What is the difference between egl and gia diamonds

Brief about GIA:. In the global diamond industry, GIA reports are highly recognized for their strict grading and proven consistency. The most popular accomplishments of GIA so far are the grading of Hope diamond in and the establishment of the 4Cs grading system for diamonds in Besides diamond grading certification and laser inscription services, GIA also carries out intensive research work in the gemological field and provides educational services for diamond professionals and consumers.

EGL is well-known for introducing the SI3 rating in measuring the diamond clarity and pioneering the diamond grading techniques for stones with a less than one-carat weight. But it has also been in a controversial consumer lawsuit for over grading diamonds.

The fundamental difference between EGL vs GIA diamond grading is that GIA diamonds are examined by a minimum of 4 gem experts before the certificate is documented, which leads to consistency in the certification process. EGL certified diamonds will be usually graded down two on color and one on clarity than that of GIA certified diamonds. Therefore, the GIA certified diamonds are usually considered as a more reliable choice for buyers.

Furthermore, GIA offers a post-cert option, which means the companies send and pay their diamond only for the grading service, and after receiving the results they decide if they want to pay for the certificate to be printed. However, Carat weight grading of diamonds is not subjective as the other Cs — Color, Cut, and Clarity. Carat is simply a measurement of the weight of the diamond so it never differs between any gemological laboratories not even in GIA or EGL. Or does it make a huge difference if a diamond is a D color graded or an F color graded?

Well, we suggest you see the difference for yourself. This nonprofit institute prides itself on being a reliable source of information on standards and education of the gemstone industry. GIA was originally founded by Robert M. Shipley, a middle-aged former retail jeweler from Wichita, Kansas. Although this time around was during the Great Depression, Shipley managed to establish an institute that, to this day, aspiring jewelers flock to for instruction. Throughout the years, GIA schools have opened up across Europe and Asia, making its knowledge more widespread; eventually, there will be schools across the globe.

In , GIA established the 4Cs, the most popular grading system for diamonds. As opposed to the EGL certificate which is also a strong form of grading , the GIA has the strictest grading system among all of the most popular laboratories.

It is also known as the most consistent grading system. The GIA is considered the basis for diamond grading since it developed the 4Cs, and most other laboratories are compared to it.

EGL, or European Gemological Laboratory, is one of the oldest and largest gemological laboratories in the world. These are three major US diamond laboratories:. H color. VS2 clarity. It is important to know that Diamond Laboratories certify all diamonds submitted for grading and any certificate [including GIA] does not guarantee the brilliance, desirability or correct value of any diamond.

Their staff of 1, employees includes scientists, certified diamond graders, and educators. GIA is credited with standardizing the grading industry by introducing the Four Cs and other widely used grading techniques. They offer diamond grading and laser inscription services, as well as a wide range of educational services for diamond professionals and consumers.

Each GIA diamond is carefully evaluated by at least four expert gemologists who are chosen at random to guarantee an unbiased evaluation. As a general rule, an EGL certified diamond will compare equally in quality to a GIA certified diamond that is graded two color grades and one clarity grade lower.
