What Is The International Gemological Institute?

INTERNATIONAL GEMOLOGICAL INSTITUTE (IGI)

IGI is an independent grading and appraisal organization with centers in New York City and Los Angeles, as well as in Antwerp, Bangkok, Mumbai, Tokyo, Dubai and Toronto.


Several gemologists carefully analyze each diamond and produce an accurate description of its characteristics, such as color, clarity, carat weight and the quality of its cut. The information is stored in IGI's computer database so you may request an update of your report if the need arises. IGI also offers colored gemstone certificates, educational courses and laser inscription services.
