Quartz is one of the most common minerals found in the Earth's crust, and takes on a variety of colors depending on the other minerals and trace elements that are included as it forms and grows. Smoky quartz gets its color when aluminum impurities in rock crystal quartz are activated by natural geological radiation over long periods of time.
