5.1" Realistic, Polished Quartz Crystal Skull

This is a 5.1" long, polished quartz crystal skull from Madagascar. This quartz specimen has undergone intricate sculpting and polishing that left the crystal in the shape of a skull. The underside of the skull and the nostrils have been hollowed-out, making the specimen closer in resemblance to a real skull.

This skull contains an interesting red flake within the quartz, likely a result of hematite.

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.
