This is a sparkling, cobaltoan (cobalt-bearing) calcite crystal cluster 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.
