Iolite
The name iolite comes from the Greek "ios", which means violet. The Vikings probably mined iolite from deposits in Norway and Greenland. Viking sailors used iolite as a polarizing filter to find the sun on cloudy days for safe offshore navigation. Iolite is usually a purplish blue when cut properly, with a softness to the color that is quite attractive. The favorite color is that pretty, 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. In viewing an iolite stone, the colors violet blue, yellow gray and a light blue can be seen; all a result of pleochroism.

Its hardness of 7-7.5 makes iolite a suitable jewelry stone, though the presence of cleavage must be taken into account and some care taken, such as protection from blows. Iolite, a gem variety of the mineral cordierite, is an unusual stone indeed that is not commonly seen in jewelry. Iolite is known as the gemstone for clear vision.

It's pretty great having a whole lot of different gemstones to choose from. When doing crafts and jewelry making, it's great to have all kinds of options, and it's amazing how much cheaper it is to just purchase un-set gemstones and make the setting yourself, as opposed to buying fully-made jewelry already. It's also extra special since you made it yourself.
