Tsumeb mine, Tsumeb, Otjikoto Region, Namibia
Miniature, 4.0 x 2.5 x 1.3 cm
A superb miniature specimen consisting of lustrous, yellow-tan, hexagonal, prismatic crystals of hedyphane with pyramidal terminations. The large cluster with very distinct crystals consists of individuals that are 2 to 7mm in length. This could be easily confused with mimetite as some of the early specimen labels from this occurrence indicate. Hedyphane is an uncommon lead calcium chloroarsenate and these represent some of the better crystals for the species, which is why they can be confused with mimetite when they are thi big and good (similar chemistry, different crystal habit). An EDS analysis accompanies the piece for confirmation. This is one of the rare, legitimized hedyphanes and is an important, rare species for Tsumeb.
