Calcite Mangano Rough Stone - per kilo

Manganoan calcite or manganocalcite is a variety of calcite rich in manganese, which gives the mineral a pink colour. Its chemical composition is (Ca,Mn)CO3. It was first reported from the Banská Štiavnica Mining District, Slovak Republic, but is widely distributed around the world, notably in the Cave of Swords at Naica, Chihuahua, Mexico, and in Bulgaria. Manganoan calcite is sometimes confused with rhodochrosite. The amount of manganese in manganocalcite varies at different localities, and the mineral forms a solid solution series between calcite and rhodochrosite, with the colour becoming redder with a higher proportion of manganese. This Mangano Calcite is from Balichistan Pakistan
