This book is aimed at those who believe that stones can be harnessed for healing. I believe that any such effect is almost certainly a placebo effect, so that aspect of the book holds little interest for me. What does interest me is the gemstone identification that is provided, which is easily the easiest to use of any book on gemstones that I have encountered. The pictures are very helpful, and the text relating to each gemstone (apart from that related to its healing powers, which admittedly is most of it!) is brief but to the point, describing its likely presentation and source.
