14.5" Wide Tangerine Quartz Crystal Cluster - Madagascar

 
 
 
This is a beautiful and massive cluster of "tangerine" quartz crystals, from Madagascar. The entire plate is 14.5" long and up to 10.9" wide. The longest crystal on the piece is about 3.7" from its base to the tip. There is beautiful coloration and sharp crystals on this spectacular plate with nice variety in crystal sizes.

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.
