One of the most defining characteristics of a diamond is its cut. While high grades of color, clarity, and carat weight affect a diamond, it's the cut that determines the symmetry of the stone's facets, its overall proportions, and its ability to reflect light. An expertly cut diamond will achieve high levels of brilliance, sparkle, and durability. For more information and cut types, see The Four C's.
