the mark
what 875 means.
875 is 875 parts gold per 1,000, exactly 21 karats out of 24. it sits between 22k and 18k in both gold content and color.
it's slightly harder than 22k, so it holds detail and resists scratches a little better, while still reading as rich, high-karat gold.
before you trust it
how to check a 875 stamp.
- hold a strong magnet to it. gold isn't magnetic, so a piece that pulls toward the magnet isn't solid gold. a steel spring inside a clasp can still be magnetic on a genuine piece, so test the body, not the clasp.
- check the edges, the inside of the band and the back of the clasp, where pieces wear first. if a different color shows through, silver, copper or gray, it's plated, whatever the stamp says.
- for certainty, ask a jeweler or gold buyer for an XRF scan. it reads the metal's composition in seconds without scratching the piece, unlike an acid test.
