The Vikings used thin slices of Iolite as a light polarizer to locate the exact position of the sun on overcast days. The polarizing nature cancels out haze, mist, and clouds to make things appear clearer.
Shamans would use little pieces of iolite to have visions and communicate with spiritual realms. Iolite is said to increase the holder’s ability to communicate clearly. Shamanic ceremonies vary between cultures but using Iolite was common. Iolite are stones of vision to aid with out of the body journey. Their energy will aid connecting with angels and take you to a higher level spiritually.
