Scarce hydrated lead copper zinc arsenate sulfate, known only from Tsumeb in fine crystals - and this is a rich piece with relatively large microcrystals covering the top surface! A 2.2 x 2.4 x 2.2 cm specimen with tabular to lathe-like <0.5 mm satiny blue-green aggregates. A fine, rich example of this Tsumeb rarity.
