A cut grade is the measure of a diamond's light performance. Cut with proper proportions, light is returned out of the top of the diamond. If it is cut too shallow, light leaks out of the bottom; too deep and it escapes out of the side.
We recommend considering carat weight along with two other influential characteristics: the overall dimensions and the cut grade of the diamond.
Learn MoreG color: The highest "near-colorless" grade. Color may be detectable when compared to much higher "colorless" grades. Excellent value.
