Granite is an igneous rock that forms from the slow crystallization of magma below Earth’s surface. Granite has a distinctive grainy texture and is composed mainly of quartz and feldspar. These minerals give granite its characteristic pink, gray, or white coloration.
Granite is a very hard rock with a Mohs hardness of 6-7. This makes it difficult to carve and shape but gives it excellent durability for countertops and other applications where it sees heavy use.
Granite typically has a medium-grained to coarse-grained structure and contains large crystals that are visible to the naked eye. The most common type of granite is red granite, which gets its color from iron oxide impurities in the quartz and feldspar.
