IGI’s Cultured Pearl Grading Report Turns 15

The International Gemological Institute is celebrating the anniversary of its Cultured Pearl Grading Report. It was launched 15 years ago when the Institute saw a need for an integrated, comprehensive system for evaluating pertinent factors in pearl quality.

The report allows an individual to compare different strands of pearls from one supplier to the next. This report was considered a pioneering effort 15 years ago and today is all the more relevant due to the increase in consumer demand for cultured pearls, IGI said in a statement. 

The report provides a component breakdown of the pearls’ unique characteristics consisting of: identification of pearl variety, size, shape, weight, body color, and overtone, luster, surface quality, nacre thickness, matching, treatment (if applicable), and growth environment. The authenticity, content, and weight of any precious metals are also stated as well as color photographs. It is used by retailers as a sales tool and a reference guide.

“We are proud to offer the most comprehensive, reliable, and consistent method of relating the beauty of a cultured pearl to its value,” said IGI President and chief executive officer Jerry Ehrenwald, GG, ASA.

IGI is the world’s largest independent laboratory for testing and valuating gemstones and fine jewelry. It has locations in New York City, Los Angeles, Toronto, Antwerp, Bangkok, Mumbai (Bombay), Tokyo, Dubai, and Hong Kong.
