Healing Crystals: the A to Z Guide to 430 Gemstones by Michael Gienger

What a great book! Concise, informative text with more detail than you might expect in a pocket volume, plus photographs of the average specimen rather than the museum or collector pieces featured in most gem texts. Each entry gives an idea of the many uses of the stone: spiritual, mental, physical and soul aspects are addressed for over 400 different minerals.
