Granite is a type of igneous rock that is formed by the cooling and solidification of magma or lava deep below the Earth’s surface. It is composed of minerals such as feldspar, quartz and mica, which give it its characteristic spotted appearance.

It is a material known for its hardness and wear resistance, which make it popular for construction. It is commonly used as a building material for countertops, floors, walls and monuments, and is available in a variety of colors and patterns, ranging from light shades of white and gray to darker shades of black, brown and red.

However, it is important to note that granite is a porous material and can absorb liquids, which can cause stains if not properly sealed and maintained.
