JCK editor-in-chief Victoria Gomelsky and news director Rob Bates interview our first-ever father-daughter guest duo, Richard “Dick” Hughes and Billie Hughes, co-founders of Lotus Gemology, a full-service colored gemstone testing lab based in Bangkok. The pair give listeners an insider’s guide to the complex world of colored stones. Why is describing faceted color gemstones “pure hell”? (“It’s like trying to describe the wind,” in Dick’s words.) How do experts really detect treated stones? Bonus: Find out how you can learn more from these experts in Tucson.
