About Platinum Jewelry

Platinum jewelry is rarely 100% pure platinum. Usually, the platinum is mixed with similar metals or non-precious base metals. Generally, the higher the percentage of pure platinum, the higher the value of the jewelry.

Metals used in platinum jewelry usually fall into one of three categories:

  • pure platinum
  • other platinum group metals (palladium, ruthenium, rhodium, iridium, osmium)
  • base metals (copper or cobalt, for example)

If you want to buy platinum jewelry, find out what percentage is pure platinum, and if the item is:

  • hypoallergenic
  • durable
  • lustrous
  • dense
  • scratch and tarnish resistant
  • able to be resized or repaired
  • going to retain the precious metal over time
