This specimen is a fragment of a galena/carbonate vein. On a couple of sides there is a coating of crystallized silver that, in open spaces manifests itself as wires. They are small but there is lots of silver on it! The galena is relatively fine grained and embedded in the carbonate. There are also small pyrite crystals embedded in the carbonate. The label says "argentite" as well but I cannot see any. Could be! It is accompanied by an antique Harvard Mineralogical Museum label.
