Cordierite a Pleochroic Mineral

A Pleochroic Mineral with a Blue-Violet Hue

Cordierite is a silicate mineral found in metamorphic and igneous rocks. It has a blue to violet hue and is one of the most strongly pleochroic minerals. Pleochroism is the phenomenon where materials appear to have different colours when viewed from different directions. Transparent cordierite (iolite) can be both blue and yellow from different angles.

Iolite or cordierite?

The name "Cordierite" is used by geologists to refer to the mineral. In gemology, they call the transparent variant of Cordierite "iolite". Two older names for the mineral are "dichroite" and "water sapphire". The name dichroite means "two-coloured stone" and is inspired by the pleochroic property of Cordierite. The name watersapphire is also related to pleochroism. It was used because a specimen could have the colour of a sapphire when viewed from one direction, but if the stone was turned, it could be as clear as water.
