Calcite With Native Copper Inclusions

One of the sought after mineral combinations from the copper mining area of Houghton Co, Michigan, USA. The specimen we have is from the Franklin Mine (closed 1880, later absorbed into the Quincy Mining Company ). A translucent to gemmy terminated multi-faced crystal of Calcite stands upright measuring to 4.2cm tall on the specimen. It is heavily included by sheets of coppery-red Native Copper, giving the Calcite a pinkish hue. The matrix is a reddish volcanic rock over grown by colourless-white Quartz and Calcite with inclusions and free grown Native Copper, and also included by green Pumpellyite, and rare yellow micro-crystals of Epidote. A classic Michigan copper mining area specimen and comes with its own purpose made base.
