What is Rhodium Plated Sterling Silver? + Pros & Cons

An item described as having a rhodium finish over sterling silver consists of a base metal, specifically 92.5% pure silver alloyed with other metals (typically copper), that is then coated with a thin layer of rhodium. Rhodium is a rare, silver-white, hard, corrosion-resistant, and chemically inert transition metal. The application of this coating provides a protective layer and alters the surface characteristics of the underlying silver alloy.

The practice of applying a rhodium layer enhances the tarnish resistance of the silver, as rhodium does not readily react with air or other substances that cause silver to darken over time. This plating imparts a brighter, more durable finish compared to uncoated silver. Historically, rhodium plating has been favored for its ability to increase the lifespan and aesthetic appeal of fine silver items, minimizing the need for frequent polishing.
