2.9" Sparkling Cobaltoan Calcite Crystal Cluster - D.R. Congo
This is a sparkling, cobaltoan (cobalt-bearing) calcite crystal cluster with small spots of malachite, collected from the Kakanda deposit in the Democratic Republic of the Congo.
Cobaltoan calcite, also known as cobaltocalcite, is one of many different varieties of calcite, forming with a chemical composition of (Ca,Co)CO3. It crystallizes in a trigonal crystal system and forms rhombohedral or scalenohedral crystals. These crystals tend to display a pink color of which intensity can range anywhere from a pinkish-salmon to a hot pink.
