Corundum

Richard W. Hughes  |  1990

Rubies and sapphires are widely considered to be among the most sought after and precious of gems. Together they account for over fifty percent of the world trade in colored gemstones. This book is the first from Richard Hughes on the subject, and the first major work to be devoted entirely to the corundum family of gemstones. It covers all aspects of rubies and sapphires, beginning with their history, chemical and physical properties. Other chapters look at treatments, synthetic corundums, methods of fashioning, famous rubies and sapphires, formation of corundum deposits and world sources, providing a valuable reference source for jewelers, gemologists, students, and the general reader.
