Description

A rib of very pale green sub-botryoidal smithsonite hosts pseudomorphs of malachite after prismatic azurite crystals (to 25 mm).

The specimen is from the collection purchased by Charles Palache during his visit to Tsumeb in December 1922, which dates it to the upper part of the first oxidation zone (i.e. 8 Level or above).
