The Detroit City Portal mining operations began in 2017. After 7 years of mining operations, the Detroit City Portal of the Sweet Home Mine was permanently closed in September 2024. This mine was approximately 300 feet, or 90 meters, above the old Sweet Home Mine workings that it was closed in 2004. The portal was removed and the entrance was cemented and reclaimed. The two mines did not connect but both of them have produced some of the highest-quality Rhodochrosite specimens in the world. This specimen is a very good example of the good quality of the specimens found there, it is formed by a very well formed rhombohedral crystal of Rhodochrosite with sharp faces and edges, with nice red color and high brilliance. Settled on a bed of small crystals of Quartz. A classic in perfect condition, no damage.
