What is rhodium and why do jewelers use it?

Rhodium plating, also known as rhodium dip or rhodium flashing, is used to increase the durability, luster and light reflection of a piece of jewelry. Because it is a hard metal, a rhodium plated piece of jewelry will be more scratch resistant. Rhodium plating is mainly used on silver-hued metals, such as white gold, palladium or silver.

What Is Rhodium?

Wollaston called the new metal rhodium, rooted in the Greek word for rose, "rhodon," because of the reddish salts that were dissolved in the aqua regia ( aqua regia is a yellow-orange fuming liquid, so named by alchemists because it can dissolve the noble metals gold and platinum).

Generally, Rhodium Is Not Harmful (Unless You're a Jeweler)

People have been mining rhodium as a by-product of platinum since the 1930s after large sediments of platinum ore were found in the Transvaal in South Africa. Since that time, there's never been concrete evidence of harm to humans, especially since it's highly unlikely for a human to come into direct contact with a substantial amount of rhodium.

What is rhodium used for?

The main use for rhodium is in catalytic converters designed to clean vehicle emissions. Rhodium — often together with palladium and/or platinum — accomplishes this by reducing nitrogen oxide in exhaust gas. Without rhodium catalysts, the air in our cities would be much worse due to vehicle exhausts.

What would happen if there was no rhodium catalyst?

While the use of rhodium mainly is not that significant, if this theory is true, then rhodium is important in the development of fuel and energy management. It may help to convert water and carbon dioxide into high power of fuel. If this is the case, another source of fuel is highly possible.

What is rhodium?

First things first, rhodium is a rare and precious element that can be 10 to 25 times more expensive than gold. Rhodium is a member of the platinum group of metals and is silver-hued, highly reflective and does not tarnish or corrode. It is harder than gold and is highly durable.

Why is rhodium plated?

Because it is a hard metal, a rhodium plated piece of jewelry will be more scratch resistant.

How thick should the rhodium plating be?

The ideal thickness for rhodium plating is .75 to 1.0 microns. Although this may sound extremely thin, it is considered thick enough for rings and other jewelry items that are exposed to rough wear. For jewelry items such as earrings and pendants that are more sheltered or for jewelry that is not worn frequently, a thickness of .10 to .50 is acceptable.

Is rhodium plated jewelry safe to wear?

Yes, it is. Because rhodium plating is hypoallergenic, you won’t get skin reactions by wearing rhodium plated jewelry. This is because rhodium does not contain any allergens such as nickel. In fact if you have a piece of jewelry that is causing you skin reactions, rhodium plating the piece can eliminate this problem.

Many shoppers believe that rhodium plating is permanent. While it is permanent, like any other metal used in jewelry, it tends to suffer wear and tear with exposure.

Will rhodium plating affect gemstones?

This depends on the gemstone. Some softer gemstones such as peridot, pearls, opals, topaz, turquoise, coral and treated or heavily included rubies and emeralds can be damaged during the process. These gemstones, and many others, are not able to cope with the sulfuric acids and heat in the electroplating solutions and their surfaces can be damaged, becoming spotty and studded.
