This book is a study of the symbolism of precious stones, and how they have been used as magical objects through the ages, both intrinsically, and as a vehicle for symbolic engravings. The Pavitts cover Hindu, Jewish, Chinese, Egyptian, Roman, Gnostic, and Christian lore of gems. The final section discusses the astrological connections of key gems, sign by sign. This work also includes quite a bit of history of important (and often 'cursed') stones such as the Hope diamond, and practical advice about purchasing gems.
