Arsentsumebite is one of the rare lead, copper mineral species for which Tsumeb is famous and is the Type Locality. This is a fine, very rich, two-sided combination specimen with lots of grass-green arsentsumebite, lustrous, contrasting azurite and a bit of lighter green bayldonite on one side. Old material, probably predating the 1920s.
