The choice between marble and granite depends on the aesthetic effects you want to achieve and how much use or abuse the stone will be subjected to. Although both are natural stones and quarried from the earth, granite and marble (and marble's relatives - limestone, onyx and travertine) are very different from each other. The greatest difference between granite and marbles lies in their porosity, softness and durability.
Marble :
Marble is a metamorphic rock formed when a carbonate rock is exposed to high temperatures and intense pressure. The heat and pressure cause the re-crystallization of the original carbonate mineral grains, which forms a denser rock. The characteristic swirls and veins found in marble are usually due to the various mineral impurities (clay, sand, silt, iron oxides), which were originally present as grains or layers in the limestone.
This stone is among the most elegant and luxurious of stones. Marble's beauty will last for generations and is versatile enough for use throughout the home in such places as fireplace surrounds, ornamental furnishings, walls, flooring, and bathrooms. Marble especially stands out in the bath. It can be applied on almost every surface, including vanities, shower walls, tub decks and flooring.
Given that marble is more susceptible to staining by many foods, spilled liquids and other household materials, we do not recommend their use for kitchen countertops. Softer and more porous than granite, marble is more suitable for less-trafficked, formal areas.
Granite :
Born from molten magma, granite is a much more durable and functional stone than marble. Granite's crystalline structure is far more resistant to abrasions, staining and discoloration than most marbles. Denser and stronger than all natural stones, granite is an excellent choice for high traffic areas where class and style is desired.
Granite feels at home in a country farm house as well as a modern high rise. This remarkable stone is ideal for kitchen countertops, accent islands, bar tops, dining tables, flooring- the options are endless!
