This is a primer in crystal therapy. It has been written by a dealer in crystals who could not find an A-Z book to answer the basic questions repeatedly asked by his new customers. He wanted an applications book which had a strong visual content, so that his customers would be able to identify both the crystals and their purpose. From agate to zircon, in colour, we look at the most popular healing crystals sold by this leading expert. The accompanying text presents their physical attributes, origins and therapeutic benefits. There is also general guidance in terms of the kind of people and/or aspirations which each would best suit.
