There are many traditional uses of quartz. Ancient Japanese believed quartz formed from the breath of a white dragon, and regarded it as representing perfection. Australian Aborigines used quartz in rain rituals. Crystals skulls were reportedly made by Atlanteans and are believed by some to be living entities. Clear quartz formed into spheres have been used as crystal balls to predict the future at least since the middle ages. Quartz can be manufactured or imitated. Manufactured quartz is created from the same components as real quartz but is made by man. Imitation quartz varies widely, but is commonly some type of glass with or without coloring or inclusions. Many decorative crystals such as Swarovski crystals are not quartz crystal at all, though they are very beautiful and have their own meanings.
