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. This mineral composition usually gives granite a red, pink, gray, or white color with dark mineral grains visible throughout the rock. Granite is an important structural and decorative low-maintenance stone that retains its beauty throughout the years & it is said to be the most resistant to Bacteria, Granite contains essential minerals: feldspar, quartz, silica and mica. These minerals are present in different proportions, giving each form of Granite its own color, texture and structural characteristic.
