Cunningham's Encyclopedia of Crystal, Gem, and Metal Magic
by Scott Cunningham
The late Scott Cunningham had a remarkable talent for compiling information into clear and readable accounts, such as his works on herbs,oils, incense, foods, etc. This book is no exception, as he offers an exhaustive encyclopedia about the magical properties of gems and precious metals. He provides a succinct history of the uses of each stone, its folklore, the deities it represents, and its magical uses. His bibliographies are always appreciated, as they are annotated, and offer a very helpful guide to further reading.
