[FREE] [DOWNLOAD] Gemstones of the World: Newly

<b>This is truly the ultimate one-volume book every hobbyist, jeweler, jewelry maker, and rockhound will ever need!</b><br />  <br /> Following the spectacular success of the first four editions of <i>Gemstones of the World</i>, the revised fifth edition exhibits important updates and a beautiful new cover. All the gemstones ever discovered—now over 1,900—are treated in their many variations. More than 1,500 full-color photos showcase each precious and semiprecious stone in both its rough natural state and its polished and cut renditions. Each entry offers complete information on a gemstone's formation and structure, physical properties and characteristics, methods of working, cutting, and polishing. You’ll find full treatments of lesser-known gems, from andalusite to vesuvian, and a special section devoted to rocks as precious stones, including alabaster, onyx, obsidian, and fossils. Organic gem materials, such as coral, ivory, amber, and pearl, are also covered along with new-on-the-
