A classic, old-time specimen from Michigan's Copper Country. Copper in calcite pieces have always been one of the most sought after mineral species from this historic district. This superb piece features copper in calcite crystals on both sides of the gossan matrix, which is richly coated with two generations of epidote. The "A" side has a gorgeous cluster of glassy, transparent calcite crystals with super patina included copper. The two-parallel-growth crystals are doubly terminated and are 3.7 cm long. The calcite cluster on the "B" side also has gemmy and lustrous crystals and the matrix has a rich coating of the two generations of epidote. Another striking feature of this fine piece are the discrete micro copper crystals scattered about on both sides. Specimens of this quality probably date from around 1900 or earlier. Ex. John Ydren Collection.
