Coloured Gemstone Report

Colored Stone Report

Premium IGI has equipped ourselves with state of the art equipments available for the use in the identification and authentication of colored gemstones. Each Premium IGI Coloured Gemstone Certificate clearly states whether the stone is natural or synthetic. The certificate identifies the variety of the gemstone, its shape, carat weight, cut, colour quality, measurements, transparency factor and major optical characteristics. If the stone has undergone any treatment, this information will be listed on the certificate as well.

Coloured Gemstone Report

IGI screens every colored stone 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 full grading 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.
