Mangano Calcite with Pyrite - Peru (936g)

A 936-gram specimen of mangano calcite from Peru displaying broad, stepped rhombohedral crystal faces in soft petal pink, accented by scattered clusters of metallic pyrite. The specimen shows the classic blocky cleavage planes of calcite with visible pyrite crystals nestled into the surface texture, creating a natural contrast between the delicate pink matrix and brassy metallic highlights.

Mangano calcite develops its characteristic pink coloration when manganese ions substitute for calcium during crystal growth. The stepped crystal faces on this specimen reveal the mineral's perfect rhombohedral cleavage, a fundamental property of the calcite crystal system. The pyrite inclusions formed simultaneously in the same hydrothermal environment, creating a natural mineral association that is characteristic of Peruvian deposits.

This specimen is UV reactive — under ultraviolet light it fluoresces brilliantly, revealing hidden luminescent patterns within the pink calcite matrix.

This is a hand-sized cabinet specimen with good heft, excellent color, and well-defined crystal structure. The combination of pink calcite with metallic pyrite accents makes it a visually compelling piece for any mineral collection.
