Gemstones: Properties, Identification And Use
Arthur Thomas
Gemstones is the essential resource for lapidarists, serious gem collectors and amateur enthusiasts alike. As well as the naturally occurring minerals that have long been prized as gemstones - for example, diamonds, emeralds and rubies - the book covers organic gems, such as pearls, amber and coral, and synthetic gems and simulants, also known as imitations. PART 1: THE WORLD OF GEMSTONES examines the appeal of gemstones, the basic rock types, principles of crystal formation and physical properties. PART 2: A GEMSTONE GUIDE makes up the main encyclopedic section of the book and provides information on the origins, properties and qualities of over 200 stones, as well as major world sources. PART 3: THE ART OF THE GEM explores the history and popularity of collecting, the cutting and finishing processes, and the ways in which stones can be enhanced or 'improved'
