Gemologist Richard Hughes, of Bangkok-based Lotus Gemology lab, has released “Ruby & Sapphire: A Gemologist’s Guide,” a companion resource to his 2014 volume “Ruby & Sapphire: A Collector’s Guide” that’s aimed specifically at working gemologists, appraisers and students. There’s a new book out that will give all the information on the two corundum varieties a gem hound could want, and more. New York-Ruby and sapphire lovers, take note.
