Greenwich is a bold and eye-catching dark castle rock style thin stone veneer.  The stone falls loosely into the castle rock style due to the rectangular shapes, however, the individual pieces are smaller than our other castle rock offerings.  Greenwich is a natural sandstone showcasing variation only seen in natural stone.  The stone appears dark grey from a distance but upon close inspection streaks of white and tan are visible.  Greenwich also has a great deal of texture variation ranging from smooth to pimpled or rippled. Between the color and texture variations, the stone provides a sense of movement.
