3.3" Quartz Crystal Encrusted Shattuckite - Congo

This is a beautiful quartz crystal encrusted shattuckite formation from the Democratic Republic of the Congo. It comes with an acrylic display stand.

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.

Shattuckite is a scarce copper mineral highly regarded for its vivid blue color. It is named after the Shattuck Mine in Bisbee, Arizona, where this mineral was first discovered. It crystallizes in the orthorhombic–dipyramidal crystal system and usually occurs in a granular massive form or as fibrous acicular crystals.
