Pb2Cu(PO4)(SO4)(OH)
heart IMA grandfathered

Tsumebite is a rare phosphate mineral with the chemical formula lead copper phosphate sulfate hydroxide, Pb2Cu(PO4)(SO4)(OH). It belongs to the orthorhombic crystal system and is classified under the phosphate mineral group. Tsumebite typically exhibits a green streak and has a vitreous to dull luster. Its hardness ranges between 3.5 and 4 on the Mohs scale, and it has a relatively high density due to its lead content. The mineral is known for its complex chemical composition, combining phosphate and sulfate anions in a single structure. It is a member of the Strunz classification 8.BG.05, which includes related phosphate minerals.
