In 1813, Cordierite was first discovered in Níjar, a Spanish municipality in the province of Almería, Andalusia. It was named after Louis Cordier, a French geologist, and mineralogist. It was believed that thin slices of Iolites were used by ancient Vikings as filters to help locate the sun on cloudy days. Iolite is derived from the ancient Greek word "ios" which means "violet" in reference to its color.
Cordierite commonly occurs in altered aluminous rocks, igneous rocks, and alluvial gravels. It also occurs in schist and gneiss. In schist and gneiss, it forms during regional metamorphism of shales and other argillaceous rocks. These minerals are also found in hornfels and forms during contact metamorphism.
The chemical formula of Cordierite is (Mg, Fe)2Al3(AlSi5O18). These stones have a hardness of 7-7.5 on the Mohs scale.
The only variety of Cordierite is Iolite.
The price of Cordierite or Iolite can vary anywhere from $20 to $80 according to its color and quality.
