Cordierite (iolite) characteristics

The cordierite is a stone from the silicate family. It is composed of magnesium silicate and aluminum.

It shows vitreous to matte glints in blue hues where you can see a three color variation according to the angle (pleochroism): blue, yellow and purple.

Its crystals can reach 18cm long. The biggest carved cordierite is located in the British Museum and it weighs 855 carats.

It was described by the mineralogist Lucas in 1813. Its name was given in honor of the French mineralogist Louis Corbier who described it in 1809 under the name of dichroite.

It can be found under the name of dichroite coming from “duo” or “two” and “Kroma” or “color” which refers to its pleochroism.
It commonly appears as Iolite or Volithe (Werner) from the Greek “lol” or “purple” as a reference to the color of the flower with the same name. It can also be found under other names such as New Zealand blue quartz (steinheil), water sapphire (Buffon) or Steinheilite (Pansner).

Cordierite is difficult to identify and can be easily confused with amethyst, quartz, tanzanite or serpentine.

It is insoluble in acid and resists to fire.
