The Diamond Certification Process

What is evaluated?


The diamond is weighed and measured to determine its carat weight and dimensions.

2. Diamond Cut Evaluation

The cut of the diamond is examined and measured for its proportions, symmetry, and polish. This is a critical step that significantly influences the diamond's sparkle.

3. Color Grading

The diamond is examined for its color, and it is compared to a set of master stones to determine its color grade on a scale from D (colorless) to Z (light yellow or brown).

4. clarity grading

The gemologist assesses the diamond's clarity by examining it under magnification to identify any internal or external flaws (inclusions or blemishes).

The Final Grading Report

Once each diamond is meticulously analyzed, a report of all the grading variables is documented on a certificate. When you purchase your diamond, your jeweler will provide you with the certificate of authenticity. Investing in a GIA-certified diamond guarantees genuine worth and unquestionable quality.

GIA Diamonds FAQ

What is GIA certification for diamonds?  

GIA certification for diamonds is a process by which the Gemological Institute of America (GIA) evaluates a diamond based on its four Cs - Carat, Cut, Color, and Clarity. This assessment is then documented in a report, providing an objective, third-party analysis of the diamond's quality. 

What does "GIA" stand for?

GIA stands for the Gemological Institute of America. It's a nonprofit institute dedicated to research and education in the field of gemology. GIA's diamond grading system is recognized internationally as the standard for diamond evaluation.

How do I know if my diamond is certified by GIA?  

A diamond certified by the GIA will come with a Diamond Grading Report. This document will have a unique report number, which you can verify on the GIA Report Check service available on the GIA's website.

What is the difference between GIA and AGS diamond certification?  

While both the GIA and the American Gem Society (AGS) provide reliable diamond grading services, there are slight differences. AGS uses a 0-10 grading scale for its diamonds, with 0 being the best, whereas GIA grades on a scale from D (best) to Z. Furthermore, AGS provides a cut grade for fancy shapes while GIA does not.

Are GIA diamonds more expensive than other diamonds?

While the GIA certification itself does not increase a diamond's value, diamonds with a GIA certificate may be priced higher. This is because they provide a guarantee of the diamond's quality and characteristics, which can increase buyer confidence and willingness to pay a premium.

What is the best way to find GIA certified diamonds?  

The best way to find GIA certified diamonds is to purchase from reputable jewelers who provide GIA grading reports with their diamonds. Reach out to Dallas Diamond Factory to schedule a complimentary diamond appointment, where you can browse their selection of GIA Diamonds.
