What is Granite? Granite is a light-colored igneous rock with grains large enough to be visible with the unaided eye. It forms from the slow crystallization of magma below Earth's surface. Granite is composed mainly of quartz and feldspar with minor amounts of mica, amphiboles, and other minerals.
Granite is a common and widely occurring type of intrusive, ingenious rock formed from Lava. Most Granite is located throughout the continental crust, usually at a depth of 1.5 km and up to 50 km. Granite has a medium to coarse texture, occasionally with some individual crystals larger than the ground mass forming the rock. This makes Granite quite rich in depth and color variation within each piece. Granites come in shades of Pink, Blue, Green and Gold to Gray, and even Black. Granite is very Hard and Tough, with an average Density of 2.75 g/cm3.
