Choosing the perfect engagement ring is one of life’s most exciting decisions, and verifying a diamond's certificate is a crucial step in the process. This document authenticates the diamond’s quality, ensuring you’re investing in a genuine stone. But how do you verify it?

What Is a Diamond Certificate?

A diamond certificate, or grading report, is a document that provides an unbiased evaluation of a diamond's quality. It includes key information like carat weight, color, clarity, and cut—known as the 4Cs. It’s issued by independent gemological laboratories that use professional standards to assess a diamond. The two most respected laboratories are IGI (International Gemological Institute) and GIA (Gemological Institute of America).

How to Verify Your Diamond’s Certificate?

Check the Serial Number: Every diamond graded by IGI or GIA comes with a unique serial number laser-inscribed on the diamond’s girdle. This number should match the one on the certificate.

Visit the Laboratory’s Website: IGI and GIA provide online tools where you can verify a diamond's details. Simply enter the serial number, and you can access the original grading report. This step ensures that your certificate is legitimate and that the diamond’s specifications match what was sold to you.

Examine the Certificate: Ensure the certificate includes details like the diamond’s dimensions, 4Cs, fluorescence, and any inclusions. GIA reports often include a diamond plot, which shows a visual map of its inclusions.

Look for Physical Security Features: Authentic certificates have advanced security features, such as holograms or microtext, which are difficult to forge.

Why Trust IGI and GIA Certificates?

Both IGI and GIA are globally recognized and trusted. GIA is known for its strict grading standards, while IGI offers more affordable grading options without compromising quality. Both institutes provide thorough grading reports that are accepted and respected by jewelers worldwide.

Conclusion

A diamond grading report or certificate is the blueprint for a diamond.  It will describe a diamond's exact measurements and carat weight, its colour and clarity, as well as details of its cut and quality.

This information may not be important to all looking to purchase a diamond but for the vast majority a diamond grading report ensures the diamond they are purchasing matches the diamond specifications they are paying for.

For the most part diamond grading reports usually only come with diamonds a quarter carat weight, 0.25ct, and above.

Just like finger prints all natural diamonds have natural characteristics.  These characteristics are usually described as flaws or inclusions and each and every diamond is different.  A report will map out the inclusions showing you exactly how many, what type and where any flaws are located on a diamond.

There are many different laboratories who grade diamonds and unfortunately they do not all work to the same or even similar guiding principles.  A diamond that has been graded as an F in colour by EGL, the European Gemmological Institute, may only be graded as an H or even I by GIA, the Gemmological Institute of America.

Anyone who works in the diamond trade knows that GIA have the highest standards when grading diamonds and all reputable jewellers will be able to supply you diamonds with GIA grading reports.

Buying diamonds with GIA grading reports also allows you to be certain that the diamond has not been enhanced in any way e.g. fracture filling – a process where a diamonds inclusion is injected with a resin which makes the diamond clarity grade appear to go from I2 – Si1.  As this process is completely reversible by immersing the enhanced diamond in hot water or even exposing it to strong sunlight I wholeheartedly do not ever recommend purchasing enhanced diamonds.
