Kyanit se yon manm nan seri a aluminozilikat, ki gen ladan tou andalouzit a polimorf ak silimanit nan polimorf. Kyanit se fòtman anizotrop, nan ki dite li yo varye depandan sou direksyon kristalografik li yo. Nan kyanit, ka anisotropism sa a dwe konsidere kòm yon karakteristik idantifye.

Kyanite is a member of the aluminosilicate series, which also includes the polymorph andalusite and the polymorph sillimanite. Kyanite is strongly anisotropic, in that its hardness varies depending on its crystallographic direction. In kyanite, this anisotropism can be considered an identifying characteristic.
