Gemology, a branch of mineralogy, is the science that deals with gemstone materials (natural or artificial). A gemology expert witness typically has a background and extensive experience in jewelry appraisal, gem identification, jewelry design, and/or is a certified gemologist appraiser. Experts in gemology may have an affiliation with an industry organization such as the Jewelers of America, the American Society of Appraisers (ASA), the American Gem Society (AGS), and/or the Accredited Gemologists Association (AGA).

Cahn Litigation Services has placed expert witnesses in cases pertaining to a variety of gemology industry issues including copyright, trade dress, trademark, trade secret, branding, insurance, and jewelry appraisal matters. Litigation support by a gemology expert witness could include research, jewelry valuation, an expert report, expert opinion, depositions, and/or courtroom testimony. In a high-profile dispute, or litigation involving a significant financial stake, a law firm may require a gemology specialist with prior expert witness testimony experience. Counsel may also seek a master gemologist or jewelry industry expert for pre-litigation consulting work.
