3" Realistic, Polished Brazilian Quartz Crystal Skull

This is a 3" long, polished quartz skull from Brazil. This quartz specimen has undergone intricate sculpting and polishing that left the crystal in the shape of a skull. There is some slight pink coloration to the quartz, however not enough to comfortably label as rose 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.
