The big book of corundum.  One of the highlights of the show wasn’t a gem or jewelry but the long-awaited compendium on Ruby and Sapphire a gemologist’s guide by Richard Hughes.  He, Wimon Manorotkul and E. Billie Hughes have produced the ultimate resource on corundum to compliment his other works on the subject.  Dick is the 2010 recipient of the Antonio C. Bonanno Award for Excellence in Gemology, a storied researcher, lecturer and principal of Lotus Gemology in Bangkok Thailand.   At about $40 US per pound, (five pounds) this is a bargain.
