Granite is a light colored igneous rock with grains large enough to be visible to the unaided eye.  It forms from the slow crystallization of magma below the Earth's surface.  Granite is composed mainly of quartz and feldspar with small amounts of mica, amphiboles, and other minerals.  This mineral composition usually gives granite it's unique colors.  In our Ruby Granite, you can find deep reds along with glimmers of dark tones such as blues and greens. A remarkable stone indeed.
