All the gemstones are treated in their many variations: more than 1,500 full-color photos showcase each precious and semiprecious stone in both its rough, natural, and its 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, from andalusite to vesuvian, and a special section is devoted to rocks as precious stones, including alabaster, onyx, obsidian, and fossils. Organic gem materials are also covered, such as coral, ivory, amber, and pearl. Charts and tables help collectors identify unknown gemstones and check for genuineness. | All the gemstones are treated in their many variations: more than 1,500 full-color photos showcase each precious and semiprecious stone in both its rough, natural, and its polished and cut renditions.

Welcome to The Gemology Project The Gemology Project is a non-profit gemstone and gem science wiki-style database for anyone interested in gemstones and gemology (gemmology). Every month we highlight a gemstone and a piece of gemstone identification equipment to help us all understand more about the wonderful world of colored stones and diamonds. The Project begins with a general tutorial as an Introduction to Gemology. We invite every gemologist, gemstone dealer or gem enthusiast to share their practical and theoretical gemological knowledge and help this central gemology repository grow. You can navigate through the site with the aid of our Contents page
