Cafarsite (Type Locality)

Item Description

Cafarsite is an ultra rare, hydrated arsenite and this very fine thumbnail specimen is from the Type Locality area in the Binn Valley of Switzerland. The dark sub-metallic, grey-brown crystals with nifty reddish highlights are well formed modified cubes with octahedral faces. The crystals reach 7 mm. This is an outstanding example of species. Cafarsite was not discovered until 1966. This is a superb representative specimen
