Mineral ini tergolong dalam sistem kristal Orthorhombi-dipyramidal. Sebagian besar sillimanite mengandung inklusi jarum halus (needles inclusion) sehingga menampilkan fenomena chatoyancy (cat's eye effect) yang menarik dengan sebaran warna mulai dari colorless (bening), putih, kuning, coklat dan hijau.
