Arthurite is a mineral with the chemical formula CuFe23+[(OH,O)|(AsO4,PO4,SO4)]2·4H2O[1]

In the monoclinic crystal system, it is apple-green in colour, with a Mohs hardness of 3-4, and a vitreous lustre.[1]

Arthurite is named for the mineralogists Sir Arthur Russell and Arthur W. G. Kingsbury. [1]
