Serpentine or ophicarbonate stones have fragments of red, white, and green colors, although the overall hue is typically greenish. The stones polish to a high gloss, which has led to them being occasionally mislabeled as marble; however, they are fragile and unsuited for sculpture. Its color and ability to take a high polish have made serpentinites popular with many civilizations over time for decorative and ornamental work. ]]></note></mads>
