Platinum, silvery white, is extremely malleable and is not corroded by acid and alkali except aqua regia.

Palladium is a platinum group element. It is silvery white, and the symbol is Pd. It is lighter than platinum and slightly harder than platinum. Under normal circumstances, it is not easy to oxidize and lose luster. If left in the air for a long time, it will turn gray. When making palladium jewelry, rhodium plating is generally used. Palladium is relatively light and has a weak sense of value, so it is rarely used to make jewelry alone in the world. The imprint of palladium jewelry is Pd.

At present, some merchants in the market use the similar appearance of platinum and palladium to deceive consumers by charging "platinum" with "palladium".
