A 14K stamp means 14-karat gold — 14 parts gold out of 24, or about 58.3% pure. It's the go-to purity for American fine jewelry because it holds up to daily wear while still carrying substantial gold value. The European equivalent stamp is 585.

What is a 14K piece worth?

14K is the most popular gold purity in the US: enough gold for real value (~$56/gram at ~$3,000/oz) and enough alloy to resist scratches.

How to verify a 14K stamp

Scan the 14K stamp with the Hallmark Reader to confirm it's solid gold and not a '14K GP/GF' plated mark. Anyone can stamp a mark on metal, so a hallmark alone isn't proof — the fastest way to check is to photograph the stamp and run it through the free Hallmark Reader, then confirm the metal itself with the Is It Real? tool.
