Diamond Grading Bodies

Although you can teach yourself everything you need to know about diamonds and thus measure the quality with your own eyes, you would still need an accurate and objective grading report or certificate.

Even experts have difficulty estimating the exact color of a diamond. That’s why it’s important to only choose a diamond that’s graded by one of the best grading labs. This, in turn, will enable you to estimate the market value of your diamond way more precisely.

 

Here are the largest & most well-known grading bodies used by Luxor Jewelers:

GIA: Gemological Institute Of America

As the leading diamond lab in the world, GIA has the highest standards and is the most widely used service. They’re dubbed as the most trusted because of their consistency.

GIA is also known for educational services and gemological research that allows them to keep up with the latest technologies in grading and certification.

You’ll find many GIA offices around the world with over 1,400 certified graders, scientists, and educators.

IGI: International Gemological Institute

IGI is based in Antwerp, Belgium and is renowned in Asian countries. It’s also the second most recognized gemological lab in the world. In fact, a lot of polished diamonds in the market are actually graded by IGI.

AGS: American Gemological Society

AGS is on par with GIA when it comes to high standards and consistency in grading. They’re known for their scientific approach and alphabetical rating system.

EGL: European Gemological Laboratory

EGL rules in Europe and is globally consolidated as well. It’s infamous for grading SI3 diamonds but is also well-known for developing grading techniques for diamonds less than 1 carat.
