EGL USA is the only laboratory in North America that grades rough diamonds.  Its Mineralogical and Rough Diamond Department is comprised of experts in the grading and classification of rough diamonds. EGL USA Press will publish The Morphology of Diamond Indicator Minerals by Valentin Afanasiev, a leading authority on the subject, later this year..

EGL USA gemologists have lectured on rough diamonds at the New York Diamond Dealers Club and offer seminars to the international trade on request.
