Cobaltoan Calcite // 2.44 Lb.

This exceptional specimen of Cobaltoan calcite features a thick coating on its host rock, radiating natural sparkle, luster, and one of the brightest magenta pigmentations ever seen in this species. The vibrant pink to pinkish-purple hue is a result of cobalt ions substituting for calcium ions in the calcite’s crystal lattice. With moderately sized crystallization and incredible saturation, this piece is a standout example of Cobaltoan calcite sourced from Zaire. A remarkable addition to any mineral collection, this specimen is both visually striking and scientifically fascinating.
Interesting Facts
Cobaltoan calcite’s vivid coloration is caused by cobalt "impurities," which enhance the mineral’s natural beauty.
