Iolite is also known as and mineralogically referred to as Cordierite, which was discovered in 1813 and named after the French geologist Louis Cordier (1777–1861). A magnesium aluminium silicate, Iolite is a blue silicate mineral that occurs as crystals or grains in igneous rocks as a result of contamination of the magma by aluminous sediment. It has a pleasing blue colour with a rather extraordinary optical property – the gemstone changes colour depending upon which angle it is viewed from. It has a hardness factor of 7.5.
The name Iolite comes from the Greek 'ion' which means violet. Another old name is Dichroite, a Greek word meaning ‘two-coloured rock’, a reference to its strong pleochroism. It has also been called ‘water-sapphire’ and is known as The Vikings' Compass because of its usefulness in determining the direction of the sun on overcast days. This works by determining the direction of polarization of the sky overhead. The Viking mariners used thin pieces of it as the world's first polarising filter. Looking through an Iolite lens, they were able to determine the exact position of the sun, and navigate their way safely to the New World and back.
In the past Shamans wore Iolite to insure the accuracy of their visions and to enhance their clairvoyance. Ancients believed that it could unlock creativity in an artist.
