4.8" Polished Quartz "Stalactite" Cluster On Wood Base - Uruguay

This is a gorgeous quartz "stalactite" cluster formation from the famous mines near Artigas, Uruguay. This specimen comes with a removable wood base that it sits in for display. Some of the stalactite formations have been cut and polished to a mirror finish, allowing for presentation of the stalactite's interior mineral layer 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.
