What does 875 mean on jewelry?

What the mark tells you

Common in the Gulf states and parts of the Middle East. Rare in Western jewelry.

You may also see it written as 21k, 21kt. They all mean the same thing.

What 875 is worth by weight, today

A piece stamped 875 is 87.5% gold, so at today's spot price the metal in it is worth $109.05 per gram. A buyer will offer 70–90% of that — they carry the refining cost and take a margin — and anything below about 60% is a poor offer.

Weigh the piece without stones if you can. A typical ring is 3–6 g, a 45 cm chain 8–15 g, a bangle 15–30 g. Stones, solder and springs add weight that is not gold.

Is it worth anything?

Solid gold, very high value. Soft — bends more easily than 14K or 18K.

Marks often confused with 875

Where to find it

On a ring the mark is almost always inside the band. On a chain or bracelet look at the clasp or the tag beside it; on earrings check the post or the back. Marks are tiny and often worn — a phone camera zoomed all the way in usually reads one better than your eye does.

A stamp is evidence, not proof

Marks wear down, are struck only partially, and are occasionally forged outright. If a piece is valuable enough to matter, have the metal tested rather than relying on the stamp alone. Equally, an absent stamp does not always mean an absent metal: older and handmade jewelry is frequently unmarked.
