2.7" Rhodochrosite Stalactite Segment - Argentina

Rhodochrosite Stalactite Segment - Argentina #65050

This is a partially polished rhodochrosite stalactite segment, collected from the Capillitas Mine in Argentina. The banding of this specimen is beautifully defined and contains wonderful coloring. 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.
