What is the difference between limestone, marble and granite?
Limestone and marble show subtle veining and movement. They are sedimentary rocks composed primarily of calcium carbonate and are sensitive to acids. “Marble” derives from the Latin “marmor,” which means “to shine,” so marbles are hard limestones that accept a polish well. Limestone and marble are often selected for the master bath but many also perform well on high-traffic floors when a honed finish is specified. Granites are harder rocks of volcanic origin and are not acid-sensitive. Frequently they display artistic veining and movement. Granites are generally selected for kitchen counters and high-traffic floors where performance is the priority and a polished finish is desired.
