Travertine is a sedimentary rock that is often found in hot and cold groundwater springs. It is also found in caves made of limestone. In fact, travertine is a type of limestone that is due to the water outflow cycle of calcite and aragonite. Travertine is a type of limestone that has a high percentage of porosity. Given that the structure is layered and formed over time, it is natural that the material of each layer is different from each other. This issue has caused this type of stone to be wavy. Travertine stone has a great variety in terms of material, quality and color, and some of them have several varieties.
