Rhodochrosite is one of the most premier collector minerals of all time, and nowhere as produced more rhodochrosite than Argentina. The banded pink mineral usually grows in stalagtites which is unique to this locality. These spheres have been cut and polished from those stalagtites, and that is why the banding is so prominent. Rhodochrosite is a rare mineral, highly prized and we are happy to feature these hand picked mini spheres to represent the species. Production at the mines is slowing down, and it may be soon that rhodochrosite from Argentina is a thing of the past.
