A superb group of very sharp spinel-law twinned copper crystals associated with minor white baryte from the South Kearsarge Mine in Michigan’s Upper Peninsula Copper District. Unusually-sharp and complex spinel law style copper crystallization for Michigan copper, especially at this locality. This fine specimen has passed through numerous notable collections over the years. One clean repair near the base. Mark Cross photo. Rare!
