Cobaltoan Calcite // 1.84 Lb.

This striking specimen features a vivid magenta coating of Cobaltoan calcite covering both sides of its host rock, creating an exceptional display of natural beauty. The bright pink hue is caused by cobalt ions substituting for calcium ions in the calcite's crystal lattice, while deep green, velvety malachite splotches grow over the Cobaltoan calcite for a stunning visual contrast. Sourced from Zaire, where copper and cobalt mineralization coexist, this piece is a fascinating representation of geological artistry. Its natural sparkle, luster, and vivid coloration make it a standout addition to any mineral collection.
Interesting Facts
Cobaltoan calcite owes its bright magenta hue to cobalt “impurities” in the crystal lattice.
Malachite, with its deep green color, forms alongside Cobaltoan calcite in regions rich in copper and cobalt deposits.
Zaire (now the Democratic Republic of Congo) is renowned for producing high-quality mineral specimens like this, with extraordinary color and form.
