2.3" Cobaltoan Dolomite Crystal Cluster - Kakanda, Congo
This is a cluster of vibrant pink cobaltoan dolomite crystals that was collected from the Kakanda deposit of the Democratic Republic of the Congo. Similar to cobaltoan calcite, cobaltoan dolomite gains its pink coloration from cobalt ions replacing magnesium and/or calcium within the crystal lattice.
About Cobaltoan Dolomite
Cobaltoan dolomite is a vibrant, pink to purplish-pink variety of the mineral dolomite that owes its striking coloration to traces of cobalt. This rare and visually distinctive mineral is typically found as crystalline coatings or rhombohedral crystals on matrix, often associated with cobalt-bearing minerals such as erythrite. The vivid hue and lustrous crystal surfaces make cobaltoan dolomite a favorite among mineral collectors. It is most famously sourced from the Katanga region in the Democratic Republic of the Congo, where some of the world’s finest specimens have been found. Though chemically similar to regular dolomite (CaMg(CO₃)₂), the substitution of cobalt in place of magnesium during formation gives it its unmistakable color.
