Cobaltoan Calcite // 1.16 Lb.

This striking specimen features a thick coating of Cobaltoan calcite on both faces of a host rock, showcasing beautiful natural sparkle, luster, and some of the brightest magenta pigmentation seen in this mineral species. With moderately sized crystallization, the vivid pink to pinkish-purple hue is a result of cobalt ions substituting for calcium ions in the calcite’s crystal lattice. Adding further appeal, this specimen includes scattered deep green malachite crystals, creating a striking color contrast. Sourced from Zaire, this piece is a visually stunning and rare addition to any fine mineral collection.
Interesting Facts
Cobaltoan calcite’s vivid pink coloration is caused by cobalt "impurities" in the calcite's crystal structure.
Malachite, with its deep green hue, is often associated with copper-rich deposits and creates a complementary contrast with Cobaltoan calcite.
Zaire, now the Democratic Republic of Congo, is renowned for producing world-class Cobaltoan calcite specimens with exceptional color and quality.
