内容説明
This book attempts to convey a sense of the Eastern appreciation of the ruby and the sapphire, whilst at the same time providing details of the more technical aspects of these gems, this information having come largely from the West. It aims to compensate for the lack of information currently available on the corundum gems. Corundum is chiefly an Asian gem in origin, and the author sees this fact as pertinent to the relative scarcity of published material about it. The East remains an alien region with a foreign culture, and the author considers these factors to be barriers to the free flow of information. He has lived in the East for many years, and has thus gained an insight into those gems which are Eastern in origin.
