EGL Certified Diamonds: What You Need to Know About Them

Diamonds are one of the world’s most precious gemstones. They are also the most common choice for use in fine jewelry, wedding and engagement jewelry, especially in rings. Due to their wide scale use, they are often selected based on four major factors: cut, clarity, color and carat size. Many gemological testing laboratories provide services to grade diamonds based on all of the above to make sure they are fit for commercial use. One of these labs includes the EGL(European Gemological Laboratory). In this blog, we will tell you all you need to know about EGL certified diamonds before making a purchase.

What are EGL Certified Diamonds?

The EGL is an organization that operates a network of gemological laboratories in locations including the USA, London, Paris, Antwerp, Mumbai, Johannesburg, Seoul, Hong Kong and Tel Aviv. Founded in 1974, it is one of the most popular choices to obtain graded diamond reports. They specialize in grading techniques for diamonds that weigh less than one carat as well as for introducing the “SI3” diamond clarity rating, which is a step further below from the low diamond clarity rating of S12, a diamond graded as having small inclusions.

EGL vs GIA Certified Diamonds

The GIA(Gemological Institute of America) was established in 1931. Considered a global authority on gemstone grading, as of today the GIA has branches in the USA, Antwerp, Florence, Tel Aviv, Mumbai, Moscow, Gaborone, Johannesburg, Beijing, Hong Kong, Seoul, Tokyo, Osaka, Taipei, and Bangkok.

Generally, the GIA takes the lead where it comes to reliable diamond grading reports. Compared to the EGL, the GIA has stricter testing standards, with multiple stages of testing to grade a single diamond. EGL certified diamond reports, on the other hand, will differ from branch to branch, with the EGL USA being slightly stricter than the international centres. 

When it comes to the overall quality, a GIA certified diamond will rank greater than an EGL certified diamond, which is graded two color grades and one clarity grade lower. However, the EGL is considered to be a more affordable alternative to GIA. Due to their strict quality protocols, the cost of a diamond graded from GIA goes up exponentially. This is the reason why some prioritize an EGL certified diamond over a GIA certified one.

EGL Certified Diamonds: A conclusion

Due to inconsistent certification results, the EGL might not be considered a reliable authority on diamond grading. Some argue that the low rating of S13 is made up in order to market diamonds that are not even fit for use in commercial jewelry. 

While there is no such thing as flawless test reports and there is always the benefit for doubt, the GIA comes close to perfect. Not only does the GIA provide diamond grading and gemstone testing services, it is also a lead center for learning gemology, research and jewelry education and design training. Their strict evaluation makes them the leading authority for diamond grading and certification.
