"Lavishly illustrated, Gems of the World is intended for anyone who has ever been fascinated by crystals, jewelry, and gems, from general readers to seasoned professionals. It is a fine addition to general collections." --Booklist, on the previous edition
Gems of the World is a practical and comprehensive guide to the identification and properties of precious and semiprecious gems, novelty stones, agates and crystals. This edition has been revised and thoroughly updated. Changes and new features include updated maps of recently established diamond bourses and geographical country changes, plus new gem varieties and localities where they are found, new techniques for producing synthetic gemstones and simulants, and much more.
There is comprehensive information on gems:
The text describes the world's diamond cutting and trading centers, the "diamond pipeline" that flows from mine to retail, and information on the gemstone industry, ethical mining, conflict diamonds and the emergence of new diamond centers.
The description directory of gemstones is organized by their chemical composition. The 139 profiles describe each gem's geology, chemistry, properties (such as color, refractive index, and luster), cultural use in history and its value in jewelry. Photographs show the gem as a raw crystal, in common cuts, polished for use, and in some cases, also in a piece of jewelry.
Gems of the World is an ideal reference for gemologists, collectors and general readers.
