0in 0in 0pt"> Gemstones of the World is the single, cornerstone volume that every hobbyist, jeweler, jewelry maker, and rockhound needs. And this updated edition contains a new chapter on the treatment of gemstones, expanded information on what’s New on the Market,” and 400 additional stones.More than 1,500 full-color photos showcase each precious and semiprecious stone in its rough, natural, polished, and cut renditions. Each entry offers complete information on the gemstone’s formation, structure, physical properties, and characteristics, along with the best methods of working, cutting, and polishing it. There are even full treatments of lesser-known gems; a special section on rocks as precious stones; and organic gem materials. Charts and tables (including the double fraction” figures that experts want) help collectors identify unknown gemstones and check for genuineness.
