Travertine is a type of natural stone formed from mineral deposits, primarily calcium carbonate, that accumulate around hot springs and limestone caves. It is characterized by its porous texture and unique patterns, which can vary in color from white to tan, and even reddish hues. This stone is often used in construction and landscaping due to its durability and aesthetic appeal. Commonly found in regions like Italy and Turkey, travertine has been used since ancient times, notably in the construction of famous structures such as the Colosseum in Rome. It is popular for flooring, countertops, and outdoor patios, providing a classic and elegant look to various spaces.
