Physical properties

Hardness: 3 on Mohs scale; Color: Pale pink to white; Luster: Vitreous to pearly; Crystal structure: Trigonal/Rhombohedral; Cleavage: Perfect rhombohedral; Specific Gravity: 2.71

Formation & geological history

Formed in sedimentary environments, hydrothermal veins, or as a secondary mineral in igneous rocks via precipitation of calcium-rich solutions. Often found in deposits dating from various geological eras where limestone undergoes alteration.

Uses & applications

Used primarily in lapidary arts for carvings (like the butterfly wings shown), jewelry (cabochons), and as a popular specimen for metaphysical collectors due to its soothing appearance.

Geological facts

Mangano Calcite is often fluorescent under UV light, glowing a bright neon pink. It gets its distinctive color from the presence of manganese within the crystal lattice.

Field identification & locations

Identify in the field by its rhombohedral cleavage, softness (can be scratched by a copper coin), and strong effervescence when exposed to dilute hydrochloric acid. It is commonly found in Peru, Mexico, and Bulgaria.
