An ornamental rock composed of Calcium carbonate in the form of calcite. Limestone onyx is obtained from stalactite and stalagmite formations frequently found in caves. Calcium carbonate is deposited in icicle-shaped masses from drops of mineral laden water. Although usually pure white in color, trace amounts of other minerals may add yellow, pink or green colors to the stone. Limestone onyx received its name because it exhibits either stripes or concentric circles when it is cut. Thin sheets of limestone alabaster are translucent and were used in ancient times for window panes.
