This is the standard reference for over twenty years, now completely revised and updated with many new illustrations. "Gemstones of the World" is the most comprehensive and informative colour manual of the world's gemstones and includes more than 1,400 examples. Opposite each illustration the text provides an exact description of the particular stone, including details of the properties and chemical composition which makes the stone unique. Information on location of major deposits, alternative names, stones most easily identified incorrectly, and diagrams of their crystal habits are also given. The tables on gemstones' properties and constants provide a basic system of elimination for all unidentified stones. There are also eleven tables listing commercial and mineral names, refractive indices, dispersion, pleochroism, fluorescence, absorption spectra and specific gravities of gems. From the historical to the scientific, this extraordinary reference source is filled with fascinating facts about gemstones, both precious and semi-precious. It's also a worldwide scientific survey, with stunning colour photographs of each gem and its varieties.
Wonderful informative book. I can actually understand the info in it. A great buy

The boyfriend fears me now
He thinks I bought this book as a hint to him, when really I'm just a geek geologist who likes pretty rocks. This book has beautiful specimen photos as well as lots of great info, including mineralogical data and nomenclature. An excellent reference! Schumann rocks1

A Rock Hound's Treasure
The book is full of beautiful photographs, simple but scientific explanations make this book readable to even a beginner in the field of gemology or rock hunting. A must for every person who has a "passion" for gemstones.
