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-market stones like charcoite. Additionally, this all-inclusive volume includes imitations, synthetics, and combined stones. Charts and tables help you identify unknown gemstones and--when you're in the market--how to check for genuineness.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eBinding Type:\u003c\/b\u003e Hardcover\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Sterling\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 07\/02\/2013\u003cbr\u003e\u003cb\u003eISBN:\u003c\/b\u003e 9781454909538\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 319\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 1.41lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 7.81h x 5.25w x 0.96d","brand":"Walter Schumann","offers":[{"title":"Default Title","offer_id":36651608735900,"sku":"9781454909538","price":25.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0473\/0804\/6492\/products\/img_67b52310-eb38-43a5-a067-dbdb8a0369e9.jpg?v=1603877966","url":"https:\/\/pastforward.org\/products\/gemstones-of-the-world-9781454909538","provider":"Past Forward","version":"1.0","type":"link"}
