Smoky Quartz Tumble
Smoky Quartz (also know as Morion or Cairngorm) is a well known variety of Quartz, characterized by it's brown/grey/black colouration.
This colour comes from the free silicon within the crystal, formed through irradiation of the silicon dioxide. It is possible to have lab coloured smoky quartz (smoky quartz is often irradiated in a lab to enhance it's colour) however these pieces are 100% natural and that is why there is variation in colour.
