Rhodium-plated jewelry has a thin layer of rhodium applied over another metal to give it a bright, reflective finish and additional surface protection. The technique is especially common with white gold, where rhodium creates the crisp white appearance many people associate with white gold engagement rings and wedding bands. Rhodium can also be applied to sterling silver and other metals.While rhodium plating can make jewelry look brighter and help protect the underlying metal, the finish doesn’t last forever. Understanding how rhodium plating works, how long it lasts and how to care for it can help you decide whether it’s right for your jewelry.
Sandler’s Diamonds & Time can inspect, repair and professionally rhodium plate jewelry in Mt. Pleasant, SC, serving customers throughout the Charleston area.
Rhodium is a rare, silvery-white precious metal. It’s a member of the platinum group of metals, along with platinum, palladium and several others. It has a bright, highly reflective appearance and is resistant to corrosion and tarnishing. Rhodium is also harder than some other metals commonly used in fine jewelry, such as gold and silver.
Despite these properties, solid rhodium jewelry is uncommon. Rhodium can be difficult to work with, and its rarity makes it expensive. Instead, jewelers often use a very small amount of rhodium as a thin coating over another metal. This allows your jewelry to benefit from rhodium’s bright appearance and protective properties without requiring the entire piece to be made from it, which would otherwise be very costly.
Rhodium plating is the process of applying a thin layer of rhodium to the surface of another metal. You may also hear this process referred to as rhodium dipping, especially when discussing white gold rings.
The plating changes the surface of the jewelry rather than its underlying composition. For example, a 14K white gold ring remains 14K white gold after rhodium plating. The rhodium simply creates a bright outer finish over the gold alloy.
Rhodium plating can be used on rings, earrings, necklaces, bracelets and other pieces. It’s commonly used with white gold jewelry because rhodium produces a brighter and whiter appearance than most white gold alloys naturally have.
Rhodium is applied through a process called electroplating. The jeweler first thoroughly cleans the piece to remove dirt, oils and other substances from its surface. Depending on its condition, your jewelry may also be polished to remove scratches and create a smooth surface.
Your jewelry is then placed into a rhodium plating solution, where an electrical current helps deposit a thin layer of rhodium onto its surface. After plating, the piece is rinsed, dried and inspected.
Preparation is an important part of the process because plating follows the surface beneath it. Scratches, residue or other imperfections can affect the appearance of the finished piece, which is why professional cleaning and polishing may be necessary before rhodium is applied.
Rhodium can be applied to several metals used in fine jewelry, although it works better for some than others. White gold and sterling silver are the most common choices because their underlying colors are relatively close to rhodium’s silvery-white appearance.
White gold is the most common example of rhodium-plated jewelry. White gold is created by combining gold with white-colored alloy metals, but the resulting metal may still have a slightly warm, gray or yellowish appearance.
Applying rhodium creates the bright, cool-white finish many people associate with white gold. For this reason, white-gold engagement rings and wedding bands are frequently rhodium plated.
Sterling silver can also be rhodium plated. The coating gives silver a brighter, highly reflective finish while creating a barrier between the underlying silver and the surrounding environment. This can help protect the silver against tarnishing while the plating remains intact.
Because the rhodium is only a surface coating, rhodium-plated sterling silver should be cleaned more gently than untreated silver. Aggressive silver polishing can gradually remove the plating.
Yellow and rose gold can technically be rhodium plated, but it’s less common. Rhodium’s silvery-white color covers the original gold color, temporarily giving the piece a white appearance.
As the plating wears away, however, the yellow or rose gold underneath becomes visible. The contrast makes worn areas especially noticeable, so these pieces require more frequent maintenance to maintain an even white finish.

Platinum can be rhodium plated, but it generally doesn’t need to be. Platinum is naturally white, so it doesn’t require rhodium to mask a warmer underlying color.
Rhodium may occasionally be used when a particularly bright or reflective surface is desired, but many people prefer platinum’s natural appearance and allow it to develop its characteristic patina over time.
Rhodium plating can improve the appearance and surface characteristics of jewelry, but it also introduces an additional maintenance requirement. Whether it’s worthwhile depends largely on the type of jewelry and the finish you prefer.
Some of the main advantages of rhodium-plated jewelry include:
There are also some drawbacks to consider:
There’s no set amount of time that rhodium plating lasts. Its lifespan depends on the jewelry, how often you wear it, the thickness and quality of the plating and how much friction or chemical exposure the piece experiences.
Rings need replating more frequently than necklaces and earrings because they regularly come into contact with your skin, countertops, clothing, soap, water and other surfaces. A white gold engagement ring worn every day, for example, will show wear much sooner than a necklace worn only for special occasions.
Rather than following a fixed replating schedule, pay attention to the appearance of your jewelry. If white gold begins to develop warmer or yellowish areas or the finish becomes uneven, it’s likely time to have the piece inspected and replated.
The cost of rhodium plating varies depending on the piece, so there isn’t one price that applies to every piece of jewelry. Factors can include the item’s size and design, its current condition and the amount of preparation required before plating.
For example, jewelry with scratches or surface damage may need to be cleaned, polished or repaired before a new layer of rhodium is applied. More complex pieces may also require additional work. Our professional jewelers can examine your jewelry and determine what work is needed before providing an accurate price.
Good care can help preserve the finish of your rhodium-plated jewelry, although no cleaning routine can completely prevent the plating from wearing away.
For routine cleaning, use mild soap, warm water and a soft, nonabrasive cloth. Avoid harsh jewelry cleaners, abrasive polishing compounds and aggressive scrubbing, which can wear away the thin rhodium layer.
You can also help extend the life of the finish by removing your jewelry before swimming, cleaning or working with household chemicals. Try to limit direct exposure to perfume, lotions, cosmetics and similar products by applying them before putting on your jewelry.
When you’re not wearing a piece, store it separately from other jewelry to reduce unnecessary scratching and friction. Frequently worn fine jewelry should also be inspected periodically so a jeweler can identify loose stones, worn settings or plating that may need attention.
A change in your jewelry’s color doesn’t necessarily mean something is wrong with the underlying metal. If a white gold ring starts looking yellow, dull or uneven, the rhodium finish may simply be wearing away.
Sandler’s Diamonds & Time provides jewelry repair and rhodium plating in Mt. Pleasant, SC, for customers throughout the Charleston area. If your white gold or rhodium-plated jewelry has lost its bright finish, bring it to Sandler’s for an inspection and recommendations for restoring its appearance.
Yes. Rhodium plating is a thin coating over another metal and gradually wears away with use. How quickly this happens depends on the piece, how often it’s worn and the conditions it’s exposed to.
Friction, frequent wear and exposure to chemicals can accelerate wear. Rings lose their plating faster because they regularly encounter skin, water, soap, lotions, cleaning products and hard surfaces.
Look for changes in color or an uneven finish. On white gold, worn areas appear warmer or slightly yellow compared with areas where the rhodium coating remains intact. High-contact areas, such as the bottom of a ring, often show wear first.
Rhodium itself is highly resistant to tarnishing. However, once the plating becomes thin or wears away, the exposed underlying metal will react differently depending on its composition.
Rhodium itself is generally considered hypoallergenic and can create a barrier between your skin and the underlying alloy. However, because plating can eventually wear away, it doesn’t permanently prevent contact with metals beneath it.
Yes. Rhodium-plated jewelry can be resized and repaired when the underlying piece allows for it. However, procedures involving heat, soldering or polishing may disturb the rhodium finish, so your jewelry may need to be replated afterward.
Yes, rhodium plating can be professionally removed through polishing or other refinishing techniques. Because removing the coating can also affect the surface beneath it, this work is best performed by an experienced jeweler.
