What are GIA, AGS, IGI and EGL Diamond Certificates?

A diamond certificate (also known as diamond grading report) is an important document that tells the quality and authenticity of your diamond. It adds value to the price you pay for the precious piece of stone. A certificate rules out whether your diamond is natural (mined) or artificial (created in a lab) by terming it as GIA, AGS, IGI and EGL certified loose diamond.

It is not only a validity report for your diamond but also a value-enhancement document.

What Are The Diamond Grade Certification Labs?

There are several gemological institutes in the market you can pick when you buy loose diamonds online. They serve the same purpose; they certify the diamonds you purchase. They follow a systemic and scientific procedure to evaluate the gems in the form of certified loose diamonds.

How Diamond Grade Certification Labs Differ?

They differ depending upon the type of evaluations they do and several factors they take into consideration for the assessment.

Some labs are rigorous in their evaluation metrics. Others have relaxed standards and show inconsistencies. You may try testing the same diamond in more than one of these labs with substandard evaluation metrics.

As a potential customer, you wouldn’t want to pay more for your purchase. An incorrect report of your diamond assessment can affect your diamond’s worth severely. Some gemological labs may even unfairly up the price of the diamond you want to purchase.

There are four significant types of diamond grading institutes. They are AGS, GIA, IGI, and EGL. Here are some differences:

GIA (Gemological Institute of America) is the most trusted lab in the whole world. It is also the most preferred lab. Its headquarter is in California. Along with diamond grading and certification, it also is proficient in upgrading itself by researching in the fast-paced technological world.

AGS (American Gemological Society) based out of Las Vegas is known for its research in diamond cut grading. It is another known name in the market for diamond grading. It is the second name after GIA that you can rely on. It, too, is trustworthy because of its strict evaluation metrics.

Unlike the conventional method of grading, AGS uses a 0 to 10 scale for clarity and cut evaluation.

They use ray-tracing assessment technology that measures the diamond’s light performance. With this state-of-the-art technology, AGS gives the best right result with precision.

Some diamond dealers prefer AGS to GIA for a better cut grading assessment. They send the more neatly cut diamonds to AGS because of their technological advancement in the field.

IGI (International Gemological Institute) Based in Antwerp, Belgium, it provides diamond grading assessment on polished diamonds. They are well known in the USA and Asia. Even though it has a strong presence in the market, it is not a very reliable institute. In comparison to GIA and AGS, they have less credibility in the market.

EGL (European Gemological Laboratory) is a European company; it has a good spread in the world market. They have introduced the SI3 system of clarity rating. However, it is not a reliable grading system.
