Established in 1975, the International Gemological Institute (IGI) is an organization that gives certifications to diamonds, colored gemstones, and jewelry. It is the biggest independent gemological laboratory globally. IGI’s headquarters is located in Antwerp, Belgium, and has offices in 18 locations worldwide at Ahmedabad, Bangkok, Cavalese, Chennai, Dubai, Hong Kong, Hyderabad, Kolkata, Los Angeles, Mumbai, New Delhi, New York City, Shanghai, Surat, Tel Aviv, Thrissur, Tokyo, and Toronto.
The IGI offers a variety of services through its laboratories worldwide. It also certifies the most extensive variety of jewelry, gemstones, and diamonds.
IGI is known for its extensive and accurate diamond grading assessment of a diamond’s clarity, color, carat weight, and cut based on strict international standards. It uses the latest technology in determining whether the diamond is laboratory grown, naturally mined, or of simulant origin. IGI’s expert graduate gemologists further assess the diamonds in controlled settings so that they can give a more accurate and detailed diamond report.
