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.
Diamond Size: 1.00
The international unit of weight used for measuring diamonds and gemstones, 1 carat is equal to 200 milligrams, or 0.2 grams. A specific measurement of a diamond's weight, carat weight alone may not accurately represent a diamond's visual size.
We recommend considering carat weight along with two other influential characteristics: the overall dimensions and the cut grade of the diamond.
