Smoky Quartz

Smoky Quartz


Here is an old favorite back at the Rock Shed in the crushed rock division.  This is some very nice, high quality Smokey Quartz from Brazil.  It comes in sizes from 1/2″ to 1 1/4+”.  This rock is great for the rock tumbler, use it as is for fountains or other decorative uses.  This is from a fresh new batch of rock that just came in so get some quick before it is gone.

MOHS hardness scale of  7


Quartz is the second most common mineral in the Earth’s continental crust. It is mainly composed of Silica or Silica based minerals. Although Quartz is known by a variety of names, the most important distinction between types of Quartz is that of macro-crystalline, individual crystals visible to the unaided eye, and micro-crystalline, where aggregates of crystals are only visible under high magnification. There are many forms of Quartz including Chalcedony, Amethyst, Citrine, and Carnelian which are results of mineral impurities or heat treatments.rism in transmitted light.
