Also called Rock Crystal, is pure silica without any inclusions. All other varieties of Quartz, such as purple Amethyst, yellow Citrine or pink Rose Quartz get their color because of tiny inclusions in the silica. Quartz is one of the most abundant minerals on earth, but good quality Clear Quartz is relatively rare. The best pieces can be fully transparent, clear as glass, or have prisms that create sparkly rainbows. For centuries it was thought to be petrified ice that couldn’t melt! Clear Quartz amplifies the energy of other crystals and can be used for any healing purpose. It can also help us find our own energy and power.
