Limestone is a sedimentary rock, traditionally found throughout the Mediterranean and Europe, formed at the bottom of the ocean, and made up wholly or mainly of calcium carbonate. In its purest form limestone is white, but it can also be colored using other materials. The calcite itself is sourced from the shells and bones of marine organisms. The sediment that builds up over many years preserves these materials into fossils. Millions of years of pressure and heat cause a chemical reaction, turning this into limestone.
Limestone is a great choice in warmer climates due to its tendency to remain quite cool, however limestone is quite a delicate variety of stone that is porous and quite susceptible to scratches, stains and fracturing, meaning limestone can damage easily when handled incorrectly.
