The mineral Kyanite is also called diststeen and belongs to the nesosilicates. The chemical formula of the mineral is Al2(SiO4)O and therefore it is an aluminum oxide. The transparency of the mineral is generally opaque. But kyanite can also be transparent and then it is sometimes used as a gemstone. The color of the mineral is generally blue but the colors green, red, gray, orange and pink are also found. The name comes from the Greek and literally means blue.
