About Iolite Gemstone

Cordierite is also called Iolite, Dichroite or even “water sapphire” due to its frequent sapphire blue colors. Although Iolite is the widely used name for this gem, Cordierite is the IMA recognized name for the mineral species. Iolite Gemstone has intense and distinct pleochroism showing colors of blue, violet, smokey blue and gray when viewed from different angles. Iolite’s crystal structure is very similar to that of Beryl and is a member of the Beryl series of minerals. Iolite stone rarely contains inclusions of hematite plates that create a beautiful schiller effect.

Although Cordierite is found in many locations worldwide, relatively few produce fine, gem-quality crystals. Some of the better known sources of Iolite gems are Coroaci, Minas Gerais, Southeast Region, Brazil; around Tiruchchirappalli and Coimbatore, Tamil Nadu, India; Tranomaro area, Amboasary Department, Tuléar Province, Madagascar; and from the gem gravels of Sri Lanka.
