Organic gem materials such as coral, ivory, amber, and pearl are also covered, along with more recently discovered stones like charoite. Additionally, this all-inclusive rocks and minerals book 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 authenticity.
