Granite is an igneous stone that was created by the cooling of molten materials under the Earth’s surface. Granite Slabs are cut from quarried granite blocks. A key use of granite slabs is in the production of kitchen counter tops where their durability and beauty make them ideal.
Per Wikipedia, “granite is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Granites can be predominantly white, pink, or gray in color, depending on their mineralogy.”
Also, the use of this type of stone is very common in monuments. A classic and timeless example, in terms of usage as a monument, is The Vietnam Veterans Memorial in Washington, D.C.
