Chase and Pawlik do an amazing job in writing this excellent book on gemstones as they pertain to alternative and/or complimentary medicine!
This book is broken down into three major parts: Part 1 deals with Exploring the World of Gemstones, Part 2 goes in depth with each of the particular properties of specific stones, and Part 3 deals specifically with application and healing. There is also an extensive list of illustrations that are quite good!
For an even more complete library, I recommend getting this book in addition to Chase and Pawlik's other masterpiece, "Healing with Crystals".
This book is money well spent. Highly recommended!
