What is the difference between marble and granite?

A frequently question that comes up when people look for kitchen countertops or floor and wall covering is about which type of stone should be used: marble or granite? It’s common the confusion between these two terms. Although both are natural stones, each one has their own different technical features. On this article, you will see the difference between marble and granite.

The first difference is the composition of each stone. Marble is a metamorphic stone of calcareous origin and its color varies depending on the mineral present on its composition. It can be predominantly white, grayish, cream coloring with dark veins, greenish or yet predominantly black.

The term metamorphic stone is used for marble because at first it was a common calcareous, but then it went through by physical and chemical transformations due to high temperatures and pressure inside the Earth.

Granite, on the other hand, is composed by quartzite, feldspar and mica. It’s harder and stronger than marble, and there are more colors because of the distribution of its internal minerals. This composition makes granite to have a “glossy” appearance when compared to the uniform and soft appearance of the marble.

Since granite is harder than marble, it’s also more resistant. These characteristics make granite the most used in kitchen countertops or laundry rooms, because in the past it was better known for being more resistant to scratches and stains caused by using sharp knives or liquid spills. However, nowadays the stone market has specific products that, when used properly, allow the use of marble in wet areas like kitchens and bathrooms, ensuring more resistance against scratches, absorption of liquids and corrosions.

Both marble and granite cleaning is easy and simple. Just use a wet cloth with neutral detergent when necessary.


For projects with marble, it’s recommended to seal it up once or twice a year. In the case of granite, it can be done about once every two years. However, the maintenance period may vary according to the use. It’s always important to follow the manufacturer’s recommendations for a better use of the product.
