Granite is a coarse-grained igneous rock composed mainly of quartz, feldspar, and mica minerals. It is formed deep within the Earth's crust through the slow cooling and solidification of molten magma over millions of years. The distinctive feature of granite is its interlocking grain structure, where the individual mineral grains are tightly bound together, giving the rock its characteristic durability and strength.

Granite typically exhibits a speckled appearance, with a wide range of colors including shades of gray, pink, white, and black. The exact composition and coloration of granite can vary depending on the specific minerals present and their proportions. The presence of feldspar minerals gives granite its overall light color, while the dark-colored minerals such as biotite and hornblende contribute to its speckled or mottled patterns.
