ARAGONITE (Calcium Carbonate)

Aragonite is a polymorph of calcite, which means that it has the same chemistry as calcite but it has a different structure, and more importantly, different symmetry and crystal shapes. Aragonite's more compact structure is composed of triangular carbonate ion groups ( CO 3 ), with a carbon at the center of the triangle and the three oxygens at each corner.

Coral - Wikipedia

Coral skeletons are biocomposites (mineral + organics) of calcium carbonate, in the form of calcite or aragonite. In scleractinian corals, "centers of calcification" and fibers are clearly distinct structures differing with respect to both morphology and chemical compositions of the crystalline units.

Calcite Value, Price, and Jewelry Information ...

Calcite is common and abundant throughout the world. The material has little intrinsic value since it is not scarce.
