Mineral Specimen #3988 Calcite with Included Copper
Quincy Mine, Houghton Co., Michigan
Ex. A. E. Seaman Museum
A very attractive cluster of Calcite crystals with included Copper. The Calcite is very clear and the Copper is brightly colored. The crystals are scalenohedron with flat surfaces with good luster. Classic Quincy Mine material.
The specimen is in fairly good condition but two of the crystals have internal cleaves and some wear on the edges.
