Old specimen of native arsenic, forming botryoidal aggregates, with an intense gray color slightly bronze. These specimens were known locally as "scherbenkobalt" (pieces of cobalt). Note that this mine is the Type Locality of the annabergite. A difficult German mineral classic to find from this locality, an old silver and cobalt mine, worked from around 1650 until 1852 and reworked between 1856 and 1859.
