Rhodochrosite is a manganese carbonate mineral that ranges in color from light pink to bright red. It is found in a small number of locations worldwide where other manganese minerals are usually present. Specimens with a wonderful pink color are used to produce highly desirable gemstones. Rhodochrosite is rarely found as well-formed crystals that can be extremely valuable as mineral specimens. Chemical Composition: MnCO3; Hardness: 3.5 - 4; Color: Bright red, hot pink, light pink, orange-red, brown, gray; may also be banded light and dark pink. Rhodochrosite is one of the prettiest and desirable of all minerals. Its deep red and hot pink crystals are extremely sought after and good crystals command extremely high prices. When Rhodochrosite is exposed to the atmosphere, it may develop a thin film of manganese oxide on its surface. This may slightly darken the color of a specimen. Rhodochrosite sometimes alters into black manganese oxides, and black manganese oxide stains are usually associated with Rhodochrosite.
