Gemstones and glittering minerals have fascinated people for thousands of years. This volume explores the mythology of gems; it is not a technical field guide. It looks at how humankind has used and exploited these stones throughout the ages and across the world, not just for their beauty, but also for the magical powers many believe they possess. Myths and legends about the most popular gems, rocks and crystals are revealed and retold. A comprehensive reference section gives technical data on the featured stones identified by mineralogists.
