About Rhodium — The Rarest Precious Metal
Rhodium is the rarest and most valuable of all precious metals. Annual global production is only about 30 tonnes — roughly 1/6th of platinum production. It is a platinum group metal (PGM) primarily mined as a byproduct of platinum and nickel mining in South Africa, which produces over 80% of the world's supply.
The dominant use for rhodium is in catalytic converters for gasoline vehicles, where it specifically reduces nitrogen oxides (NOx) into nitrogen and oxygen. Unlike palladium and platinum, there is no viable substitute for rhodium in this application, which contributes to its extreme price volatility.
Rhodium is also widely used as a plating material in fine jewelry. "Rhodium-plated" white gold and sterling silver receive a thin layer (typically 0.5–1.0 microns) that provides a brilliant, reflective finish and prevents tarnishing. However, the amount of rhodium used in plating is extremely small — usually less than 0.01 troy ounces per item.
Due to its rarity and thin market, rhodium prices can be extremely volatile. The price has ranged from under $1,000/oz to over $29,000/oz in recent years. Investors should be aware that rhodium is illiquid compared to gold, silver, or platinum.
