5.5" Natural Red Quartz Crystal Cluster - Morocco

 
 
This is a beautiful cluster of natural red quartz crystals from Tinejdad, Morocco. The red coloration is due to iron oxidation coating the exterior of the crystals. There appears to be a spherical formation of bladed barite on one of the quartz crystals, along with aggregations across what could be considered the underside of the specimen.

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.

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.
