Colorado's Sweet Home Mine Yields Rare Rhodochrosite Gems
Nestled in Colorado's historic Alma District, the Sweet Home Mine initially made its mark as a silver mine in 1873 [3]. However, its fame reached international heights not for its silver, but for the exceptional quality of its rhodochrosite, a distinctive mineral known for its vibrant red to pink color and well-formed rhombohedral crystal shapes.
The Alma district, home to the Sweet Home Mine, has a rich mining history, with gold mining dating back to 1861 following the discovery of gold in one of the headwater creeks of the South Platte river [2]. The Sweet Home Mine, however, would become renowned for its precious rhodochrosite crystals, which are highly sought after by collectors and museums for their intense color and crystal form.
The Sweet Home Mine's rhodochrosite specimens are iconic in American mineralogy and have become a cornerstone of the country's mining history. The vibrant red and pink hues, highly symmetric rhombohedral shapes, and unique formation conditions are believed to have contributed to the rarity and quality of the specimens.
The mine's rhodochrosite is particularly prized due to its purity. With less than 1% atomic Fe+Mg+Ca contamination, Sweet Home Mine rhodochrosite is considered the purest in the world [4]. Unfortunately, an incredible rhodochrosite-rich pocket discovered in 1966 was stolen by a miner before it could be properly exploited [5].
The Sweet Home Mine's transformation from a silver mine to a premier source of fine rhodochrosite cemented its legendary status in both mining and mineralogical circles. Today, the mine's reclaimed by nature, with a building acting as the lone monument to its rich history. The Sweet Home Mine's rhodochrosite specimens remain among the most sought-after worldwide, celebrated for their beauty and rarity in the world of mineral collecting.
