2.3" Sage-Green Quartz Crystal Cluster - Mongolia
This is a beautiful cluster of sage-green quartz crystals that were collected from Inner Mongolia. The surfaces of these crystals are covered in smaller quartz growths, giving the crystals a bumpy structure and wet appearance. Most of the green quartz out of Mongolia is a result of hedenbergite inclusions. While this crystal doesn't contain any visible inclusions, the green color is likely still a result of hedenbergite. Other trade names for these specimens are "bluish-green quartz" and "Mongolian Elestial Quartz".

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.
