Iolite: History & Origin

“Legend says Vikings used iolite as a polarizing filter to guide their ships safely under cloudy skies.”

Iolite, also called “water sapphire,” is mainly found in India, Sri Lanka, Mozambique, Brazil, and Myanmar. Its strong pleochroism means you may see blue, violet, or even pale yellow in one gem. Iolite’s navigational use is celebrated in Norse legend and modern gemology alike.
