What Does 750 Mean on Gold?
Stamps describe metal content; they are not a buy/sell quote. When in doubt, test with a jeweler or assay service.
75% pure gold
If you’re selling, use the stamp to pick the right karat rate—then compare buyer offers as a percentage of melt, not headline spot.
Common confusion points
- Stamps can be partial or mirrored; a worn punch can turn a 585 into something that looks like 588 or 535.
- Some pieces combine parts (e.g., clasp vs chain) with different karats—test more than one spot if value is high.
Similar / easily-confused stamps
This stamp corresponds to 18K — about 75.0% gold content by weight.
Common in: Europe, USA, International fine jewelry. Typical items: Fine jewelry, Luxury watches, Designer pieces.
This fineness shows up often in pieces sold for or imported from Europe, USA, International fine jewelry—always match the stamp to what you actually weigh.
Illustrative: at the USD spot used on this site, 10 g of 18K gold has a rough melt around $1,087.40 (not an offer).
Verification tips
- XRF is the quickest non-destructive test; acid tests are common but depend on operator skill.
- If the piece is plated, you may see marks like GP, GF, HGE—those are not solid-gold fineness stamps.
- Look in high-wear areas (inside rings, near clasps). Worn stamps can be incomplete or misread.
Where you'll see the 750 stamp
Check inside ring shanks, near necklace and bracelet clasps, on earring posts or backs, and on small tags. Stamps can be tiny—use bright light or a loupe if the punch is worn.

How to verify a stamp
Stamps can wear down or be wrong. A jeweler can do an acid scratch test or XRF; a magnet won't stick to solid gold, but it isn't proof of purity on its own. For high-value pieces, use a buyer you trust or an independent assay.
