Appraisal Services

Whether you need a gem appraisal, evaluation, photograph or analysis, GemLab's expert gemologists will provide accurate and quality reports you can count on.

Insurance Appraisal


Insurance appraisals reflect the retail value of what it would cost to replace the piece should there ever be a claim. Generally valid for 3-5 Years, at which point the value will need to be updated to reflect current market value.

Wholesale Appraisal

Wholesale appraisals reflect the relative value in a wholesale market such as the Diamond District or other similar wholesale jewelry districts. These values are generally valid for the current conditions in the market, which will fluctuate often throughout the year, closely based on diamond, colored stones, metals, and manufacturing costs.

Estate or Fair Market Appraisal

Estate or Fair Market appraisals reflect the value of what the piece(s) would sell for should the owner have to liquidate their items at current market conditions. Generally valid only for the current conditions in the market, which will fluctuate often throughout the year.

Appraisals are available on the following:

  • Jewelry (Rings, Necklaces, Pendants, Earrings, Bracelets…etc.)
  • Watches (Rolex, Patek Philippe, Breitling, Piaget, Omega…etc.)
  • Pearls (South Sea, Akoya, Freshwater…etc.)
