EULYTINE

SPECIMEN DESCRIPTION

This is a lovely old-time miniature Eulytine from the Type Locality at Schneeberg, Erzgebirge, Saxony, Germany. A rusty, gossanous matrix has a cavity richly invested with over a hundred dark brown to black glossy microcrystals of Eulytine, some displaying the perfect tetrahedral habit. An accompanying old handwritten label uses the name "Kieselwismut" which was widely used during the second half of the 19th century. From the superb systematic collection assembled by the brothers Martin and Michael Günther (1951-2007 & 1956-2021).
