About this book

Language: French

Garnet, emerald, kunzite, amber, agate, opal, pearls, rubies ... and hundreds of other precious stones, fine and ornamental, are described and illustrated. The richly documented introduction presents a comprehensive account of gemology: properties, deposits and extraction, treatment, mineralogical classification, etc. The descriptions of gems address both optical properties (colors, lights, fluorescence) and the mechanical properties (density, hardness, cleavage) and are accompanied by photographs. Bibliography, comparison tables and an index make this book a reference work.
