It seems as if a matrix of calcite is overlain by radiating, acicular groups of colorless willemite; but actually the "calcite" is cobaltoan adamite which is very rare for Tsumeb. The cobalt-rich and decidedly pink adamite grades into a second generation of light green cuprian adamite, with a rare pyramidal-looking crystal form. Ex. Willy Israel Collection.
