Your GIA Certification, Explained

A GIA certification is an official document detailing the nitty-gritty of your unique diamond. Why’s it important? Read on to find out.

GIA Certification

First of all, what’s a GIA certification?

A GIA certification (so named because it’s issued by the Gemological Institute of America) is a type of diamond certification: a document that describes in detail all the unique characteristics of your diamond. An official GIA inspector analyzes your diamond thoroughly and records its physical attributes in the certificate. The 4 C’s (Cut, Color, Clarity, and Carat Weight) are covered exhaustively. No two diamonds will have identical GIA certificates.

In short, you can think of a GIA certification as your diamond’s “birth certificate.”

“What I’m most pleased with is how sparkly the diamonds are. I’m so glad I chose the 3 prong martini style, they don’t stick out or droop. They fit as flush to the ear as possible if that’s the look you’d prefer.” -Joyce J.

“I absolutely love my new earring studs! I was able to style them exactly how I wanted using the stones and metal I wanted. Couldn’t ask for a better experience.” -Matt T.

Is a GIA certification important? 

Well, yes and no. 

Yes: The GIA certification allows gemologists to identify, price, and appraise your diamond. By documenting its one-of-a-kind characteristics, a diamond certificate ensures that your stone is unmistakable.

No: You wear a diamond for the sparkle, not the certification. The GIA certification often comes in handy at the beginning of your diamond’s life – as you buy, appraise, and insure your diamond – then usually spends the rest of its days in a file cabinet.

To really understand the aspects of your diamond described in the GIA certification, you have to see them with your own eyes. With James Allen’s Diamond Display technology, you can view your diamond in 360° HD and up to 40x magnification. Then you’ll truly understand your diamond’s features.

Earth Created Vs. Lab Created Diamonds?

Lab created diamonds and earth-created diamonds both come with diamond certifications. That’s because lab created diamonds and earth created diamonds are, well, diamonds. And since both grow organically (one underground, one in a lab) they both form their own unique, gradable characteristics. In fact, even professional gemologists can’t reliably tell the difference between earth-created and lab-created diamonds.
