An interesting mineralogical specimen showing the nature of deposition. There are literally hundreds of tiny, less than 1mm, black Ferberite crystals across the face. Tilting the specimen to the side reveals a thin vein of mineralization which carried the tungsten ore in an open space allowing for full development of the crystals. Small yes, but perfect little crystals with many faces and good luster.
It was collected in 1963 by Hampson.
