"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: 
<li> gem formation </li> <li> mining </li> <li> the diamond industry </li> <li> conflict diamonds </li> <li> ethical sourcing </li> <li> crystal structure (diagrams and cuts) </li> <li> optical and physical properties </li> <li> fashioning and cutting (properties and uses) </li> <li> gemstone cuts for diamonds </li> <li> buying a diamond </li> <li> buying colored gemstones </li> <li> imitation and synthetic gemstones </li> <li> gemstone enhancement </li> <li> history of gems </li> <li> famous diamonds </li> <li> caring for gemstones and jewelry </li> <li> a color key of 139 gemstones. </li> 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.

Breathtaking color photographs, especially commissioned and in a fresh new layout that's completely revised from earlier editions, capture the glistening beauty of gemstones from around the world--stones used for jewelry and magical rites as far back as 20,000 years ago. This feast for the eyes shows uncut stones and gems in their natural state, details how they are formed and mined, and also includes such exquisite jewel-adorned creations as a Spanish Renaissance pendant with Columbian emeralds, the Black Prince's ruby set in the British Imperial State Crown; a Mayan jadeite mask, and the Koh-i-Noor diamond. For a full understanding of their fascination, look beyond their visible magnificence to the gems' structure and physical attributes. Besides the most popular gemstones, you'll find fascinating descriptions of common imitations and synthetics--and advice on distinguishing the real from the fake. Note: This book is published in cooperation with the prestigious The Natural History Museum.
