Iolite

India
Iolite is the gem variety of the mineral cordierite. It is frequently confused with sapphire due to its rich blue hue. Usually the pleochroism is very pronuounced in iolite and three different colors can be seen in the same stone—violet blue, gray and a lighter blue can be seen depending on the angle of sight. This rectangular-cut iolite is an exceptional example of the mineral species with its strong violet-blue color, unmasked by either grey or black (as is typically the case), exceptional clarity and luster. An excellent stone for the serious collector. Weighing approximately 11.18 carats and measuring 14.8 x 11.6 x 9.6mm.
