What does that stamp mean?
Nearly every piece of real jewellery carries a mark — usually inside the band, on a clasp, or on the back. Type it in and find out what the metal is, how pure it is, and whether the piece is worth anything by weight.
The mark on your piece
Marks are often tiny and worn. A phone camera zoomed all the way in usually reads them better than your eye does.
The three stamps that disappoint people most
EPNS · nickel silver · German silver · alpaca
None of these contain any silver at all. The word describes the colour, not the metal. This is the single most common source of disappointment in inherited jewellery.
GP · GEP · HGE — plated
A base metal core with a microscopically thin gold layer. "Heavy gold electroplate" is marketing language, not a standard. Refiners will not buy it.
GF — gold filled
Genuinely different from plating: a bonded gold layer roughly 100 times thicker. A stamp like "1/20 12K GF" means one twentieth of the total weight is 12K gold. Some refiners buy it in bulk.
Found something real?
If the piece is solid gold or holds a diamond, find out what it is actually worth — both retail and resale.
