• Crystal system : trigonal.

• Color : bright pink to magenta, due to the presence of cobalt (Co).

• Hardness (Mohs scale) : 3 (relatively soft).

• Luster : Vitreous.

• Transparency : translucent to opaque.

📍 Origin and deposits

Cobaltocalcite is found mainly in cobalt and copper deposits, often associated with other minerals such as malachite, dolomite or sphalerite.

• Main deposits :

  • Katanga (Democratic Republic of Congo) – one of the most famous for its spectacular specimens.
