Item Description

Cordierite is probably most well known for it's purple/blue variety called Iolite. Iolite translated from Greek literally means "violet stone". These gems are sometimes known as "water Sapphire" in various corners of the gem world, but it is truly gem grade Cordierite. Iolite is strongly pleochroic and shows a strong blue color one direction, a violet color another direction, and a yellowish color in the third direction. This particular gem is from the Tanzanian gem gravels, where some of the nicest Iolites are being mined these days. The stone is only very very slightly included with an "Emerald" cut, and it does show good pleochroism when rotated on its various axis, but it's hard to illustrate in the photos.
