Formed from the slow cooling of silica-rich magma deep beneath the Earth's crust over millions of years.
Uses & applications
Widely used in dimensional stone, construction, monuments, and interior countertops.
Geological facts
Red granite gets its signature hue from abundant potassium feldspar crystals intergrown with quartz and biotite.
