Iolite gets its name from its color — derived from the Greek word "ios," meaning violet. It is the gem variety of the mineral Cordierite and combines the intuition of the violet ray with the trust of the pure blue ray.
It is said to bring wisdom, truth, dignity and spiritual mastery.
Iolite is sometimes referred to as the Viking's compass, as the stone’s light polarizer \ helped Viking sailors navigate when the sun was hidden by clouds.
Iolite is also the 21st wedding anniversary stone.
