3.65" Double-Terminated Smoky Quartz Crystal with Phantom - Poland
This is a natural, double-terminated, smoky quartz crystal that contains a beautiful smoky phantom within, collected from Strzegom (Striegau), Poland. There is some citrine coloration along each end of this crystal.
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.
