A global authority in ethical gem science and appraisal standards, and the sister organization of GIA.
The Jewelry Appraiser Inc was founded on one principle established in 1989: accuracy must be guided by truth, not profit. Led by Deborah Villepigue, the world's first professional recognized as both a Gemologist and a Geologist. The firm delivers appraisals grounded in science, clarity, and complete independence. She is the world’s first and only professional recognized as both a Gemologist and a Geologist, and is also among a select few Master Gemologist Appraisers worldwide. Her appraisals are performed in person and explained clearly, so clients understand exactly what they own, why it matters, and how to protect it.
For more than 30 years, Deborah Villepigue has been chosen by private clients, celebrities, attorneys, and courts because her work is precise, independent, and defensible. In an industry where conflicts of interest are common, she operates differently. She works solely for the client. This independence allows her to stand firmly for truth, protection, and accountability. Clients return not because they are persuaded, but because they are protected.
A gemologist identifies what a stone is, but a geologist understands where it comes from, how it formed, and why it behaves the way it does. This dual expertise makes it possible to uncover subtle treatments, synthetics, and misrepresented origins that others may overlook.
When gemology meets geology, every appraisal is grounded in science rather than opinion—delivering clarity, confidence, and results you can trust.

Jewelry appraisals should provide clarity, protection, and confidence, not confusion.
Each appraisal is performed in person, with careful examination and clear explanation, so clients understand
exactly what they own and why it matters. Every report is prepared to stand up to insurance review, estate
planning, and legal scrutiny.
