Marcus Origlieri will be hosting the November meeting. Nathan Renfro will present a lecture on Microworld of Gems and Minerals. Mr. Renfro is senior manager of the gem identification department at the Gemological Institute of America (GIA), in Carlsbad, California. He is also a microscopist in GIA’s Inclusion Research Department, a contributing editor of the “Microworld” column, in GIA’s professional journal, Gems & Gemology, as well as a member of the journal’s editorial review board. His primary areas of interest are photomicrography and identification of inclusions, gemstone cutting, and defect chemistry of corundum. Renfro has lectured internationally and authored or co-authored more than 100 articles on gemological topics. His photographic work has appeared in National Geographic and has been featured by Zeiss, Nikon, and Olympus. Renfro is a GIA Graduate Gemologist and earned a FGA certification from the Gemmological Association of Great Britain. A native of western North Carolina, he developed an interest in minerals during his late teens, which was sparked by his grandfather’s rock collection.
