While the famous Fresnillo Mining District in Mexico's Zacatecas State has long been known for superb examples of silver minerals, these acanthite crystals are truly something special. Their large size, complex crystal development, and sharp, jet-black faces rank them with some of the finest acanthites ever found. This specimen features large, cubic to hoppered crystals associated with small stephanite crystals on selective faces which add a pleasing contrast and association. There is also a fairly sharp ~2.4 cm polybasite crystal on the left side of the piece, which makes for an unusual and desirable association for this find. This is an excellent acanthite specimen for the serious collector, from a small find unlikely to be rivaled any time soon. Tom Spann photo.
