What does 375 mean on jewellery?
375 means 9K · 37.5% gold (Gold). Solid precious metal
Solid gold. Scrap value is real but modest — a little over a third of the piece weight is actual gold.
What the mark tells you
The UK and Commonwealth entry-level gold standard. Legal to call gold in the UK, but NOT in the US, where 10K is the legal minimum.
Is it worth anything?
Solid gold. Scrap value is real but modest — a little over a third of the piece weight is actual 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.
