Excerpts from Wikipedia: Granite (June 2011)
The word granite comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a crystalline rock.
With increasing amounts of acid rain in parts of the world, granite has begun to supplant marble as a [cemetery] monument material, since it is much more durable. Polished granite is also a popular choice for kitchen countertops due to its high durability and aesthetic qualities. In building and for countertops, the term "granite" is often applied to all igneous rocks with large crystals, and not specifically to those with a granitic composition.
In some areas granite is used for gravestones and memorials. Granite is a hard stone and requires skill to carve by hand. Modern methods of carving include using computer-controlled rotary bits and sandblasting over a rubber stencil. Leaving the letters, numbers and emblems exposed on the stone, the blaster can create virtually any kind of artwork or epitaph.
