Sandstone is a sedimentary rock composed of sand-sized grains of mineral, rock or organic material. It also contains a cementing material that binds the sand grains together and may contain a matrix of silt- or clay-size particles that occupy the spaces between the sand grains.
As a landscaping and building stone, sandstone is full of character, with warm colors. It can also be quite durable. The majority of sandstone is used as flagstones, ornamental rocks for buildings, monuments, grave stones, bookends, beverage coasters, tiles and many other possible uses.
