Quincy Mine, Hancock
This incredibly robust Native Copper from the Quincy Mine offers enormous geometric crystals of the classic material from Michigan. This wonderful example is superlative for the size and nature of many amazing crystals which have seemingly fused together on this hefty mass of colorful metal. The textural exterior is a bit muted in color with a brownish tone that is complemented by bright flashes of Copper that break through the darker "skin" of this complicated specimen. Out of the collection of the noted Midwest collector Robert Nowakowski, this solid form has much to offer visually. The underside has a latticework pattern partially filled with powdery white material that rounds out the unique nature of this varied Native Copper specimen. This mineral should appeal to many Michigan Copper collectors.
