  Copper crystals

Northwestern mine
Keweenaw County
Michigan

Fabulous miniature with copper cubes sitting in a calcite matrix. Steve collected this specimen in 1984 from the hi-grade ore pile that had been stamped for its copper content at the Northwestern #4. We sold it to Richard Whiteman (Red Metal Minerals) in 1985, who sold it to a collector the same year and with whom it remained the past 32 years until we had the chance to acquire it again a month ago. This specimen was mined in the early 1850s and is the best of the cubic coppers we found over the years at the Northwestern.

4.5 x 3.5 x 2.7cm
