What does 585 mean on jewellery?
585 means 14K · 58.5% gold (Gold). Solid precious metal
Solid gold, and the sweet spot of durability and value. Just over half the weight is pure gold.
What the mark tells you
The single most common gold standard in the US — the default for engagement rings and fine jewellery. A stamp of 583 rather than 585 usually indicates older Soviet or Eastern European origin.
Is it worth anything?
Solid gold, and the sweet spot of durability and value. Just over half the weight is pure gold.
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 jewellery is frequently unmarked.
Found something real? Value it
If the piece is solid metal or holds a stone, see what it is actually worth — both at retail and what you would genuinely be offered for it.
