4.9" Wide, Silvery Druzy Quartz Cluster - Uruguay

 
This is a specimen of a silver colored, quartz cluster from the amethyst mines near Artigas, Uruguay. It was mined from within a pocket in the basalt. The quartz is actually colorless and it is the dark matrix beneath that gives it the appearance of being a silver-brown color. Comes with a removable wood stand for display. The edges of this cluster have been polished to reveal the stunning deep mineral formations.

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.
