It is formed from hot molten magma its colour can be dark or light grey brown or even pink according to the proportions of its minerals. Granite is a strong stone because its mineral grains have grown tightly together during a very slow cooling period. Color variation is a response to the percent of each mineral found in the sample. The crystals in granite provide a variety of mixed colors feldspar pink or red mica dark brown or black quartz clear pink white or black and amphibole black.

Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals this mineral composition usually gives granite a red pink gray or white color with dark mineral.
