Aura Quartz Crystals go through a process to electrostatically bond a Clear Quartz Crystal with a coating of precious metals from the earth like platinum and silver, or sometimes gold. Through this process, a new, unified colour layer is created on top of the original Crystal, making a permanent blend that intensifies the properties of the original elements. As a result, Aura Quartz Crystals emanate a unique spectrum of lovely subtle energies.
