Rhodochrosite is a mineral belonging to the calcite group. The name of the mineral derives from the Greek ρόδον (pink) and from χρώσις (color) and refers to the often pink color of this mineral. In America it is known as "rose of the Incas", as the rocks in which it is found were particularly exploited by the Incas in the 13th century AD to extract silver and copper.
