Physical properties

Hardness: 3 on Mohs scale; Color: Pale pink to rose; Luster: Vitreous to pearly; Crystal Structure: Trigonal/Rhombohedral; Cleavage: Perfect rhombohedral; Specific Gravity: 2.71 - 2.85.

Formation & geological history

Formed through hydrothermal processes or in sedimentary environments where manganese-rich waters interact with carbonate deposits. The pink hue is caused by the presence of manganese replacing some calcium in the crystal lattice.

Uses & applications

Primarily used as a decorative stone, in jewelry as cabochons, and as a popular specimen for crystal healing and metaphysical collections.

Geological facts

Mangano Calcite is famous for its strong fluorescence; it typically glows a bright neon pink under short-wave UV light. It is often confused with rose quartz, but its softer nature and distinct banding (when present) set it apart.

Field identification & locations

Identify by its soft pink color, rhombohedral cleavage, and low hardness (easily scratched by a copper coin). Found in Peru, Mexico, and Bulgaria. Often sold as Tumbled Mangano Calcite.
