Iolite is the gem name for cordierite, a silicate of aluminum and magnesium. Sometimes called dichroite, alluding to its dichroic properties, it shows two or more colors according to the direction in which it is viewed through transmitted light. Most iolite is found in gravel beds in the form of water-worn pebbles.
