Available in several languages, it includes an overview of gemology, demonstrations, and other information, as well as databases of gemstones, minerals, and created and treated gemstones, each sorted alphabetically, with photographs, chemical compositions, formations, and unusual properties of each, including whether it is a birthstone, and information on its value and possible usage. Gemstone creation methods are also reviewed.
