 Established in Antwerp, New York, Hong Kong, Mumbai, Bangkok, Tokyo, Dubai, Toronto, Los Angeles, Tel Aviv and Cavalese, IGI is the world's largest independent gem certification and appraisal institute and is renowned for its quality services, extensive experience and know-how.
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. Presently, a staff of just three has grown to over 450 professionals dedicated to a standard of excellence second to none. Today IGI issues more than 1 Million reports a year. Ten years ago, only the diamond dealer was using gemological reports. Today, consumers have become more demanding and quality conscious about the products they buy. 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 will want to know why it's better. Consequently, today's jewelry consumers are more familiar with the 4C's than their parents were. Jewelers now 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 or appraisal reports from credible organizations such as the International Gemological Institute (IGI). Thousands of jewelers, retail stores, insurance companies, internet sales organizations, catalogue companies (mail order), accounting and securities firms and consumers rely on IGI reports. Today the majority of good quality gem and jewelry items are sold with gemological reports. 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 dealer. The only document that travels around the world with the gem is the Gemological Report. It is The Passport for your Gems and Jewelry.
