Quartz is the most common mineral on Earth. It has a hard glassy surface and occurs in many shapes and colors. Clear quartz is found in masses, in clusters or as points, which are pieces of clusters. Quartz generates an electrical charge and has many scientific, industrial and metaphysical uses. This tumbled variety is smooth and translucent, giving it a very beautiful appearance.
