The Essentials You Need To Know When Purchasing and Caring For Your Diamond.
Diamond Cut

Polish

Polish, along with Symmetry, determines the overall craftsmanship of the diamond, indicating the care and attention to detail by the cutter. Polish is defined as quality and smoothness of the diamond's surface. The polish is evaluated by a skilled grader under 10X magnification. There are a number of factors that can detract from the diamond's overall polish:

Once the diamond has been carefully reviewed face-up and from the side, a grade is assigned. GIA assigns one of five grades (Excellent, Very Good, Good, Fair, Poor) based on the graders overall impressions, while AGSL uses a ten point scale with 0 being the best and 10 the worst.

Although polishing factors do not have as much impact as the proportions on the brilliance, fire and scintillation of the diamond, it is important to have the best polish possible to maximize the diamonds full potential.
