3.1" Quartz Crystals On Sparkling Bladed Hematite - Lechang Mine
This is an incredible association of quartz crystals with chlorite inclusions, and bladed hematite rosettes (specularite), collected from the Lechang Mine in Guangdong, China. The quartz crystals are all in pristine condition with exceptional clarity.
Hematite is a fairly common mineral, typically responsible for the red-brown coloration that can be found in other minerals and rocks. The chemical composition of hematite is Fe2O3, occasionally containing small amounts of titanium (variable formula (Fe,Ti)2O3). Much of the time, non-crystalline hematite specimens are the result of a transformation from limonite following loss of water.
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.
