Ruby and Sapphire: A Gemologist's Guide


English Language: English

Authors: Richard W. Hughes, Wimon Manorotkul, E. Billie Hughes


Designed as a companion volume to Ruby & Sapphire: A Collector's Guide, this volume is aimed specifically at working gemologists, appraisers and students. Based on Richard W. Hughes' 1997 classic, Ruby & Sapphire, this edition is fully updated. The product of nearly 40 years of firsthand experience and research, it covers every aspect of the subject from A–Z. History, sources, prices, quality analysis, synthetics and treatments, everything is here. Ruby & Sapphire—A Gemologist’s Guide represents the definitive reference on the subject. With over 1000 photos, maps and illustrations and 3500 references, it is nothing less than a tour-de-force of gemological scholarship.
