Quartz is the most common mineral in the Earth's crust and comes in many colors and forms, from magnificent clusters all the way down to a grain of sand.  Quartz is very often clear, but sometimes contains mineral inclusions. Some interesting forms of quartz include Dendritic, Druzy, Fire, Girasol, Golden, Phantom, Rutilated, Spirit, Tourmalinated, and White. Quartz is known as the Master Healer used to amplify energy and thought, as well as the effect of other crystals. Quartz is a great all-purpose crystal as it helps open and balance all Chakras.
