Limestone

Limestone is a sedimentary rock composed largely of the mineral calcite. Limestone is less resistant than most igneous rocks, but more resistant than most other sedimentary rocks. Limestone is readily available and relatively easy to cut into blocks or more elaborate carving. It is also long-lasting and stands up well to exposure.
