Cut is the most influential factor in a diamond's beauty. It determines how effectively a stone returns light to the eye, which is what creates brilliance, fire and sparkle. Cut refers to the precision of a diamond's facets, the symmetry of their alignment and the proportions that govern how light travels through the stone.
A well cut diamond will appear lively and bright, while a poorly cut diamond can look dull even if its colour or clarity grades are high. Round brilliant diamonds receive a formal cut grade from laboratories, and we select only those with excellent ratings for superior performance.
Fancy shapes do not receive a standardised cut grade, so we evaluate each stone based on the quality of its polish and symmetry, as well as the visual balance of its proportions. Only stones that meet our internal standards for light performance and craftsmanship are chosen.
