Difference between EGL and GIA

When it comes to diamonds, there are two main grading organizations: the Gemological Institute of America (GIA) and the European Gemological Laboratory (EGL). While both organizations use similar grading scales, there are some key differences between them. In this blog post, we’ll take a look at those differences and help you decide which organization is right for you.

What is EGL?

EGL is an acronym that stands for ‘European Gemological Laboratory’. EGL is an international gem certification laboratory with offices all over the world, including in the United States, Europe, and Asia. EGL was founded in 1974 by a group of independent gemologists with the aim of providing unbiased and accurate diamond grading reports. EGL was the first laboratory to use advanced computer technology for diamond grading, and today it is one of the most respected laboratories in the industry. EGL certificate holder can be sure of getting better value for their diamonds.

What is GIA?

GIA is a diamond grading system that ranks diamonds on a scale from D (no hue) to Z (a yellow hued diamond). GIA is the standard in the diamond industry and is used by almost all jewelers. GIA’s diamond grades are based on the 4 C’s – cut, color, clarity, and carat weight. GIA also offers other services such as diamond fluorescence testing, laser inscription, and diamond certification. GIA is a nonprofit organization that was founded in 1931. GIA’s headquarters are in New York City. GIA also has offices in London, Mumbai, Tokyo, Hong Kong, and other major cities around the world.

Difference between EGL and GIA

EGL and GIA are two of the most respected diamond grading organizations in the world. EGL was founded in 1974, while GIA was founded in 1931. Both EGL and GIA offer certification for loose diamonds and diamond jewelry. EGL is headquartered in the United States, while GIA is headquartered in Europe. EGL offers significantly lower prices for their certification services than GIA. However, GIA is generally considered to be more accurate in their grading than EGL. When choosing between EGL and GIA certification, it is important to consider your budget and your priorities. If accuracy is your priority, then GIA is the better option. However, if you are on a tight budget, then EGL may be a better option for you.


The two diamond grading laboratories, EGL and GIA, use different methods to grade diamonds. While both are considered reputable institutions, their grading results can sometimes differ. It is important for buyers to be aware of the differences between these two labs in order to make an informed purchase decision. If you are considering buying a diamond, be sure to research the different grades offered by EGL and GIA in order to get the best value for your money.
