Limestone

Limestone is a naturally occurring sedimentary rock, forming primarily in shallow marine environments from calcium carbonate crystals over hundreds of millions of years. Due to its prevalence and relatively low density, it has seen use in art and architecture in almost every corner of the Earth. From the Pyramids of Giza to the Empire State Building, limestone is found literally everywhere.

In homebuilding, limestone has long been a popular material choice, particularly for floor tiling or fireplace fixtures. Due to the specifics of its formation, it does not come in a wide variety of colors, but if you’re content to pick from gray, cream, and tan, you won’t go wrong choosing limestone.
