2.85" Polished Cobaltoan Calcite Sphere - Congo

This is a beautiful, hand-polished sphere of pink cobaltoan calcite from the Congo. The lapidary work is very nice, and allows for the vivid coloration of the cobaltocalcite to be easily seen, as well as very small traces of shinning, natural copper within and on the exterior of the sphere. 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.
