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 aspoints, which are pieces of clusters. Quartz generates an electrical charge and has many scientific, industrial and metaphysical uses.  Quartz can manifest in a huge variety of different forms, each with its own color.  This particular specimen is an example of smoky quartz, which is a is a grey, translucent variety of quartz.  It ranges in clarity from almost complete transparency to a brownish-gray crystal that is practically opaque.
