A jewelry item consisting of a precious metal core coated with another, more durable metal. The base is commonly sterling silver, chosen for its malleability and affordability. This is then covered with a thin layer of rhodium, a member of the platinum family known for its reflective white color and resistance to tarnish. An example would be a necklace designed to mimic the appearance of platinum or white gold at a lower cost.
The application of rhodium enhances both the aesthetic appeal and the longevity of the underlying silver. It provides a bright, lustrous finish while protecting the silver from oxidation and scratches. Historically, such plating techniques have been employed to improve the wear resistance and visual properties of various metal objects, extending their lifespan and reducing maintenance requirements.
