What Does 950 Mean on Jewelry?

A 950 stamp means 95% pure platinum, the standard used in most fine platinum jewelry. Often written PT950 or '950 PLAT', it's a naturally white, extremely durable, and hypoallergenic metal — which, combined with its density, is why platinum rings feel heavier and cost more than gold.

What is a 950 piece worth?

Platinum is denser and rarer than gold, so a 950 piece is heavy and valuable — often worth more than a comparable gold piece.

How to verify a 950 stamp

Confirm 950 platinum (vs white gold or plating) by scanning the mark with the Hallmark Reader and using the Is It Real? tool. Anyone can stamp a mark on metal, so a hallmark alone isn't proof — the fastest way to check is to photograph the stamp and run it through the free Hallmark Reader, then confirm the metal itself with the Is It Real? tool.
