Located in New York City, Los Angeles, Toronto, Antwerp, Hong Kong, Mumbai, the Seepz Zone, Kolkata, New Delhi, Surat, Dubai, Bangkok, Tokyo and Tel Aviv, the International Gemological Institute (IGI) is the largest independent laboratory for grading and evaluating diamonds and fine jewelry, and is renowned for its quality services, extensive experience and expertise.

IGI, the oldest institute of its kind in Antwerp, was founded in 1975 and along with its sister laboratories, is one of the leading gemological institutions worldwide. IGI is also the only international certification lab wholly owned and controlled by one central governing body, which ensures consistency in IGI reports across the globe. In adhering to the one internationally accepted system for diamond grading, IGI offers its clients peace of mind.

For over 30 years, IGI has provided the fine jewelry community and consumers with a broad range of services including: independent diamond grading reports, colored stone reports, identification and appraisal reports, diamond authentication and attestation of origin, laser inscription services, and diamond and colored stone courses offered through IGI's School of Gemology.

Today, IGI issues more than one million reports per year, which is notable considering that 10 years ago only diamond dealers were using gemological reports. Consumers are now more demanding and quality conscious about the products they buy and as such, the majority of quality gem and jewelry items are sold with gemological reports.

A jewelry buyer seeking an explanation of why two similar diamond rings are priced $1,000 apart is not satisfied with being told simply that one is a 'better' diamond. He or she wants to know why it's better and they are also more familiar with the 4Cs than their parents were. Today, the consuming public is entitled to accurate and reliable product information. Contemporary jewelers consider supplying such information an integral part of any sale and modern retail training programs stress the importance of providing independent gemological reports for gems and jewelry in addition to educating the consumer.

All this has led to an increase in demand for reliable grading and/or appraisal reports from IGI. Thousands of jewelers, retail stores, insurance companies, Internet sales organizations, catalogue companies (mail order), accounting and securities firms and consumers alike rely on IGI reports. IGI draws upon its expert staff of over 450 including graduate gemologists, accredited appraisers and professional office personnel, all dedicated to a standard of excellence second to none. With an ever-increasing client base, IGI's reputation as an industry leader is unparalleled.

Besides exceptional stones, a gem has no name, no history. It's a gem! The final user doesn't know where the stone was found, who extracted it, who polished it or the name of the gem dealer. The only document that travels around the world with the gem is the gemological report. The IGI report is "The Passport for your gems and jewelry!"
