There are several things that can actually cause your diamond to appear dull. Hair spray, makeup, just every day wear and tear. The substances that get attached to that diamond through every day wear and tear can make it look dull. The wonderful thing about diamonds is that they never ever lose their beauty and brilliance once they're cut. You simply have to clean that diamond and you get that look that you had the day you bought it.
