3.1" Double-Terminated, Lustrous Smoky Quartz Crystal - Brazil

Double-Terminated, Lustrous Smoky Quartz Crystal - Brazil #256443

This is a natural, double-terminated smoky quartz crystal from Minas Gerais, Brazil. This type of smoky quartz is commonly marketed as "smoky elestial quartz", or in some cases "jacaré" (Portuguese word for alligator) quartz for some specimens' resemblance to alligator skin. It has a glassy luster and excellent transparency.

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.
