Structurally, it belongs to the inosilicates. Kyanite predominantly develops prismatic to tabular crystals with a glassy luster on the surfaces, but it also occurs in fibrous or granular to massive mineral aggregates. In pure form, kyanite is colorless and transparent. Due to multiple refractions of light caused by lattice defects or polycrystalline development, it can also appear white and, due to trace impurities, take on hues from light- to dark-blue, blue-violet, greenish to brownish and rarely reddish, with transparency accordingly decreasing.
