See what the market actually paid
GemmoPrice is not a price oracle — it is a professional intelligence platform built on 14 years of real auction evidence. The data does not tell you what a stone is worth. It shows you what the market paid, under what conditions, at what moment in time. In the hands of a trained professional, that is one of the most powerful tools in the trade.
Real auction data
Every record comes from a specialized jewellery sale at one of 8 leading international auction houses — not estimates, not asking prices. What the market actually paid.
Built for professionals
Gem dealers, gemmologists, appraisers, collectors, and auction specialists across 6 continents use GemmoPrice as their primary market intelligence reference.
Continuously updated
The database grows with every major jewellery auction worldwide. Each new sale adds records, refines the picture, and keeps your intelligence current.
