Diamond cut is one of the most crucial elements to consider when selecting a diamond. The cut refers not to the shape of a diamond, but the balance of proportion, symmetry, and polish achieved by the diamond cutter. The extent of how well the diamond is cut is directly correlated to the diamond’s overall beauty. The better a diamond has been cut, the greater the diamond’s ability to reflect and refract light. Modern diamond cutters understand how light moves through diamonds and have established a set of specific proportions and angles to best optimize the diamond's inner brilliance.
