Epic 10.4" Smoky Quartz Cluster WIth Calcite - Brazil

This is an epic cluster of dark black, smoky quartz crystals from Brazil. The entire plate is 10.4 inches wide and the longest point is over 5 inches long. There are small, honey-yellow calcite crystals in between many of the points. Excellent quality crystals with great terminations and very little chipping. The black coloration goes all the way down to the granite matrix. It has not been heated or treated to change the natural color.

Smoky quartz is a grey-brown to black variety of quartz. This common name is derived from the appearance of smoke within the quartz crystal. Depending on the location and the chemicals present during formation, smoky quartz can appear opaque black, but it is typically translucent to some extent. It is believed that the quartz gains this color from a combination of natural irradiation and aluminum impurities.
