Although there may not be an definite date for when quartz crystals have been welcomed into civilization, the formation of the stones and crystals and the mineral revolution suggest that they have been used since the beginning of mankind.
The first historical reference of crystals comes from Ancient Sumerians, who used the gems and stones as an aid magic formulas, as well as jewelry. Ancient Egyptians would use minerals such as clear quartz, emerald, carnelian and turquoise to create amulets. They believed the stones were a great source of protection and health. The amulets also stood for religious meaning and and self-expression. The Ancient Greeks are a source of a number of properties to crystals and many names we use today are of Greek origin. The word ‘crystal’ comes from the Greek word for ice, as it was believed that clear quartz was water that had frozen so deeply that it would always remain solid. The word amethyst means ‘not drunken’ and was worn as an amulet to prevent both drunkenness and hangovers.
In Native American folklore, it was believed that there were 13 ancient crystals skulls that sang or spoke. The skulls supposedly held important and divine information about the origin, purpose, and destiny of mankind. This legend has been handed down through generations of many Native American tribes over thousands of years including the Mayan, Aztec, Pueblo, Navajo, Cherokee, and Seneca.
As the legends and research became even more popularized, the use of crystals has spread through many different time periods, such as the fall of Atlantis, the Renaissance, and all the way to modern culture.
There has been no research to buttress the notion that crystals do hold any significant healing power, but it is quite clear that crystals have been used since the beginning of mankind and is a large part of history.
