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.

The event is held before the Tucson gem show and unites professionals across the industry chain supply, from miners, to lapidaries, gemologists, wholesalers and designers.
