2.1" Polished Cobaltoan Calcite Sphere - Congo

This is a beautiful, hand-polished sphere of pink cobaltoan calcite from the Congo. The lapidary work is nice, and allows for the vivid coloration of the cobaltocalcite to be easily seen. It makes for a very aesthetic display piece. Comes with the pictured display stand.

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 it 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.
