Natural Iolite
Also called Dichroite, Iolite is a blue silicate mineral that occurs as crystals or grains in igneous rocks, only as a result of contamination of the magma by aluminous sediment. When clean, blue iolite is sometimes cut as a gem; the stones from the gem gravels of Sri Lanka have been called water sapphires. Iolite has enjoyed a recent resurgence in popularity due to its affordability and similarity to tanzanite and sapphire at a much lower price. |
