Iolite Crystals from India

Iolite is the gem variety of the mineral cordierite.  Although classified and named in 1813 it's believed to have been known and used in Sri Lanka long before then.

One of the most notable characteristics of iolite is its exceptional pleochroism. This characteristic enables a crystal to exhibit different colours when viewed from different angles.

Iolite grades 7 to 7.5 on Mohs scale of mineral hardness.  Despite being quite a hard material it can break quite easily.

Although regarded as "tumbled stones" these pieces have been cut and polished by hand as opposed to being produced in a rock tumbler. Some do have minor anomalies which is not unusual when as stone as hard as this is polished by hand.    

Although colour can vary, iolite is best known for being a blue to bluish-violet coloured gemstone.  The name comes from the Greek "ios" meaning violet.

Our iolite tumbled stones are ideal for display purposes or can also be used for their healing properties.  They're a size medium but size can vary from piece to piece.
