Cordierite belongs to the silicate family and is composed of magnesium silicate and aluminum silicate. It is a fine stone with different shades of blue, even going as far as purple.

Cordierite exhibits pronounced pleochroism and has various colors depending on the direction of the light rays passing through it and the viewing angle. These are blue, purple and yellow. Sometimes colorless and gray are also distinguished. You just have to move the stone to see its magnificent reflections.

This particularity earned it the name dichroite, (duo for two and chroma for color), which is not the only name given to it. In Anglo-Saxon countries, it is called “iolite” or “volithe” in reference to “iol”, meaning “violet”. It can also be referred to as New Zealand Blue Quartz, Blue Sapphire (nowadays, this name is prohibited, leading to confusion with sapphire) or Steinheilite (a word created by the mineralogist Pansner in 1815 in homage to Count Steinheil, Governor of Finland).

Eventually, in France, this stone was called cordierite by the mineralogist Lucas, referring to the French mineralogist Louis Cordier, who described it in 1809 under its first name dichroite.
