For over two decades, the Gemstone Industry & Laboratory Conference (GILC), organized by the ICA every year, has provided a space for industry peers to discuss worldwide gemstone issues like ethical practices, nomenclature, consumer confidence, terminology, and accurate use of laboratories for certification and grading purposes.

A Conversation Between Gem Suppliers and Professional Gemological Laboratories

Moderating the conversation at the GILC this year will be ICA secretary and AGTA vice president Bruce Bridges, Bridges Tsavorite.

Short presentations will feature AGTA president, Jeffrey Bilgore, Dr. Adolf Peretti, GRS GemResearch Swisslab, a representative from the Gübelin Gem Lab (GGL), the Swiss Gemmological Institute (SSEF), and ICA member Christopher Smith, American Gemological Laboratories (AGL), as well as ICA past president Andrew Cody representing the Australian Opal Association.

This year’s agenda concerns color nomenclature, including the validity and necessity for “Pigeon Blood,” “Royal Blue,” “Muzo Green,” as well as a look at the validity and necessity for “African Paraiba.” Cody will be giving an update as to Australian opal nomenclature.

Entrance for the 2018 GILC will be by Invitation Only. To find out about invitations, and more about the event in general, please contact the ICA New York Office, at 1-212-620-0900, or by e-mail at This email address is being protected from spambots. You need JavaScript enabled to view it..
