YA-- This fascinating reference source will be eagerly sought by rock hounds as it pulls together into one book data usually found in a variety of references. It is a perfect balance between an encyclopedia and a rock-identification handbook. Alphabetically arranged, it allows readers to look up groups of or individual minerals and their physical properties. Also included are some history and folklore surrounding the gems. Descriptions move from chemical analysis through geologic formation and on to the use of the stones, stressing the overall role of nature itself in rock formation. The excellent photos and graphics will facilitate identification and provide information on classification, hardness, gravity, etc. The index is a vital tool as no cross references are provided in the basic text (i. e., information on rubies is under corundum). --Claudia Moore, W.

Top customer reviews
resource was given as Christmas gift and she seems to
very much appreciate it. Great, intuitive rock and mineral
grading criteria, and great explanations of gem origins and
geographies. Thanks again to the seller and thanks
again to Amazon for enabling its online sale & redistribution.
Life is wonderful!
