IGI Diamond Grading

IGI Grading Process

IGI screens every diamond 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.

The presence of any permanent treatments will be noted in the comments section. IGI will not issue reports for diamonds with non-permanent treatments.

Gemstones 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.
