Both rough and cut diamonds are separated and graded based on these four characteristics.This will help you immensely when you are comparison shopping for diamonds.Diamond Cut Quality

When a diamond has a high quality cut (ideal cut), incident light will enter the stone through the table and crown, traveling toward the pavilion where it reflects from one side to the other before bouncing back out of the diamond's table toward the observer's eye (see Fig.This phenomenon is referred to as "light return" (Fig.The "Shallow Cut" and "Deep Cut" examples in Fig.Modern Round Brilliant diamond reaches the pavilion facets and then leaks out from the sides or bottom of the diamond rather than reflecting back to the eye through the table.Less light reflected back to the eye means less "Brilliance".In the "Ideal Cut" example, most of the light entering through the table is reflected back towards the observer from the pavilion facets.Keep in mind that the variance in proportions between an "Ideal Cut" (ideal make) and a "Fair, Poor, Shallow or Deep Cut" may be difficult to discern to the novice observer, although there will be a lack of brilliance, scintillation, and fire.Cut quality is divided into several grades listed below.Cut Proportions
In the past, the "Cut" quality of the "4 Cs" was the most difficult part for a consumer to understand when selecting a good diamond because a GIA or AGS certificate did not show the important measurements influencing cut (i.Only a trained eye could see the quality of a good cut.The proportion and symmetry of the cuts as well as the quality of the polish are factors in determining the overall quality of the cut.Common cutting problems can occur during the faceting process, when one incorrect facet angle can throw off the symmetry of the entire stone.The chart below shows several common problems to look for.Certification

A perfectly proportioned ideal cut that is cut to the exacting specifications of a Tolkowsky Cut, Eppler Cut (European Standard), or a Scan D."EightStar" diamond was cut in 1985 by Kioyishi Higuchi for Japanese businessman and FireScope manufacturer, Takanori Tamura.The shape of the diamond cut is heavily dependent upon the original shape of the rough stone.Asymmetrical raw crystals such as macles are usually cut in a "Fancy" style.Popular fancy cuts include the "Baguette" (bread loaf), "Marquise" or "Navette" (little boat), "Princess" (square outline), "Heart", "Briolette" (a form of Rose cut), and the Pear.The "fancy cuts" are generally not held to the same strict standards as Round Brilliants.Independent Diamond Testing Laboratories
