A variety of Calcite

Travertine is formed by calcium carbonate dissolving in ground water and then being deposited on the earth’s surface by rivers, natural springs, or geysers. Often it is banded or layered and in pastel shades of almost any colour. Sold as "Mexican Onyx" in carvings of chess men etc. Although referred to as "Onyx" in commercial trade, it has the hardness of calcite that is much softer than real Onyx which is a black and white banded agate.
