What's The Difference Between GIA and EGL Grading Reports?

Many customers encounter different grading reports and find it puzzling as to what is the difference between GIA, EGL and other diamond certifications. It becomes an even more important question when you notice a significant price discrepancy between two diamonds of the same carat weight, graded the same cut, color, and clarity. An understand as to what a grading report is can help shed some light on this mystery.

Generally speaking a grading report is an expert opinion given by a gemological laboratory.
The diamond grading system is based on the 4C's: carat, cut, color, and clarity. Both GIA and EGL are independent regarding laboratories, and both organizations will grade any diamond for a fee. Some diamond vendors choose to grade their diamonds with GIA (Gemological Institute of America) while others decide to grade their diamonds with EGL, (Europe Gemological Laboratory). 

GIA is a none profit organization that developed the diamond grading system that is in use today.  Since GIA's establishment many other organizations have emerged using GIA's grading system, but with different grading standards. This is what makes it difficult for customers to comparison shop because it is not an even grading system.

Grading Scale

A diamond graded G color according to EGL might get an H or I grade when graded according to GIA's standards. At the same time a diamond graded VS1 clarity according to EGL might actually get a VS2 or SI1 grade according to GIA. This is the reason why some diamond dealers only choose to submit their diamonds to EGL laboratories to achieve the better grading report because GIA has the stricter standards, whereas EGL may sometimes be more lenient in their grading policy (relative to GIA).

Price Difference

If you want to compare the price of an EGL graded diamond to a GIA graded diamond, drop the EGL grade of the diamond you are considering by two color grades and one clarity grade. If you find that even with these adjustments the EGL diamond you are considering is still more affordable than a the GIA graded diamond, than it is priced well and may be a good buy.
By using this method, you will also find larger stones graded by EGL that are within your budget.


Currently, in the United States, GIA graded diamonds are the most popular choice, with EGL as the runner up. EGL graded diamonds have the majority market share in certain parts of the United States, such as Texas and Florida. In Canada and Europe, EGL grading reports are just as respected as GIA grading reports.

Over 90% of the diamonds carried by DreamStone.com are GIA certified diamonds.
