An especially fine thumbnail of elongated Chalcocite crystals some showing the cogs-wheel form of twinning. From the classic Cornish locality of Levant, which operated from 1793 to 1930 which produced some of the very best of British Chalcocites. This style is quite uncommon from the mine and presents well from all sides. In excellent condition with well-defined form and esthetic composition.

Very fine classic specimen, ex George Robinson collection with sharp, free standing crystals. This specimen is currently pictured on Mindat it is the first specimen in the St Just Bornite section. The shape of the original Chalcocite shows some cyclic twins that are perfectly preserved. Some of the crystals may still have some Chalcocite inside. The exterior shows the patina of Bornite and is quite attractive. In fine condition as seen a choice old classic piece
