Question Title What is Rhodium?
Rhodium is a silvery-white hard metal often found in platinum ores. It is the most expensive precious metal.  In its natural solid state Rhodium is far too hard to work, but it is used as an alloy in the smelting of platinum and palladium.

In the 1930's some silverware makers began to use rhodium electro-plating to produce sterling flatware that would not require frequent polishing. The use of rhodium plating spread to white gold and sterling silver jewelry as a means of creating a highly durable, tarnish resistant surface.

The use of rhodium plating on base metal, "pot metal" and stainless steel jewelry findings and settings did not come into wide use until after World War II.  Advances in technology eventually allowed even thinner layers of rhodium to be bonded with the surface of metals.

While no vintage costume jewelry is "made of rhodium" or "set in rhodium", costume jewelry of good quality was often rhodium plated.
