Gray Granite is an igneous rock formed from the slow crystallization of magma beneath the Earth's surface. It is primarily composed of quartz, feldspar, and mica, which give it its distinctive appearance and color variations. The gray hue in granite results from the presence of minerals like biotite and hornblende. The formation process of gray granite takes millions of years, during which the minerals meld together under intense heat and pressure, creating a stone that is both incredibly hard and visually stunning.
