AI Cataloging for Jewelry
Jewelry is the highest-liability category in estate auctions. A single misidentified stone or overstated karat claim can expose you to legal action. Gavelist uses identify-first protocol — describing what is visually observable while flagging items that need professional testing. You get sale-ready descriptions that protect you legally while still attracting informed bidders.

Why Jewelry Cataloging Is Challenging
- Distinguishing genuine gemstones from synthetics, simulants, or glass requires testing equipment photos cannot replace
- Hallmarks and karat stamps are often worn, requiring magnified photography to read
- Costume jewelry from Trifari, Miriam Haskell, or Eisenberg can exceed the value of unmarked gold pieces
- Estate lots often mix fine and costume pieces — each needs different descriptive treatment
- Weight and stone measurements cannot be determined from photos alone
What Gavelist Identifies from Photos
- Metal color and likely composition — yellow gold tone, white gold/platinum tone, sterling indicators
- Hallmark and maker mark identification — 14K, 925, maker stamps from major houses
- Setting styles — prong, bezel, channel, pave, tension — with era indicators
- Stone identification with appropriate hedging — 'appears to be' for untested stones
- Designer and brand signatures — Tiffany, David Yurman, Pandora, Georg Jensen
- Period classification — Art Nouveau, Art Deco, Retro, Mid-Century

Photography Tips for Better AI Results
- 1Use macro mode and photograph hallmarks with a loupe or magnifying glass for readability
- 2Shoot against a plain dark background — black velvet eliminates distracting reflections
- 3Include a ruler or coin for scale, especially for rings and pendants
- 4Photograph clasps and closures — they often carry maker marks and indicate era
