Cut

Diamond cutting techniques have been refined since the fifteenth century. Today, the finest diamond cutting still occurs in the hands of a skilled craftsman.

The cut of a diamond is the most important factor to consider because the cut determines the fire and the brilliance of the diamond. If the diamond is cut with just the right proportions and at certain precise angles, the stone's ability to reflect and refract light will be maximized. When a diamond is cut to appropriate proportions, light will bounce freely within the diamond and reflect back out of the crown without escaping through the opposite side or the bottom of the stone.
