Softly shimmering in moody shades of violet, blue and grey, iolite is a guiding stone believed to offer vision, perspective and self-assurance. Read on to learn more about this alternative birthstone for September and its mystical, light polarising properties!

How and where iolite is formed

A variety of the mineral cordierite, iolite is a magnesium aluminium silicate, typically formed in metamorphic and igneous rocks. Originally discovered in Wyoming USA it is now sourced from numerous locations all over the world. Often referred to as ‘water sapphire’, iolite’s name originates from the Greek word ‘ios’ meaning violet. 

Like fellow blue/purple stones sapphire and tanzanite (both of which it is often mistaken for), iolite exhibits different colours when viewed from different angles. This dazzling effect is due to an optical phenomenon known as pleochroism, and is especially noticeable in polarised light.
