Gemstone valuation and price history software
Good pricing starts with good records: what you paid, what it cost to cut, what you asked and what similar stones actually sold for. GemColony keeps that history on each stone and can suggest a market price from photos. These are tools for your own pricing. They are not a certified appraisal, and appraisals for insurance or legal purposes should come from a qualified appraiser.
Cost and price on the stone
Purchase cost, cutting and treatment cost, asking price and sale price stay with the stone.
AI price suggestions
The AI analysis can suggest a market price, which you can import to inventory. Treat it as a starting point (Professional plan).
Compare with real sales
Review what similar stones sold for in your own records before you set a price.
Reports
Standard and advanced reports show margin by stone type, by buyer and over time.
