Start a jewelry appraisalThe quick answer
Old jewelry marks usually fall into five groups: metal marks, maker marks, designer or retailer marks, country or assay marks, and patent or inventory marks. Read the mark together with the whole object.
What to check first
- Metal marks: 10k, 14k, 18k, 22k, 375, 585, 750, 925, sterling, platinum, PT, or silver plate terms.
- Maker marks: initials, symbols, full names, workshop stamps, or signed designer marks.
- Location: inside band, clasp tab, brooch back, earring post, pendant bail, watch case, or chain tag.
- Wear: worn, double-struck, fake, partial, repaired, or added marks need caution.

- Box, receipt, certificate, old appraisal, family note, or provenance.
When to get a professional appraisal
Use professional appraisal when the mark suggests gold, platinum, sterling, designer work, Native American attribution, antique age, diamonds, estate use, insurance, donation, or sale.
