The Difference Between Marble and Granite - Granite Guy Inc.

It can be tough to choose between two beautiful natural stones such as marble and granite. But choose you must! Each one is no-doubt visually appealing and will enhance any kitchen or bath. But they each have their own attributes that make them unique. Let’s delve more into what sets them apart.

In short, marble has veining throughout, whereas granite features a more fleck-like, granular appearance. Natural stone, based on composition, falls into two general categories:

• Siliceous stone: Comprised mainly of silica, or quartz-like particles, these stones are very durable and easy to clean. These stones include granite, slate and sandstone.  
• Calcareous stone: Comprised mainly of calcium carbonate, these stones are sensitive to acids, including cleaning products, citrus fruits, vinegar, wine and tomatoes. As such, they require different cleaning procedures and products than siliceous stone. These stones include marble, travertine, limestone, and onyx.

The one you choose will depend on the look you’re going for and how much maintenance you want to do.

Differences

Both marble and granite are natural and quarried from the earth, but they have many different properties. The biggest difference lies in their porosity. Marble is softer and more porous than granite. Granite, on the other hand, has a crystalline structure that makes it more resistant to abrasions, stains, and discolorations. It’s actually the strongest of all natural stones.

Granite is an igneous rock, meaning it was once molten and formed as it cooled within the earth’s crust.

Marble, conversely, was once limestone that changed under intense heat and pressure, to alter its crystalline structure and introduce other minerals. These other materials are what contribute to marble’s distinctive veining.

Similarities

There are also many similarities between the two.

• Both materials are hard, heavy, heat and scorch proof, and are available in a variety of colors and patterns.
• Both are created in nature, bringing many natural variations in colors and patterns.
• Both stones can be stained by intensely-colored foods, acidic or oily foods. This means you have to seal them regularly, usually just once a year.
• Both are created through complex reactions in the earth, often taking millions of years to form. This is why it’s so hard to mimic their appearance with man-made material.
• Both make beautiful countertops, backsplashes, wall coverings and floor coverings.
• Both are unique stones that offer a high return on investment for any kitchen or bath project.
