Rhodochrosite with Pyrite

Good American classic with rhombohedral lustrous slightly translucent crystals of rhodochrosite to 2.0 cm on edge across the front of matrix with micro pyrite crystals. Very slight micro-damage present, overall this still very good. The Emma Mine in Butte, Montana was part of the extensive Butte mining district, one of the most productive copper mining regions in the United States. Developed in the late 19th century, the mine exploited rich polymetallic hydrothermal veins hosted in granitic and volcanic rocks that contained copper minerals along with silver, gold, and other metals. Operations were carried out by underground methods and were connected to the larger network of shafts and tunnels that characterized mining in Butte. Although individual mines such as the Emma eventually closed as operations consolidated, they contributed significantly to the districts reputation as the Richest Hill on Earth.
