Gems on Canvas is a particularly interesting feature in this quarter’s G&G. Authored by Britni LeCroy, staff gemologist in GIA’s Carlsbad facility, this article is a deep dive into the historical pigments created by grinding up gem materials and then applied as the colors we see in beautiful works of art. This is a topic that has often been talked about casually, but Gems on Canvas gives us a more thorough understanding as to when and how these materials were actually utilized.
