Description

• Formula: MnCO3
  Usually small crystals or granular to dense, radial-grape-formed, glass-head-like aggregates and crusts, rose-pink in
  pure condition.
  Rhodochrosite turns to dark oxide at approx. 650°C. The maximum manganese content is about 47,8%, usually
  however a part of the Mn is substituted by Fe, Mg, or Zn. Important manganese ore are in the Harz, the Carpathians, in
  the south of Spain, in western North America etc..

Similar to the rock crystal.
