Massive, 15.5" Long Smoky Quartz Point - Brazil
This is an absolutely massive, 15.5" long, smoky quartz crystal point from the mines in Minas Gerais, Brazil. The main point is an astounding 6.7" wide and has an excellent termination. The coloration is natural, the crystals have not been heated, treated or polished. A very impressive display piece.
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.
