4.2" Sparking Orange Druzy Quartz Cluster on Wood Base - Uruguay
This is a beautiful, sparkling cluster, of orange, druzy quartz mined Artigas, Uruguay. It comes from the same mines as the dark Amethyst that this area is renowned for, but these orange crystal pockets are a much rarer find. The sides of the specimen have been polished, leaving a beautiful agate "rind" and it comes with a custom-made wooden display base.
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.
