Peach mangano calcite ( Bulgaria )

Peach Mangano Calcite – Bulgaria

Educational / Geological Overview

Mangano Calcite (CaCO₃) is a manganese-rich variety of calcite, giving it its distinctive soft peach to pink coloration. This specimen originates from Bulgaria, a region known for producing high-quality calcite crystals with exceptional clarity and color.

• Crystal System: Trigonal

• Hardness: 3 (Mohs)

• Luster: Vitreous to pearly

• Transparency: Transparent to translucent

• Formation: Typically forms in hydrothermal veins, cavities, and sedimentary deposits, often associated with other carbonate and sulfide minerals.

Peach Mangano Calcite is prized by collectors for:

• Its gentle pastel coloration, which is rare among calcites.

• Well-formed rhombohedral or scalenohedral crystals, often on matrix.

• Smooth, tactile surfaces ideal for display or handling.

Geological Significance:

• Manganese impurities replace calcium in the calcite structure, producing the characteristic peach or pink hue.

• The Bulgarian deposits reflect low-temperature hydrothermal and secondary mineralization processes, producing high-purity, visually striking specimens
