1.15" Botryoidal Rhodochrosite Formation - Santa Eulalia, Mexico

Botryoidal Rhodochrosite Formation - Santa Eulalia, Mexico #253335

This is a unique aggregation of pale, salmon-pink rhodochrosite crystals packed together in botryoidal formations on a quartz and hematite matrix. It was collected from Potosi Mine in the Santa Eulalia mining district of Chihuahua, Mexico. The specimen measures 1.15" wide.

This specimen has been mounted with mineral tack for museum-quality display.

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.
