A sedimentary rock formed by the precipitation of calcium carbonate from mineral springs. Predominantly white or cream in colour, the appearance of Travertine can vary depending on how it is cut. Cutting Travertine across the grain highlights the tonal variations in the deposition layers and exposes the pores (known as vein cut) while Travertine cut parallel or along the grain is presented as flowery, circular pattern (known a cross cut). It is available in various tonalities and surface finishes as well as formats. The unique patterning and texture of Travertine has been admired for thousands of years.
