Sandstone – Sand Stone World

Sandstone is actually a sedimentary rock formed by the consolidation and compaction of sand, which is held together by a natural cement, such as silica. Natural sandstone is an extremely hard and tough material. Sandstone is typically the youngest of the quartz-based stones, with each stone having a different level of porosity, hardness and compressive strength.
