IGI diamond certificate

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

I.G.I. provides a detailed certification that is not as strict as G.I.A. Like the E.G.L. the I.G.I. certification also provides more information than the G.I.A. diamond report by including the important pavilion and crown angles in their diamond report.

• Table Percentage
• Crown Angle
• Pavilion Angle
• Culet Size
• Girdle Thickness

The IGl 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 analysed by several gemmologists 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 analyed and the results are recorded in the IGl Diamond Report.
