30mm x 29mm x 12mm
A good single Bournonite crystal with classic tabular form, good luster and relatively sharp faces. The alternating smooth and striated faces along with the metallic silver color and minor associated micro grey/white Quartz make this a good little reference specimen from this classic locality.
