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.
Certified Customer Reviews
Overall Rating -> 10 star ratings
My experience with gemselect was awesome so far. I had a few questions about their website and making orders and they replied quickly and were happy to help. I have not received the items I ordered yet as I just ordered them this morning. Although, I truly feel I am going to be a very happy customer once I do receive my items. Gemselect guarantees all their items and have a great return policy just incase. The have a vast selection of all kinds of stones and not to mention their prices are much better than some other websites. Thanks Gemselect I’ll be doing business here from now on!

Great selection. Love the many learning features like articles and gem information. Prices competitive for natural stones. I do miss not having a selection of lab-made stones, CZ’s, etc, which are useful when price and cost are factors.

Size and Weight

Gems are always measured in Millimeter (mm)

Dimensions are given as;
length x width x depth,
except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size

Note: 1ct = 0.2g
