What is Rhodium Plated Jewelry: 14 Frequently Asked Questions
When it comes to jewelry, there’s more to a metal than just its color. Choosing between rhodium-plated, sterling silver, or white gold is a significant decision. While all of these metals share a silver hue, they differ in durability, shine, and cost. If you’re looking for high-quality rings, necklaces, or earrings that have a brilliant white luster, rhodium-plated jewelry might be your best option. Not only does it enhance the jewelry's appearance, but it also adds a layer of protection, especially for delicate gemstones. Rhodium could very well be the sparkle you've been looking for.
To help you determine whether rhodium-plated jewelry is the right choice for you, we have compiled answers to some of the most frequently asked questions.
Rhodium Plating Defined
What is Rhodium?
Rhodium is one of the whitest and most precious metals used in jewelry. It’s rarer than gold or platinum and is even whiter than silver. Since rhodium is typically a byproduct of platinum mining, it’s highly valuable and is part of the platinum group of metals, which includes Platinum, Rhodium, Iridium, Ruthenium, Osmium, and Palladium. Rhodium’s extreme shine, reflectivity, and strength make it desirable in the jewelry industry as well as in industries that manufacture automobiles, mirrors, and lighting.
What Does “Rhodium Plated” Mean?
Rhodium-plated jewelry is crafted from a base metal—typically gold, silver, or an alloy—and coated in a thin layer of rhodium. This plating enhances the jewelry's strength, durability, and shine. Jewelry that is rhodium-plated is more resistant to scratches, dents, and corrosion than non-plated pieces and retains its luster over time.
Rhodium Plating: Before and After
What Color is Rhodium?
Rhodium has a vibrant, silvery-white color and is highly reflective. At Woner International, we choose rhodium plating for our designs because of its brilliant quality and enhanced shine, making it a preferred choice over white gold or platinum. While the standard color of rhodium is silver, it can also be bound with inks in different hues, such as black, rose, or yellow.
Black Rhodium Plating
Black rhodium can be achieved by binding black ink to the metal during the plating process. This gives the jewelry an edgy, bold, and mysterious appearance. However, black rhodium requires more upkeep, as its color can fade and need retouching, which adds to the cost of maintenance.
Why Choose Rhodium Plating for Jewelry?
Rhodium-plated jewelry provides an extra layer of protection and produces a much brighter and whiter shine than sterling silver, white gold, or even platinum. Since rhodium is extremely strong yet brittle, jewelry cannot be made entirely from solid rhodium. However, a layer of 0.75-1.0 microns is perfect for protecting and enhancing the base metal, ensuring longevity and maintaining the brilliant appearance of the piece.
Is Rhodium Hypoallergenic?
Yes, rhodium is hypoallergenic. Since it doesn’t contain nickel, which can cause allergic reactions, it’s a safe option for individuals with sensitive skin. Rhodium plating also prevents skin irritation caused by other metals, especially those alloyed with nickel.
Is Rhodium Jewelry Safe to Wear?
Absolutely. Rhodium is non-toxic, hypoallergenic, and safe for individuals with sensitive skin, babies, and even new piercings. Its nickel-free composition means it won’t irritate the skin or cause rashes.
Does Rhodium Tarnish?
Rhodium is resistant to tarnish and corrosion. It does not rust and does not need to be alloyed with metals like copper or nickel, which typically cause jewelry to corrode or tarnish over time. A well-maintained rhodium-plated piece will keep its sheen for a long time.
Rhodium Plating vs. Other Metals
Rhodium-Plated Sterling Silver
Sterling silver is often used as the base metal for rhodium plating. Since silver is soft, rhodium plating adds durability, preventing scratches and tarnishing. Sterling silver consists of 92.5% silver and 7.5% alloy (usually copper or nickel), which can cause tarnishing. Rhodium plating, however, prevents this issue, offering the best of both worlds—sterling silver's beauty and rhodium's longevity.
Rhodium vs. Silver
While sterling silver is beautiful, it tarnishes easily and isn’t as white or reflective as rhodium. Rhodium’s reflectivity gives it a superior luster. Additionally, silver is softer and more prone to scratches, making rhodium plating an excellent solution for enhancing silver jewelry.
Rhodium-Plated vs. Solid Sterling Silver: Which is Better?
It’s not necessarily about choosing one over the other; rhodium-plated sterling silver is often the best option. Rhodium adds durability, and since the base metal and plating share a similar color, it’s less noticeable when the plating begins to wear off, allowing for longer intervals between replating sessions.
Rhodium-Plated Brass
Although brass is often used in fashion jewelry, it’s not an ideal base metal for rhodium plating, especially for fine jewelry. Brass is corrosive, and the thin rhodium plating used on brass jewelry wears down quickly, causing the jewelry to tarnish and turn green. It’s a better investment to choose higher-quality base metals, such as silver or gold.
Rhodium vs. Platinum
While both are precious metals from the same family, rhodium is rarer and has a higher price tag than platinum. However, platinum is more malleable and can be used to create solid pieces, unlike rhodium. Rhodium’s superior reflectivity makes it a popular choice for enhancing platinum jewelry.
Rhodium vs. Gold
The most noticeable difference is the color—gold is warm and yellow, while rhodium is cool and silver. Solid gold jewelry can be more expensive than rhodium-plated pieces, but rhodium offers a shinier, more reflective finish. Rhodium plating is sometimes applied to white gold to give it a whiter, brighter appearance.
Caring for Rhodium-Plated Jewelry
How Long Does Rhodium Plating Last?
On average, rhodium plating lasts around a year, though this varies based on how often the jewelry is worn. Pieces worn daily may need replating every 6 months, while occasional-wear items may last several years before needing maintenance. If you begin to see the base metal through the rhodium, it’s time to replate.
Cleaning Rhodium-Plated Jewelry
Avoid excessive cleaning, as friction can wear down the rhodium plating. Rhodium does not tarnish, so regular cleaning isn’t necessary. If you must clean it, use gentle, non-abrasive materials, and avoid harsh chemicals, soap, or water.
Rhodium Plating: Is It Worth the Investment?
Rhodium plating costs between $40-$100, depending on the complexity of the piece. While rhodium itself is more expensive than gold or platinum, the plating process is affordable and offers a high return in terms of durability, appearance, and value.
