Description

Rhodochrosite

A rose red mineral composed of Manganese carbonate. Rhodochrosite is mined in Rumania (Kapnik), Germany (Saxony, Westphalia), England (Cornwall) as well as in the U.S. (New Jersey, Connecticut, Colorado, Montana, and Nevada). The transparent to opaque mineral ranges in color from pink to deep red. It has been used as a minor ornamental stone and as a source for Manganese.
