copper for sale spinel law twin Item# CU-3
Keweenaw County, Michigan
Size: 3 3/4"X 3"
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!
