EGL Certified Diamonds
The European Gemological Laboratory more commonly known as the EGL is one of the largest and oldest independent gemological institutions. Originally part of an international network founded in Europe in 1974, EGL USA opened its first U.S. lab in the heart of New York's international diamond and jewelry district in 1977. The EGL is credited with introducing new approaches to grading diamonds, including the grading of diamonds less than one carat in size. In 1997, EGL unveiled the S13 designation for grading diamond clarity, a standard that the world diamond community has come to embrace. Thanks to its commitment to gemological excellence and more than a quarter century of experience, the EGL is one of the world's most prestigious laboratories.
Methodology
An EGL grading report is based on thorough scrutiny of every facet and detail of the diamond being considered. Each diamond passes through the hands of at least eight professionals, four of whom are trained gemologists.
- Weight and measurement are recorded, and culet and girdle thickness are noted.
- Color is graded in scientifically calibrated lighting conditions, and the stone is compared to a set of master diamonds with known color grades. Three color graders must agree before the diamond is assigned a color grade.
- Clarity is determined by graders who use a zoom binocular microscope to inspect every facet of the diamond for inclusions (internal) and blemishes (external) that could affect clarity. Locations of inclusions are plotted on a diamond diagram.
- Polish and symmetry are graded based on a careful inspection of the diamond's cut finish.

Cut Grade
The EGL evaluates the cut grade of a diamond based on a meticulous examination of the stone's proportions and cut. Polish and symmetry as well as a diamond's ability to exude brilliance are considered in determining cut grade.
