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.","brand":"Sterling","offers":[{"title":"Default Title","offer_id":47043626926320,"sku":"9781454909538","price":24.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781454909538_p0.jpg?v=1769907325","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781454909538","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
