Part of the Platinum group of metals, palladium is hypoallergenic, pure white metal that never changes color. Palladium is often used as an alloy in platinum, but stands on its own as a less expensive and more lightweight alternative to platinum. The hallmark stamp for palladium is "Pall 950", meaning that the metal is 95% pure palladium, and 5% alloy metal.
