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
