 Mmeko mineral ndi metutara ya bara uru, karisia nke onuno nke polymorphs nke staurolite, nke na-emekari na kyanite.  Otu o di, agwa kasi baa uru n'icheputa kyanite bu ihe anisotropism.  O buru na onye na-enyo enyo na ihe atu nke ga-abu kyanite, na-egosi na o nwere ike abuo di iche na axis perpendicular bu isi maka njirimara, o nwere ike nke 5
