Iolite has different colours in different directions in the crystal. A cube cut from iolite will look a more or less violet blue, almost like sapphire, from one side, clear as water from the other, and a honey yellow from on top. In the past, this property led some people to call iolite 'water sapphire', though the name is now obsolete.

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.
