Description All of our Minerals & Crystals are 100% Genuine Specimens & come with a Certificate of Authenticity Smoky Quartz is a colour-variety of crystalline quartz. It ranges from a light yellowish brown to a brown that is so dark that it appears to be black. The colour of smoky quartz is produced when natural radiation, emitted from the surrounding rock, activates colour centres around aluminium impurities within the crystalline quartz.
