Iolite. Also know as a Water Sapphire. The name Iolite comes from the Greek "ios", which means violet. Viking sailors used Iolite as a polarizing filter to find the sun on cloudy days for a safe offshore navigation.

Iolite :: An interesting result of iolite's pleochroism is that it is possible to determine the direction of the sun on an overcast day using iolite, by virtue of its ability to distinguish the direction of polarization of light. For this reason, iolite has also been nicknamed "Viking's Compass": There's an old legend that the Vikings & other seafarers of ancient times had a "gem compass" - & that they may have used thin slices of iolite as lenses which aided navigation.

Iolite (cordierite), is usually a purplish blue when cut properly, with a softness to the color that can be quite attractive. The best color is a lovely violet blue that is unlike other gemstones. Pleochroism is very pronounced in iolite and is seen as three different color shades in the same stone. Depending on the viewing angle, iolite will display violet blue, yellow gray or a light blue.  Its hardness of 7-7.5 makes it a suitable jewelry stone.

Bloodshot Iolite. Known as the gemstone of the Vikings, Iolite was used by Norse and Viking explorers as a navigational aid, as a properly oriented stone would change color in relation to the direction of sunlight, allowing for crude navigation in the fog- enshrouded northern Atlantic waters where the direction of the sun was otherwise impossible to discern.
