What is a granite stone

A geologist might define granite as a coarse-grained, quartz- and feldspar-bearing igneous rock that is made up entirely of crystals. However, in the dimension stone trade, the word “granite” is used for any feldspar-bearing rock with interlocking crystals that are large enough to be seen with the unaided eye

Granite  is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Granites is white, black,pink, or gray in color. The word “granite” comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a holocrystalline rock. Strictly speaking, granite is an igneous rock with between 20% and 60% quartz by volume, and at least 35% of the total feldspar consisting of alkali feldspar

Granite is nearly lacking any internal structureshard, and tough. These properties have made granite a widespread construction stone throughout human history
