Also available in lots, at this link.

Variety of Calcite (Calcium Carbonate) which contains pinkish Manganese cations in solid solution (CaMn) 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 as well as in Bulgaria.
Manganoan calcite is sometimes confused with rhodochrosite. The amount of manganese in manganoan calcite varies at different localities, and the mineral forms a solid solution series between calcite and rhodochrosite, with the color becoming redder with a higher proportion of manganese.
