Appraisal Associations

Useful contact information if you’re looking for a professional to value your gem or jewelry item.

  Appraiser at work

GIA does not provide an appraised value for gemstones or jewelry. This service should be performed by an independent appraiser. An appraisal should contain a quality analysis, description, and valuation of the gemstone or jewelry item.

While GIA does not recommend individual appraisers, there are several national appraisal associations and networks that will be able to help you locate an appraiser in your area. Many of these associations require their appraisers to have a GIA Graduate Gemologist diploma (GG), as well as additional appraisal training. To locate an appraiser, either contact the headquarters of each association (listed below) or consult your local phone listings.
