Sweet Home Mine Famous for Rhodochrosite
The Sweet Home mine which is famous for its world class specimens of the mineral rhodochrosite is in the mining town of Alma, Colorado, USA. After its discovery in 1873 small amounts of silver were mined there from the 1870's until the 1960's. Rhodochrosite was at that time just a gangue mineral which is the worthless material that surrounds or is mixed in with a valuable mineral.
Rhodochrosite went on to make the Sweet Home mine famous around the world and some of the finest specimens ever to have been mined have come from there.
