Diamonds in nature : a guide to rough diamonds

Diamonds in Nature: A Guide to Rough Diamonds illustrates the range of crystal shapes, colours, surface textures, and mineral inclusions of rough, uncut, naturally forming diamonds.

Each chapter contains photographs that show the unique physical characteristics of the diamonds, and the accompanying text describes the processes that led to their formation.

This book is an invaluable reference manual for professional geoscientists-including gemmologists and exploration geologists.
