Travertine interlocking pavers are very popular in most highend Naples homes. The large pallet of colors and textures can complement most any home exterior. If properly sealed and cared for, this stone will last generations. Travertine is a form of limestone deposited by mineral springs, especially hot springs. Travertine pavers often has a fibrous or concentric appearance and exists in white, tan, cream-colored, and even rusty varieties. It is formed by a process of rapid precipitation of calcium carbonate, often at the mouth of a hot spring or in a limestone cave. In the latter, it can form stalactites, stalagmites, and other speleothems. It is frequently used in Italy and elsewhere as a building material.
Travertine is a terrestrial sedimentary rock, formed by the precipitation of carbonate minerals from solution in ground and surface waters, and/or geothermally heated hot-springs. Similar (but softer and extremely porous) deposits formed from ambient-temperature water are known as tufa.
