This is a 2.8" long, natural double smoky quartz crystal points from Brazil. Nice terminations with only some minor dings. The main crystal point in the cluster is over 1.5" thick! The crystals are more cloudy at the base, getting darker near the tips. The color is natural and the crystals have not been heated or treated. Very good quality crystals.
Smoky quartz is a grey-brown to black variety of quartz. This common name is derived from from the appearance of smoke within the quartz crystal. Dependent on the location and the chemicals present during formation, smoky quartz can appear opaque black, however it’s typically translucent to some extent. It’s believed that the quartz gains this color from a combination of natural irradiation and aluminum impurities.
