This interesting thumbnail specimen features an 8-mm, pseudocubic native bismuth crystal highlighted by a thin veneer of splendent, silver colored joseite on it. Wolframite and quartz make up the matrix. From the Harding vein, Carrock Mine. Ex. Barstow and Sutcliffe collections with their accompanting labels. This is an extreme rarity for the north of England, and a fine crystal in any case. Joe Budd photo, atop. SUPER rare example of this species, from the British Isles.
