Buying and owning a diamond involves a hefty amount of paperwork to go with it. An important aspect is to get the piece of the diamond graded for quality. EGL and GIA are labs that provide certifications for this purpose. Running a diamond through either of the two is a way to ensure that the material is legitimate.
- GIA (Gemological Institute of America) provides a more reliable and consistent diamond grading than EGL (European Gemological Laboratory).
- GIA is globally recognized, whereas EGL has limited recognition.
- EGL often gives higher color and clarity grades than GIA, which can mislead buyers into overpaying for diamonds.
EGL vs GIA
EGL (European Gemological Laboratory) is headquartered in Antwerp, Belgium, and has several locations around the world, known for its diamond grading system. GIA (Gemological Institute of America) is widely considered to be the most respected and trusted gemological laboratory in the world.
EGL was established in the year 1974. It is primarily a European network but also has branches in other countries such as EGL India, EGL USA, EGL Israel, and EGL South Africa. However, the grades can vary from lab to lab, as some of them are known to overestimate the quality of a diamond piece in terms of its colour and cut.
Meanwhile, GIA was founded in 1931 and had a fully functional grading system laid out by the year 1953. Even though there are many branches across the world, they are known to function as one unit. Unlike the former, GIA has strict and rigorous grading practices that ensure that the diamond is graded correctly.

What is EGL?
European Gemological Laboratories (EGL) is a profit-making independent organization that was established in 1974. Since then, many branches of the organization have been opened in different countries across the world. One of the most popular among them is EGL USA, which is known to be relatively rigorous as compared to other branches.
Many reviews on its grading process claim that the lab inflates the grade, which results in the customer overestimating the quality of a diamond. Due to this, he gets an overpriced product that is not really up to the standard.
An example of such a case is that when it comes to colour grading, EGL is known to provide a much higher grade as compared to others for the same piece of diamond. If the piece gets a D grade for colour at EGL, the same piece will get an F grade for colour at GIA. The same goes with cut grading, which is often misrepresented.
Regardless, EGL Europe claims that if a diamond dealer is not happy with the grading, he can get a certificate for free. This means that by giving out higher grades, they have more chances of making a profit out of it. The company even issues a quote on the replacement value of the diamond for every customer. However, these certifications do not cost much.
What is GIA?
Gemological Institute of America (GIA) is a non-profit independent organization founded in 1931 and fully functional by 1953. It has several branches across the world, which act as one unit. The company is known to issue grading reports that are scientific and unbiased. For this reason, getting a GIA certificate is a great way to test the authenticity of a diamond piece.
The reports that are issued for a diamond by GIA have a detailed description of weight, measurements, colour, and cut. These reports even tell the buyers if the diamond has undergone any kind of treatment. However, unlike EGL, GIA does not provide a quote on the diamond’s replacement value.
It must be noted that GIA does not mine or trade with diamonds. Neither does it deal with its valuation process. The organization steers clear of all commercial interests and solely works on providing diamond quality assessments. Due to this, the cost of getting a certificate is much higher as compared to other organizations.
Regardless, GIA is the world’s most reputable organization in the diamond assessment industry. It is known to have strict and rigorous grading processes that represents the characteristics of the diamond correctly.
