H5E-E5MDolomite (Var: Cobaltoan Dolomite) : (Ca,Mg,Co)CO3, Wulfenite : Pb(MoO4)Tsumeb Mine, Tsumeb, Oshikoto Region, Namibia
This wonderful Tsumeb combo piece consists of a matrix of dolomite that has been colored pink, presumably by cobalt. On it sit several beige colored crystals of wulfenite. One stout central crystal dominates the piece resulting in a very unique type specimen that only Tsumeb could produce. The contrast of colors and the orientation of the wulfenite crystals result in a composition that is aesthetic and quite pleasing to the beholder. The dolomite itself is a cast or epimorph of another mineral generally thought to be calcite.
It measures 7.8 cm long by 4.5 cm wide by 2.5 cm tall. The main wulfenite crystal measures 1.9 cm tall by 1.6 cm wide by 0.8 cm thick.
