Diamond expert witnesses typically have backgrounds and extensive experience in jewelry appraisal, gemology, jewelry design, and may be certified gemologist appraisers. Experts in diamonds 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 diamond industry issues including trade dress, trademark, trade secret, branding, insurance, and jewelry appraisal matters. Litigation support by a diamond expert witness could include research, jewelry valuation, expert report preparation, expert opinion, depositions, and testimony in court. In a high-profile dispute, or litigation involving a significant financial stake, a law firm may require a diamond specialist with prior expert testimony experience. Counsel may also seek a gemologist or jewelry industry expert for pre-litigation consultation work.
