A round table featuring seven international experts and moderated by Travis Lejman, gemologist and conference co-chair, will discuss “Sapphire Origins” and “LGD Versus Natural Diamonds.”
In addition, some presentations will further explore portable instruments for identifying gems and synthetic diamonds, as well as artificial intelligence (AI).
