2.8" Epidote Crystal Cluster with Quartz - Peru
This is a beautiful epidote crystal cluster with quartz crystals that formed from an epidote encrusted, pistachio-green matrix. This specimen was collected from Peru, however the specific mine from which it was collected is unknown. Based on the structure of the epidote crystals and the matrix, I'd say it likely came from the Lima Department or Pisco Province of Peru.
Epidote is a green, silicate mineral that is commonly found in regionally metamorphosed rocks. It often forms lustrous, elongated and interconnected crystals that are highly coveted by collectors. While nearly all epidote is green it may take on many different shades and tones from yellowish to deep green.
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.
