Material: Granite

Granite is a common and widely occurring type of intrusive, felsic, igneous rock. Granite has a medium to coarse texture, occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry.

Granites can be pink to dark gray or even black, depending on their chemistry and mineralogy.

Granite is nearly always massive (lacking internal structures), hard and tough, and therefore it has gained widespread use as a construction stone. The word granite comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a crystalline rock.
