Blue Smoke Quartz

Known as a rare, water-clear variety of quartz mined primarily in the Santander and Boyacá provinces of Colombia, notably around La Belleza and the Milton Mine. Blue Smoke quartz is identified by the bluish smoke, or mist, seen swirling around in the clear portions. Sometimes very subtle, other times presenting a deep color, the blue is possibly from water-filled nanotubes left by dissolved minerals. The warm colored inclusions at the base impart a different luster to those portions of the crystal point and are possibly indicative of halloysite.
