All About IGI

Established in 1975 in Antwerp, the IGI today is the oldest institute of its kind with offices in New York, Bangkok, Mumbai and Tokyo. Today, the IGI issues over 400,000 reports annually, attaining the distinction of being a preeminent authority for jewelry analyses.

The IGI standard of excellence has earned the Institute an international reputation for integrity, accuracy and reliability. Combining a wealth of research and development activities with the expertise of a master staff, the IGI is thoroughly committed to the time-honored tradition of quality analysis while maintaining a look ahead to technological advances of the future.

A decade ago, gemological reports were primarily used only by diamond dealers. Today’s diamond and jewelry consumers are more demanding and quality conscientious about their purchases. A jewelry buyer wants an explanation why two similar diamond rings are priced $1000 apart and will not be satisfied with the explanation, "one is a better diamond."  The buyer demands to know and is entitled to have a fair assessment (product information) of what they are considering to purchase. Today’s jewelry consumers are aware and educated when it comes to purchasing a diamond. They are more familiar with the 4Cs than their parents and having vital information about a diamond is an integral part of the purchase or sale of an article of jewelry or gemstone.

This quest for information has led to an increased demand for independent and reliable grading reports from credible organizations that have stood the test of time, such as the International Gemological Institute (IGI).

Today, on and off-line jewelers, retail establishments, insurance companies, certified public accounting firms, international law firms and the public rely on IGI reports.
