Granite is a hard, durable, and coarse-grained igneous rock composed mainly of quartz, feldspar, and mica. It forms from the slow cooling of magma deep beneath the Earth's surface, giving it a visibly speckled appearance and a crystalline texture. Known for its strength, resistance to heat and scratches, and wide range of colors, granite is commonly used in construction, countertops, flooring, and monuments. Its natural beauty and long-lasting qualities make it a popular choice for both interior and exterior applications.
