For a classic, ageless look, builders have been turning to these materials for centuries. Marble can also be used to describe any stone that can take a polish (not including granite) such as travertine, onyx, serpentine, and limestone. Each type of stone has distinct veining characteristics and can be polished, giving them a unique, natural beauty. Unlike granite, these materials are softer and more porous, and require proper care. Marble is not recommended for countertops.
