5" Realistic, Carved Gray Quartz Crystal Skull

This is a 5" long skull carved from gray quartz. It is unclear whether this is true smoky quartz, or whether the gray coloration is caused by mineral inclusions. The craftsmanship on this skull is excellent, with the zygomatic arch, mandible and nasal cavities fully rendered, and the mouth carved in an open position.

About Quartz

Quartz is the name given to silicon dioxide (SiO2) and is the second most abundant mineral in the Earth's crust. Quartz crystals generally grow in silica-rich environments--usually igneous rocks or hydrothermal environments like geothermal waters--at temperatures between 100°C and 450°C, and usually under very high pressure. In either case, crystals will precipitate as temperatures cool, just as ice gradually forms when water freezes. Quartz veins are formed when open fissures are filled with hot water during the closing stages of mountain formation: these veins can be hundreds of millions of years old.
