The name, initially used to describe other gems, comes from the island of Topazos, in the Red Sea. Only in 8th century did we start using it for what is the Topaz gem today. The ancient Greeks believed that Topaz gave them strength. In Europe during the Renaissance people thought that Topaz could break magic spells and dispel anger. For centuries, many people in India have believed that topaz worn above the heart assures long life, beauty, and intelligence. Pure Topaz is colorless and transparent, known as allochromatic, and trace elements such as chromium, iron and manganese are responsible for its various tints. Sky Blue Topaz, once rare, is now created using modern processes like irradiation.
