Crystal Quartz
Quartz can be icy clear or have inclusions, veils, bubbles and various colors. It is also known as rock crystal, crystal quartz, universal crystal or clear quartz. People in the earliest recorded times believed in the magical powers of quartz. Ancient Roman, Egyptian and Greek civilizations used quartz crystals as potent talismans. The word quartz is thought to come from the German word "quarz," and the word crystal comes from the Greek word "krystallos," which means ice.
