15.7" Druzy Green Quartz Cluster With Metal Stand - 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 even better in person than in the photos. Please watch the video to see how truly dazzling this cluster is.
Silicon Dioxide, also know as SiO2 or Quartz, is the second most abundant mineral in the Earth's crust. Quartz crystals generally grow in silica-rich, hot watery solutions called hydrothermal environments, at temperatures between 100°C and 450°C, and usually under very high pressure. Quartz veins are formed when open fissures are filled with hot water during the closing stages of mountains forming, and can be hundreds of millions of years old.
