3.45" Polished Tourmalinated Quartz Crystal Sphere - Brazil

This is a 3.45" wide sphere made from tourmalinated quartz from Minas Gerais, Brazil. The entire sphere has been polished to a glossy finish and the orange coloration along natural fractures in the sphere can be attributed to iron oxidation.

Comes with the pictured display stand.

Silicon Dioxide, also known 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.
