Limestone

Sedimentary rock consisting of calcite composed mostly from marine organisms.
Over time, the shells, skeletons and calcium are mixed with algae, sponges and the remains of other sea life to form hard layers of the rock we know as limestone.

Core Characteristics

Mostly beige/greyish colors that are never completely solid. Although the material that forms this stone may be similar to marble, the final product or look is less polished or glass-like and is often compared to the faded features of travertine, also composed of similar material.

A Class of Its Own

Limestone is the one-of-a-kind stone that has some of the world’s oldest fossils still buried inside the rock for eternity.

Most Select Setting

Facing stone, floor tiles, stair treads, window sills and fireplaces.
