Lapidary artist and gemstone carver Glenn Lehrer, G.G., a graduate of the Gemological Institute of America (GIA), returned to the Institute recently to present a lecture on “Shaping Splendid Gems.” Lehrer’s talk was the second in the GIA Museum Gallery’s lecture series titled “What Makes a Gem Special? Understanding the Key Factors in Determining Beauty, Rarity, and Durability.” More than 100 attendees were on hand for the talk, in which Lehrer discussed his “thinking out of the box” approach to gem carving.
