Iolite comes in different colors in different directions in the crystal. An Iolite cube will look violet blue, like Tanzanite from one side, colorless from the other, and a yellow from top.Iolites are extremely difficult to cut- to display the best color, due to the Pleochroism When Leif Eriksson the legendary Viking explorers ventured into the Atlantic, the Viking mariners used thin pieces of it as the world\'s first polarizing filter, to determine their position for navigation. Extreme Pleochroism - is the property which made iolite so valuable to the Vikings.
