3" Amethyst and Quartz Crystals - Peru

 
This is a lustrous, 3" wide aggregation of quartz and amethyst crystals, collected from the Pisco Province in Peru.

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.
