11.2" Druzy Green Quartz Cluster - Uruguay
This is a truly stunning specimen of rare, green druzy quartz from the amethyst mines near Artigas, Uruguay. Sometimes referred to incorrectly as "green amethyst" it was mined from within a pocket in the basalt and features a secondary growth of sparkling, green quartz crystals. I can pretty much guarantee this incredible piece will look better in person than in the photos.
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.
