Richly adorned specimen of acicular metallic grey crystals of Bismuthinite line numerous cavities in a Chalcopyrite, Quartz matrix. Add interest to the specimen are later depositions of balls and botryoidal zoned brown Cassiterite 'Wood Tin', with very dark green Chlorite grown on the Bismuthinite crystals. A fine specimen from the Fowey Consols Mine, Tywardreath, Cornwall, and a rare combination.
