== Characteristics == Aminoffite is a silicate with the chemical formula Ca2(Be,Al)(Si2O7)(H2O,OH). It crystallizes in the tetragonal system. Its hardness on the Mohs scale is between 5.5 and 6. According to the Nickel–Strunz classification, the aminoffite belongs to "09.BH - Sorosilicates with anions Si3O10, Si4O11, etc.; cations in tetrahedral coordination and greater coordination' along with the minerals kinoite, akatoreite, and fencooperite.
