11.2" Druzy Green Quartz Geode With Metal Stand - Uruguay
This is a truly stunning specimen of rare green druzy quartz stalactites 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. The quartz formed in stalactitic projections that sit horizontal within the geode when placed on its stand. Calcite crystals can be found scattered within this fascinating geode, as well.
I can pretty much guarantee this incredible piece will look even 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.
