What Does 585 Mean on Jewelry?

If you see 585 stamped on a ring, chain, or clasp, you're looking at 14-karat gold. It's the European millesimal way of writing 14K: the number is the parts of pure gold per 1,000, so 585 = 58.5% gold, with the rest made up of alloy metals like copper and silver for strength.

What is a 585 piece worth?

As solid 14K, a 585 piece has real melt value — about 58.5% of its weight is gold. At a ~$3,000/oz gold price, that's roughly $56 of gold per gram of 14K.

How to verify a 585 stamp

Confirm the 585 mark is genuine and the piece isn't just plated by scanning the stamp with the Hallmark Reader, then check the metal with 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.
