Cobalto calcite is a vibrant pink cobalt rich variety of the mineral calcite. The pink colour is a result of a chemical substitution where cobalt replaces calcium within the crystal lattice.
The mineral class is carbonate and the crystal system is trigonal l.
Hardness is 3 on the Mohs scale.
Cobalto calcite typically forms in low temperature hydrothermal environments.
It is found in the oxidized zones of cobalt bearing ore deposits.
It crystallizes from mineral rich fluids seeping through cracks and cavities,depositing on a matrix of iron oxides.
