3.8" Tangerine Quartz Crystal Cluster - Madagascar

 
This is a beautiful, high quality cluster of large "tangerine" quartz crystals on granite from Madagascar. The longest crystal is 3.8" long and overall the piece is 3x2.5". Nice defined tips on these large crystals crystals. Sits nicely on a flat surface.

These clusters are natural and not heat treated or coated. The orange color is due to a combination of Iron, Hematite and Manganese coating the surface of the crystals but may also be present as inclusions within the crystals themselves. A likely cause is a high iron content in the soil where these crystals are found.

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.
