It may be used for memorials, headstones, facades, and other constructions. The name derives from Middle English flagge meaning turf, perhaps from Old Norse flaga meaning slab or chip Hardscape Illinois August 14, 2013 2 Illinois Landscape Contractors Association (ILCA) 1 3/20/2017 Flagstone is a sedimentary rock that is split into layers along bedding planes. The material that binds flagstone is usually composed of silica, calcite, or iron oxide. The rock color usually comes from these cementing materials. Typical flagstone colors are red, brown, blue, and buff, though exotic colors exist.
