About Rhodochrosite
MnCO₃
The rose-red manganese carbonate, softer than rhodonite and forming a complete solid-solution series with siderite. It is prized as crystals and as banded ornamental material.

- Cleavage / fracture
- Cleavage perfect on {10-11} (three directions); parting on {10-12}; fracture conchoidal; brittle
- Magnetism / fluorescence
- Reported as non-fluorescent
Crystallography
- Crystal system
- Trigonal
- Space group
- R-3c
- Structure
- Calcite-type carbonate; hexagonal-setting cell a = 4.777 Å, c = 15.670 Å.
- Typical habit
- Rhombohedral and scalenohedral crystals; also bladed, columnar, stalactitic, botryoidal, granular or massive
- Twinning
- On {10-12}, as contact and lamellar twins
- Optical data
- Uniaxial (-); omega = 1.814-1.816, epsilon = 1.596-1.598; birefringence about 0.218; weak pleochroism
Formation and use
- Formation
- Hydrothermal vein mineral in low-temperature ore deposits and a product of the oxidation of manganese ore.
- Uses
- Manganese ore for steel and aluminium alloys; banded material is used as ornamental stone and in jewelry, while faceting is rare because of softness and cleavage.
- Stability and care
- Soft with perfect cleavage, so specimens and cut stones are easily damaged and need gentle handling.
