The allure of a diamond is affected more by cut than any other attribute. This is because the cut of a diamond affects the fire, sparkle and brilliance—in essence, it provides the ‘wow factor’ of a diamond! The standard diamond shape is round brilliant, but other shapes, such as heart and oval, are included in the category “fancy shapes.”
Cut is graded in terms of proportion, symmetry, and finish. When a diamond is skillfully cut, light will reflect and move through it efficiently—thereby creating the breathtaking sparkle that diamonds are famous for. The Gemological Institute of America has set a standard grading system by which diamonds are rated. The highest rating is Excellent, followed by Very Good, Good, Fair, and Poor. Because cut has such a great impact on the stone’s appearance, it should be a heavily considered factor when diamond shopping.
