The “C” with the most impact on the value and brilliance of your diamond is CUT
People often think that a diamond’s “cut” is referring to its shape (round, princess, oval, marquise, pear), but a diamond’s cut grade is actually a measurement of how well the diamond reflects light. The better the cut grade, the more brilliant and sparkly your diamond will be. It takes incredible skill to fashion a diamond with precise symmetry, polish, and proportions, which gives the diamond a brilliance unmatched by any other gemstone.
