GIA Certificates - The Diamond

The Gemological Institute of America, known as GIA, is the world’s leading and most respected name in diamond quality grading. A diamond report issued by GIA provides the ultimate in expert certification, attesting your diamond’s identity, characteristics, and quality.

As the creator of the 4Cs diamond grading system (color, clarity, cut, and carat weight), GIA ensures the integrity and accuracy of every diamond report it issues. So if you are looking for the most trusted report for your diamond, this is the most widely recognized and respected of them all.

GIA certified

What It Includes
The diamond report issued with all our GIA-graded diamonds is called a GIA Diamond Dossier®. It includes a full assessment of the 4Cs - color, clarity, cut, and carat weight - and additional grading information like polish, symmetry, and fluorescence.

Each GIA diamond report also includes a graphic diagram representing your diamond’s actual proportions.

Additionally, your GIA-graded diamond comes with a microscopic laser inscription of its report number for easy identification. You can verify this number on the GIA website to confirm that the information matches what is archived in the GIA report database. This provides you with an additional level of assurance.

For us, the GIA diamond certificate is an indisputable, and most trusted ‘seal of quality’. It assures you that the diamond you have chosen is exactly what it should be, and nothing less.

Does this Make an GIA Certified Diamond More Valuable?
Yes, without question, a diamond that has an GIA certificate is much more valuable and more sought after than a non-GIA certified diamond. The report together with the laser inscription gives any buyer or new owner of your diamond the same peace of mind it gave you when you purchased it.

Are These Diamonds Conflict Free?
As with all the diamonds we sell, each one of our GIA certified diamonds is conflict-free.

Are GIA Certified Diamond Any Different to Other Diamonds?
Yes, an GIA certified diamond is exactly what is says it is; nothing more and nothing less. When you buy a non-certified diamond, you are relying solely on the retailer's opinion.

Why is a GIA Certified Diamond More Expensive Than an SKD Certified Diamond?
Because the GIA laboratory is the biggest international, globally recognised diamond and gem laboratory in the world. SKD is a London-based laboratory.
