What is Rhodium Plating. Many contemporary jewellery items especially those made of white gold and sterling silver, are electroplated in rhodium to enhance shine and durability. Rhodium is a precious metal, a member of the platinum family. Rhodium electroplating is used to provide a surface that will resist scratches and tarnish, and give a white, reflective appearance for longer.
