What is Rhodium Plating?

Rhodium Plating over Sterling Silver will give silver the expensive, nearly identical to the "platinum" look. As many of you know, platinum is a more expensive form of metal. Rhodium plating is also very effective in preventing the effects of oxidation, or tarnishing, and it does not need to be cleaned.

To get really technical, this is how rhodium plating is done - A barrier layer of nickel is usually deposited on silver first, though in this case it is not to prevent migration of silver through rhodium, but to prevent contamination of the rhodium bath with silver and copper, which slightly dissolve in the sulfuric acid, usually present in the bath composition.
