One of our "go-to" reference books. This handy guide to the stones describe their physical characteristics, and then delves deep into the metaphysical properties of over 300 stones, gems, crystals and minerals. Also includes information on "companion stones", those that pair well with the stone being described. Excellent photos of all the entries. Information regarding chakra centers, physical ailments, elements, keywords and spiritual uses are all presented in a very readable and comprehensible format. No matter how much you know about stones and crystals, this book is an extremely valuable aid to learn more!
