Biehlite is a very rare antimony-arsenic molybdate/molybdite and Tsumeb is the type and only locality for the species! This piece consists of a myriad of bright white, acicular crystals in fibrous felted masses on a matrix of solid Biehlite. This is an outstanding large and rich thumbnail of this super rare species that was found only in the third oxidation zone, in a few small pockets. Biehlite was described in 1999 so it doesn't appear in any of the major works on Tsumeb prior to that year. This specimen is mounted on putty and then on a piece of plexiglass for stability and protection. Ex. Marshall Sussman collection. Hand delivery is obviously preferred. It is sturdier than it looks, and you can poke it with a finger, but it is still made like a cluster of fiber and more delicate than other specimens here. In the past, some 1 cm specimens were available, and this would be considered large and rich.
