What Is Rhodochrosite?
Rhodochrosite, also known as manganese(II) carbonate, is a manganese carbonate mineral with the chemical formula MnCO3. It crystallizes in the triclinic system.
This mineral has a specific gravity of approximately 3.6 and registers between 3.5 and 4 on the Mohs hardness scale. Natural rhodochrosite often contains impurities, which can affect its coloration.
The color of rhodochrosite ranges from light pink to a deep red, influenced by the level and type of impurities present. The most prized varieties for jewelry are those with vibrant red hues. These high-quality specimens are particularly known from South American sources.
Due to its striking rose-like color, rhodochrosite is sometimes referred to as the “rose-colored stone” and commands high prices in the gemstone market.
Uses of Rhodochrosite
Rhodochrosite is primarily valued as a gemstone in jewelry, with the finest colored specimens being highly sought after. The tradition of crafting rhodochrosite into jewelry is believed to have originated near what is now Romania, which was under Hungarian rule at the time.
This historical connection may explain why Germany and Macedonia, alongside Hungary, are also noted for their rhodochrosite production. In Japan, the Ota Mine in Aomori and the Inakuraishi Mine in Hokkaido are renowned for their rhodochrosite deposits.
