Serious Tsumeb collectors and those interested in type localities, this is an important and amazing specimen! The mineral Biehlite is an antimony-arsenic molybdate, first discovered at Tsumeb and then officially approved in 1999. It is exceptionally rare. What makes this small miniature so special is it is part of the Type Specimen, sometime very rare to come across on the mineral market. This specimen comes with a renowned German collector's label who is a highly regarded Tsumeb expert and author and noted on this label is 'part of type'. Even without this provenance, the specimen is a superb example of Biehlite occurring as pure white felt-like mats of fine acicular crystals of up to 1 cm long and richly covering a matrix of opaque snow-white Anglesite crystals. Because Biehlite is such a delicate mineral, the specimen is housed in a rectangular Jousi-style box with clear acrylic lid. A superb and important Tsumeb specimen.
