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 plutonic or deep seated rock which contains minerals of quartz, feldspar, and mica. It is the presence of these three elements that give granite its beauty and warm, rich colors. The rock itself is wholly crystallized and features unique granular patterns.
