Rocks, Minerals & Gemstones by Walter Schumann copyright 1993 (Original German edition copyright 1985)
a Great book for identifying a rock using its geological properties. Aproximately 600 rocks, minerals and gemstones are identified by a photograph and their chemical composition, hardness, specific gravity, cleavage, color, streak, luster, transparency, crystal system, magnetism, fracture, luminescence and others. Only applicable properties listed for each specimen. Does not list the refractive index or spectrum. The book describes some of the simpler identification tests such as streak, hardness and specific gravity, but not any of the instruments used for gemstones(These are described in Schumann's other books, Minerals of the World and gemstones of the World).
A great book that goes beyond the information of the field guides.
