Note however that the GIA small dossiers reports provide more information on the diamond than the IGI small diamond report.
IGI, on the other hand, provides a small grading report and a full grading report. “At IGI, we have seen a huge increase in double-verification demand, which means before going for a major purchase, consumers like to receive confirmation that the stone matches the original report,” Van Es noted. All diamonds will be given a diamond certificate by the GIA. IGI has noted a rise in consumers sending diamonds to a second lab for checking, which can help avoid getting duped by fraudsters. The four Cs of diamonds cut, color, clarity and carat are the characteristics that determine a stone’s value. IGI is headquartered in Antwerp and has offices in New York City, Hong Kong, Mumbai, Bangkok, Tokyo, Dubai, Tel Aviv, Toronto, Los Angeles, Kolkata, New Delhi, Surat, Chennai, Thrissur, Ahmedabad, Shanghai, and Cavalese.Established in 1975, IGI is the largest independent gemological.

The International Gemological Institute (IGI) has discovered a 6.18-carat synthetic diamond that fraudsters had misrepresented as natural by falsely pairing it with a mined-diamond grading report. GCAL (Gem Certification and Assurance Lab) is currently the only alternative to the IGI in lab-grown diamond certifications, but they are few and far between. A diamond is evaluated, measured, and inspected, with the help of standard tools, similar to a jeweller’s loupe and microscope.
