Sample Reports

IGI screens every gemstone using state of the art technologies to determine naturally mined, laboratory grown or simulant origin. Experienced graduate gemologists conduct further assessment in controlled conditions, detailing relevant gemological characteristics according to the strictest international system. A detailed photograph will be included, and the country of origin is stated if gemological analysis conclusively reveals it.

Precious stones should only change hands when accompanied by a grading report attesting to quality. Regardless of location or marketplace, an authentic IGI Laboratory Report is the common language of trust and confidence in the gemological world.
