Palladium Purity

Palladium is a rare and pure metal. It is not man made as many might believe. Similar to platinum, palladium is used as an alloy of 95% purity or 950. Like silver, palladium is often mixed with gold to create white gold. Because of its high level of purity, palladium is hypo-allergenic.

Does palladium stick to a magnet?

Palladium isn’t magnetic. If the piece you have is a forgery, it may contain iron. This is because iron is an inexpensive metal that’s relatively easy to mold and shape. If your piece contains any amount of iron, it will react to a magnet.
