Bismuth
Locality: Pöhla-Tellerhäuser Mine, Pöhla, Schwarzenberg District, Erzgebirge, Saxony, (Locality at mindat.org)
Size: 6.8 x 4.5 x 3.1 cm.
"Federwismuth," as the Germans called it - this is CLASSIC crystallized native bismuth from the Pohla Mine, possibly dating back more than 100 years although they were found in small pockets of the quarry as recently as the 1970s I am told. This particular specimen has a mesmerizingly complex display face with sharp "feathers" of stepped, elongated crystals to 2.5 cm, capping a knoll of ore matrix. From the collection of well-known German collector, Paul Stahl.
