1 jeweler, compiled from public sources. Many jewelers offer valuation services in house or through a valuer they work with, so call ahead to ask.
Scan your piece with GemstoneAI first. You get an identification, treatment and authenticity signals, and a market value estimate, so the conversation with a valuer starts from something rather than nothing. Free to try.
Fees vary by valuer and by piece, and are usually charged hourly or per item rather than as a percentage of value. Ask for the fee basis in writing before you hand anything over. A percentage-of-value fee is a reason to ask more questions.
Bring the piece, any paperwork you already have (a lab report, a receipt, an old valuation), and photographs of it in good light. Knowing roughly what the piece is before you arrive makes the conversation shorter and cheaper.
No. GemstoneAI identifies a stone from a photo and estimates market value, which is a good starting point and a way to know what questions to ask. It is not a certified valuation, and for insurance, probate or resale of a significant piece you want a credentialed professional.
