What is Sillimanite?
Sillimanite is an aluminium silicate with the same formula as kyanite but a different crystal structure. It often forms silky, fibrous masses called fibrolite.
India is an important source of sillimanite, which is used both as a collector stone and as a raw material for high-temperature ceramics. Polished pieces can show a cat's-eye effect.
