A stunning miniature! This acanthite replacement after argentite is highlighted by the two crystals at the apex of the specimen. The one on the right is doubly terminated and measures 1.5 cm in length. The one on the left has unusually curved edges and measures 1.8 cm in length - very strange crystal, that is mesmerizing! All the crystals are octahedral, with splendent luster and a jet-black color that is hard to convey because it is lustrous. This is a superb, elegant acanthite by any standard, quite different from Mexican and Chinese and German acanthites we might have seen previously
