Marble is a metamorphic rock composed of recrystallized limestone or carbonate minerals, such as calcite and dolomite. When these rocks are exposed to extreme temperature and pressure, the recrystallization process forces each molecule closer together and forms an interlocking carbonate crystal structure. The hidden impurities (such as sand, silt, clay, magnesia, silica or iron oxides) in the original limestone are actually what give marble its exquisite array of colors as well as its characteristic swirls and veins.

Marble is an elegant choice for flooring, wall tiles, bathroom vanities, showers and tub decks, countertops and many more surfaces. Marble is a softer and more porous surface than granite or quartz so it can wear slightly. Part of marble’s charm is its changing luster as it ages.

Marble can range from pure white to solid black, and many types of marble are embellished with elegant veins and clouds.

Marble is quite soft and porous and does need to be sealed. The counter might come sealed from the factory, but the homeowner needs to seal it every couple of years to keep it from being stained or etched.
