Palladium

Palladium is a metal, the 46th element in the periodic table and belongs to the group of platinum metals.

Like platinum and white gold, it is absolutely a "newcomer" in jewellery, as it has only been used for about 100 years.

It is not as rare as platinum, but is in no way inferior to it in many other properties:

  • it is anti-allergenic.
  • It is very hard, whereby Brinell and Mohs have to be distinguished here as well.
  • It is also chemically resistant.
  • The biggest difference between the two metals is probably their density: Palladium is much lighter than platinum. Therefore palladium is a nice alternative to platinum.


Palladium is alloyed with silver and copper in purity grade of 950/-.

Palladium is used in high-quality white gold alloys as a "whitener".
