Kyanite is a silicate mineral with the chemical formula Al2SiO5. It's known to be one of the most attractive natural minerals in the world, frequently found with lustrous blue bladed crystals, with the intensity of color varying by location of extraction. Kyanite regularly forms fibrous, radiating crystals, as well as flattened and tabular. Some crystals form with white striations, color bands, and even multi-colored crystals, though typically found with a deep blue streak running down the middle.
