This is a truly outstanding Långban miniature of a phenomenally rare species: Finnemanite. This lead chloroarsenite species was first described from Långban in 1923 and, in the century since then, has only be recorded from four other localities, two of which are considered dubious. It cannot be described as the most glamorous of minerals, but this wonderful specimen is one of the finest examples known outside of major museums. It comes from the outstanding systematic species collection assembled by brothers Martin and Michael Günther (1951-2007 & 1956-2021) and features a series of parallel dark purple-grey Finnemanite crystals embedded in an unidentified cream coloured matrix and fine-grained Hematite. The crystals reach a staggering 1.5 cm x 0.2 cm and there are several of them. A "next level" piece for the dedicated rare species enthusiast.
