Rhodium is a silver-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.
It's like chrome, but much whiter, and the most reflective of all metals. Rhodium plating makes diamonds look bigger and better because it's so bright that it glints like the diamonds. From a couple of feet away and under most lighting conditions it's hard to see where the stones end and the metal begins. Nothing sets off diamonds like rhodium plating does.
