The International Gemological Institute is the oldest institute of its kind in Antwerp. Set up in 1975 with labs in New York, Bangkok, Mumbai and Tokyo

The IGI Diamond Report is essentially a statement attesting to the authenticity of a diamond and providing a reliable and accurate statement of its identity and grade based on an internationally recognized system.

Each diamond is scientifically analyzed by several gemologists who use their experience in combination with state-of-the-art equipment to produce an accurate description of the characteristics of the diamond and the quality of its cut. With its detailed information presented in understandable language, the different qualities of a diamond can be truly appreciated.

The grade or quality of a diamond is based on four characteristics commonly referred to as the 4C’s: the Carat weight, Color, Clarity and Cut. These are analyzed and the results are recorded in the IGI Diamond Report.
