Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). It is commonly composed of tiny fossils, shell fragments and other fossilized debris. Limestone is usually gray, but it may also be white, yellow or brown. It is a soft rock and is easily scratched.
White calcite is a crystal of calcite that originated in ancient times. It's found in many areas, including limestone deposits and calcite collections around the world. The calcite group includes minerals from the class carbonates, which form when calcium ions interact with carbonate molecules.
