Iolite has a very part to play in History, as it is truly the gemstone of the Vikings. Indeed, when explorer Leif Ericson and his Viking fellows ventured far out into the Atlantic Ocean, they used thin pieces of Iolite as the world's first polarizing filter. Thanks to this Iolite lens, they could determine the exact position of the sun, and ultimately navigate their path safely to the New World and then back.



Iolite is renowned for its strong healing powers, both physical while helping detoxify the body or treat addictions and spiritual while fostering insight and foresight.
