Steinmetzite is a very rare phosphate mineral with formula Zn₂Fe(PO₄)₂(OH)•3H₂O. It was discovered among pegmatites of Hagendorf in Germany,^[4] that are famous for rare phosphate minerals.^[5] Steinmetzite is chemically related to phosphophyllite and other zinc iron phosphates, namely plimerite and zinclipscombite.^{[6] [7]}
