Travertine is a type of limestone that has been deposited by a mineral spring, which is what’s responsible for its smooth finish and coloring. Travertine is a 100% natural rock formation and is not manufactured from a composite mixture. Travertine comes in a variety of colors and shades – in fact, just about every travertine tile or paver features coloring that is slightly unique. This is because it is a sedimentary stone, which means that it absorbs coloring from nearby minerals, such as iron ore. When iron deposits are located near travertine deposits, the iron oxide deposits its coloring into the travertine, causing these slight and often stunning variations. Travertine is used for a range of purposes including interior and exterior floor tiles and wall cladding for floors, bathrooms and vessels.
