The definition of “granite” varies. 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. By this classification, rocks such as anorthosite, gneiss, granite, granodiorite, monzonite, syenite, gabbro and others are all sold under the trade name of “granite”.
Granite is an important structural and decorative stone. It's used for immense structural work due to its high compressive strength and durability. It is the hardest structural stone. Granite's rich colors, stiffness and density, make it an ideal choice for flooring, counter tops, vanities as well as exterior applications. Many stylish patterns and colors make granite the most versatile and trendy of all stones. It is also a very low-maintenance stone. Granite is composed of quartz, feldspars, micas and other minerals. These minerals contribute to the color and texture of the granite stones. Granites get their wonderful variety of colors and patterns from minerals that are melted into the liquid mass as it is formed.
