Iolite

Iolite or cordielite is a widespread mineral discovered and named after a French geologist P. Louise Cordiere in 1813. It belongs to the cyclosilicate group rich in aluminium. Iolite is sometimes referred to as the 'Viking's compass' due to its ability to determine the direction of the sun. The property that makes the iolite change color is called pleochroism - the ability to absorb different wavelengths of light depending upon its crystallographic orientation. A cube cut from oolite will look violet-blue from one angle, almost like sapphire, and can be essentially colorless from another angle, and a yellowish-blue from on top. In the past, this property led some people to call Iolite the 'water sapphire'. This material comes from India.

Iolite uniqueness: Iolite is noted for its dark blue-violet shades, in places with light patterns. The high-quality pieces from India are suitable for further processing.
