Iolite

Iolite


Iolite is normally violet-blue in color, albeit, a sometimes dull blue. The best quality faceted gems can sometimes resemble tanzanite or sapphires. Prior to the 1980s, it was not readily available, but supply has increased, making it a beautiful addition to most jewelry.

It's name is derived from the Greek word for violet. Sometimes misleadingly called a "Water Sapphire" because it looks clear and watery from the side, but can resemble a sapphire when looking at it head on.

Iolite was used by the Vikings on cloudy days as a sort of compass. They were able to locate the position of the sun by looking through thin, clear slices of it. It has properties that acted like a light polarizer and canceled out the mist and haze in the atmosphere.

Iolite gemstones
Deposits are found in Sri Lanka, India, Brazil, Burma, Madagascar, Tanzania and the United States.
