‘Cut’ - refers to the visible shape of a diamond (pear, emerald, square, and round). Cut is also about how the angles and facets sparkle off each other, the symmetry of the cut and the polish of the surface. The cut determines the value of your diamond, because in a well-cut stone the brilliance and beauty of diamond is fully achieved. Round diamonds tend to be the most brilliant, followed by square cuts. To cut a long story short, the more light a diamond reflects, the better the cut.
