The AGA Conference was held in Tucson, AZ on February 1, 2017. This full day meeting is a popular conference and attended by gemologists from around the world. The annual conference is followed by a dinner gala and the Antonio C. Bonanno Award for Excellence in Gemology. Christopher Smith was the first speaker. He introduced a new approach to color grading in gemology. The presentation gave a detailed explanation of how color works and how we perceive color exhibited by cut gemstones. It introduced a new color referencing system called ColorCodex. The design allows for faceted transparent stones to be compared to the reflective colors presented on the ColorCodex cards. Elise Skalwold’s presentation was titled, “From Gemology to Mineral Physics and Back Again.” Elise is an independent researcher and the Consulting Gemological Curator at Cornell University. The presentation covered her journey as a researcher to determine the mysterious blue inclusion in a diamond macle. She and her colleagues have used most advanced mineralogical testing techniques not only to identify the inclusion as an olivine but also to explain the formation conditions of the diamond crystal. This study has been published extensively. Her talk was a great reminder of importance of funding...
