Highly sought after are specimens such as this one from the Herodsfoot mine. As is typical from Heredsfoot, Tetrahedrite crystals are coated with Chalcopyrite. This specimen is no exception with 10 or 12 Tetraherite crystals from 5mm to 1cm in size. All are coated nicely with Chalcopyrite. The matrix is Galena. Comes with a David New label.
