The polarizing filter of Iolite was first used by the Viking mariners as it extracted the sun's position for them to navigate safely.

A water Sapphire Gemstone in its deep Blue Sapphire color is the other name for Iolite. Just like its fellow Blue Gemstones Sapphire and Tanzanite, Iolite is pleochroic- as it spreads light differently when observed from different directions.

There are some sacred texts in which Iolite Gem is also known as Neeli as its powers are considered equally to Blue Sapphire. Iolite was named after a French geologist - Cordier. Iolite does precisely what a Polaroid do: it eliminates steam, vapor, and clouds to form things seem more open. The Gemstone has been cherished and utilized for a hundred years and divulged about in every jewelry within the eighteen century in Europe but to the latest, it is used moderately sometimes.
