Pink manganocalcite — a manganese-rich variety of calcite — produces some of the most delicately beautiful mineral specimens in the carbonate family. Our collection features specimens with the soft rose-pink coloring, rhombohedral crystal forms, and occasional fluorescence that make manganocalcite a collector favorite for both its aesthetics and its mineralogical interest.
The pink color in manganocalcite comes from manganese (Mn²⁺) substituting for calcium in the calcite crystal structure. The intensity of the pink varies with manganese concentration — from barely perceptible blush to vivid rose. Many manganocalcite specimens fluoresce brilliantly under ultraviolet light, adding another dimension of visual interest. The mineral forms in hydrothermal veins, metamorphic environments, and manganese-rich sedimentary deposits.
Hubei Province in China has become a premier source of collector-quality pink manganocalcite, producing specimens with excellent crystal development and rich color. Peruvian deposits also yield fine material with distinctive crystal habits. At Mohs 3, manganocalcite is soft and acid-sensitive — display it in a protected case and never clean with household chemicals. Explore our pink manganocalcite mineral specimens for the gentle beauty of manganese-tinted carbonate crystals.
