. This is due to the fact that their immune systems see nickel as a foreign intruder and react by causing red, irritated skin and rashes.

Combining nickel with other metals is widespread, especially in costume jewelry. This is done to strengthen the jewelry and make it less prone to bend or break.

To be hypoallergenic, an item must contain either no nickel at all or extremely minimal levels. 24K gold, sterling silver, copper, titanium, and rhodium are hypoallergenic metals and alloys.

Why should I rhodium plate my jewelry?

Rhodium plating, also known as rhodium dip or rhodium flashing, is used to enhance the durability, sheen, and light reflection of jewelry. A piece of jewelry that has been rhodium-plated will be more scratch-resistant since rhodium is a strong metal.

Rhodium plating is typically applied to metals with a silvery tone, such as white gold, palladium, and silver. The typical thickness of rhodium plating is between 0.75 and 1 microns.

How thick should the rhodium plating be?

The optimal plating thickness for rhodium is 0.75 to 1 micron. Although this may sound exceedingly tiny, it is regarded to be thick enough for rings and other jewelry that is subject to hard use.

A thickness of.10 to.50 is suitable for jewelry like as earrings and pendants that are used less frequently or in shielded environments.

Due to rhodium’s brittleness, the plating might shatter if it is too thick. However, if the rhodium plating is too thin, it might discolor the jewelry. Jewelers must verify that the plating thickness on the jewelry is optimal.

Can I rhodium plate a yellow gold piece?

Yes. To convert the hue of yellow gold to white, rhodium plating can be applied. Keep in mind, however, that when the plating wears away, the yellow tint will begin to show through. This will produce a discolored or yellowed piece of jewelry. To prevent this, the component may require plating more often.

What Factors Determine the Rhodium Price?

Should I rhodium plate sterling silver?

As a white metal, sterling silver does not require rhodium plating to attain its hue. However, it has a tendency to tarnish over time. To prevent this, silver jewelry that has been rhodium-plated will retain its luster and resist tarnishing for a long time.

As the coating deteriorates over time, the white of the silver will emerge, although it will not be as apparent as gold. These exposed portions may get some tarnish, but it is simple to remove at home.

Is rhodium plated jewelry safe to wear?

True Rhodium plating is hypoallergenic; thus, wearing rhodium plated jewelry will not induce skin sensitivities. Rhodium lacks allergens like nickel. In fact, rhodium plating can solve this issue if you have a piece of jewelry that is causing skin irritation.

Note, however, that while rhodium alone does not cause rashes, white gold alloys sometimes include nickel. As the rhodium plating wears off and the underlying metal of the jewelry comes into touch with your skin, nickel allergies may develop.

How long does rhodium plating last?

Numerous consumers consider rhodium plating to be permanent. As with any other jewelry metal, it is durable yet susceptible to wear and tear with exposure.

Over time, rhodium plating fades off and must be reapplied. Typically, a ring will need to be re-plated every 12 to 18 months, although this can vary based on the amount of wear and tear the piece endures, as well as the thickness of the plating and the color of the base metal.

Occasionally, the wearer’s physiological chemistry can also alter the rate at which plating fades off. There is a strong likelihood that the color may bleed through within the year if the base metal is yellowish.

Will rhodium plating affect gemstones?

This varies according on the gemstone. Some softer gemstones, such as peridot, pearls, opals, topaz, turquoise, and coral, as well as treated or extensively incorporated rubies and emeralds, are susceptible to damage during the procedure.

These diamonds, as well as many others, cannot withstand the sulfuric acid and heat in the electroplating solutions, and their surfaces can become spotted and pitted.

Diamonds and other hard gemstones, such as sapphires and rubies, can endure rhodium plating. They are not required to be removed before to plating the jewelry and are not harmed by the procedure.

How can I make rhodium plating last longer?

Rhodium plating will inevitably deteriorate with time, but there are ways to make it last as long as possible.

What Factors Determine the Rhodium Price?

  • Avoid touching your ring’s rhodium coating. For example, washing your hands frequently might accelerate its loss.
  • Do not expose jewelry to strong chemicals. Always remove your jewelry or wear rubber gloves while handling chemicals to safeguard your rings.
  • When swimming in extremely chlorinated pools, remove your jewelry, since the chlorine can harm the plating.
  • Additionally, perfumes and cosmetics might impact rhodium plating. Avoid contact with these substances and remove any residue if it occurs.

What is the cost of rhodium plating?

Due to the rarity and expense of rhodium, plating is rather pricey. Re-plating a white gold ring can cost up to $100, depending on the quality of the rhodium, the jeweler’s expertise, and the size of the piece.

The concern that many individuals have with rhodium plating is that it is a recurring expense that accumulates quickly. To avoid this, you may prefer to select a white, shiny metal that does not require plating, such as platinum, which is naturally white and silver-colored. Note, however, that regardless of the metal you pick, there will always be maintenance expenses.

Even platinum is susceptible to scratches and scuffs, necessitating periodic cleaning. Check out our page on white gold versus platinum, which discusses plating and polishing, for additional information.

An alternative method is to purchase from a jeweler that offers free rhodium plating maintenance. Some respectable dealers, such as James Allen, provide a lifetime guarantee that includes periodic rhodium plating procedures as needed, which can decrease your recurring re-plating expenses. However, do not forget to account for necessary delivery costs.

How do I know if my jewelry is rhodium plated?

Because white gold is not its natural hue, all white gold rings are rhodium-plated. As stated previously, white gold is yellow in its natural state. Nonetheless, it is a legal necessity for the vendor to state whether or not your jewelry has been rhodium-plated.


1. Is it illegal to use Rhodium plating over white gold jewelry and not advise the buyer about it?

Yes, it is prohibited to sell white gold plated with rhodium without informing the consumer. Regarding this, JC Penney lost a class action lawsuit.

The finest jewelry retailers will always disclose this information. Some even include little consumer-facing signs within their display case. Frequently, the consumer does not hear the salesperson’s disclosure because of the moment’s enthusiasm.

2. After years of wear my mother’s white gold wedding band still looks great. Why didn’t hers need constant re-plating like mine has?

The white alloy in your mother’s white gold ring was likely palladium, as opposed to the more frequent nickel used nowadays. Palladium white gold is chemically stable, retains a beautiful warm “gray-white” hue, and does not require rhodium plating to stay appealing or to prevent chemical deterioration.

3. I had my white gold ring re-sized and the back of the band has developed small spots on its’ surface. What is going on?

There was a significant possibility that the rhodium plating bath was contaminated with another metal, such as silver or iron.

Together with rhodium, they were deposited. Tiny spots appear on the surface of plated objects when they rust. The plating must be removed off the ring and reapplied to a clean surface using a new plating bath.

4. My white gold ring needs re-plating with rhodium about every six months. How can I make it last longer?

It must be coated with a sufficient coating of rhodium. A minimum of 30 to 40 micro-inches of consistent rhodium plating would give exceptional longevity and reduce the frequency of jewelry store visits. Some retailers ship their items to specialized plating businesses that can apply thicker coatings.

5. I just replaced my nickel white gold ring with a new palladium white gold ring and yet I am still getting a skin rash. Why is this happening?

It appears that your new ring includes nickel as well. As a whitener for white gold, nickel and palladium are frequently combined. In general, a fair balance is reached between the metal’s color and its workability. It might be a palladium-nickel alloy, as palladium alone does not create a skin rash.

6. Is it true that perfume can make rhodium wear off?

Undoubtedly, chemical exposure might contribute to the shortened lifespan of rhodium plating. However, there are several things that may be done to prevent the consequences of accidental exposure to fragrances, soaps, and chlorine. Using the proper techniques, a thick, pore-free coating of rhodium is applied to a clean surface.

What Factors Determine the Rhodium Price?

7. I want to have a yellow gold chain re-plated. How thick should the rhodium be and how long can I expect it to last?

Chains must endure sweat, cologne, and the continual mild abrasion of the links rubbing against one another as a result of the regular movement of the human body. Constantly worn, they constitute one of the greatest obstacles for a plated covering. Minimum of 40 microinches of uniform rhodium is required. The longevity is 1 to 3 years.

8. Why did my silver jewelry tarnish after being plated with rhodium?

The rhodium coating is likely too thin! Corrosive oxides are “rising” through the surface’s small pores, causing the discoloration. This form of surface tarnish will ultimately seem “yellowish” brilliant and is typically observed on jewelry items such as necklaces and bracelets.

9. The plating on my fiancee’s engagement ring wore off after 4 months. Why did it wear off so quickly?

If the ring was resized, the repair area was likely not completely cleaned prior to re-plating, or a coating of rhodium was not deposited thick enough for good long-term wear life. If the ring was cast rather than die struck, the setting may be porous, causing the rhodium plating to wear off prematurely.

10. Help! I’ve developed a skin rash from my white gold ring.

There is a remedy. If a thick coating of dense, pore-free rhodium plating is applied to the whole contact surface of the ring, even inside the curves, nickel rashes can be removed almost entirely. Because any break in the rhodium layer might expose the nickel in your white gold again, the rhodium coating must be thick.


Before opting to buy in or sell rhodium, it is essential to have a thorough understanding of the variables influencing its price. Historically, rhodium has been a volatile precious metal to invest in; thus, you need investigate the industries influencing its price to see where it may be heading in the future.
