Smoky Quartz is formed as a result of natural irradiation and often has a large constituent of Sodium; the stone is sometimes enhanced by heat treatment - generally speaking when the stone is very dark it is usually safe to assume it has been heat enhanced to give a deeper colour. Sources include Brazil, Switzerland, the Himalayas, and Mexico.
