Manganocalcite
Manganocalcite, also known as manganoan calcite, is a manganese-rich variety of calcite with the formula (Ca,Mn)CO3, prized by collectors for its soft pink to vivid rose-red color. The hue comes from manganese (Mn2+) substituting for calcium within the trigonal lattice, and the mineral forms part of a solid solution series linking calcite to rhodochrosite — with which it is frequently confused, though true manganocalcite typically shows paler, more pastel tones. It crystallizes in rhombohedral or scalenohedral forms, sometimes as banded masses, botryoidal crusts, or the distinctive spiky, radiating crystal sprays sought after by specimen collectors.
