Anotations

Scope note:

Metamorphic rock containing of serpentine (magnesium silicate) and calcite (calcium carbonate) cemented together with red iron oxide (ferrous oxide). 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.
