Description: A beautifully crystallized and very colorful Copper specimen that consists of branching, arborescent spinel law twins that form a large 3 3/4" grouping from the long closed Central mine. The patina on this specimen displays lovely Blue Tenorite that "stripes" one side and nearly covers the other. A killer Michigan Copper specimen!
