2.4" Polished Cobaltoan Calcite Slab - Congo
While most slabs will maintain a consistent thickness, this slab varies in thickness, from .1" to .35" thick.
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.
