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 4Cs: the Carat weight, Color, Clarity and Cut. These are analyzed and the results are recorded in the IGl Diamond Report.

This big, full-page report, containing all report details, a diamond diagram, and unique security features, comes in slightly different sizes, depending on the IGI location where it was issued: United States: 8,5in x 11in (218mm x 278mm) and elsewhere: 210mm x 290mm (8,25in x 11,4in)

Upon request, IGI seals the stone(s) in a plastic container including a reduced copy of the original report to assure the jeweler and the consumer that the gem corresponds to the gemological report. Measurements: 76mm x 40mm (3in x 1,6in)

This folding report offers a passport style presentation and measures 87mm x 122mm (3,5in x 5,8in)

This report format with rounded corners - 86mm x 54mm (3,4in x 2,2in) - offers the option of a plasticized report, adding to the security features and standard report data as well as the high resistance to wear and tear of a common credit card.

Slightly larger than a credit card - 100mm x 70mm (3,9in x 2,8in) - this format can include the same data as the credit card sized report, in a thinner paper format, when both size and weight are important.
