5.8" Carved, Smoky Quartz Crystal Skull
This is a 5.8" long, polished smoky quartz skull from Madagascar. This skull has been sculpted and polished from a larger chunk of smoky quartz.
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.
