4" Botryoidal Rhodochrosite Formation - Argentina

This is a partially polished rhodochrosite stalactite segment, collected from the Capillitas Mine in Argentina. Some of the botryoidal formations have been polished down, displaying the beautifully defined banded formation. The portion of this mine that produced these types of banded rhodochrosite specimens, was mined out decades ago.

Rhodochrosite is a manganese carbonate mineral with the chemical composition MnCO3. The crystals typically have a rosy pink to red coloration with rhombohedral cleaving in three directions. It forms from hydrothermal pockets and can be found as both crystals and in banded formations. Its color and occasional banding patterns make it a popular stone for faceting and cutting into cabochons. Premier specimens come from China, South Africa, Argentina, where it is the national mineral, and from the Sweet Home Mine in Alma, Colorado.
