About Iolite Gemstone

Cordierite is also called Iolite, Dichroite or even “water sapphire” due to its frequent sapphire blue colours. Although Iolite is the widely used name for this gem, Cordierite is the IMA recognised name for the mineral species. Iolite has intense and distinct pleochroism showing colours of blue, violet, smokey blue and grey when viewed from different angles. Hardness of iolite is 7-7.5 makes iolite a suitable jewellery stone, though the presence of cleavage must be taken into account and some care taken, such as protection from blows. Iolite’s crystal structure is very similar to that of Beryl and is a member of the Beryl series of minerals. Iolite 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.
