Lab grown diamonds are having a major moment right now — and for good reason. Not only are lab diamonds notably more affordable than natural diamonds, but they’re also just as “real.” While lab diamonds are created in special, man-made conditions, they still have the exact same physical, chemical, and optical properties as mined diamonds — which is why here at Oui by Jean Dousset, all of our handcrafted engagement rings feature high-quality lab diamond center stones. (So you don’t have to sacrifice quality or size to get the luxurious ring of your dreams. And with the money you’ll be saving, you and your boo might be able to spend a little bit more toward that dreamy honeymoon fund.)

Still, as with natural diamonds, not all diamonds that are lab grown are equal. From the technology used to create the diamond to the diamond’s cut and polishing, numerous factors must be considered when assessing a lab diamond’s quality — and Jean Dousset’s team of experts takes this assessment process very seriously. Every Oui lab diamond is made with the best technology on the market and hand-selected for the stone’s beauty and cut. Basically, the lab diamond you select for your sparkling Oui design is the crème de la crème of diamonds — period. So what could possibly be the cherry on top of diamonds that are already optimal, beautiful, and exquisitely cut? A stamp of approval from the world’s foremost authority in diamond certification: the Gemological Institute of America (GIA). At Oui, our collection exclusively features GIA-certified lab grown diamonds, ensuring that all of our lab diamonds are verifiably high-quality. Keep reading to learn more about why we love GIA-certified diamonds.

What does “GIA-certified” really mean?

If you’ve been on your engagement ring hunt for a while now, you’ve probably heard the phrase “GIA-certified” quite a bit already — especially if you’ve been eyeing natural, mined diamonds. But, as a refresher, GIA-certified diamonds are diamonds that have been evaluated by the GIA per the organization’s tried-and-true International Diamond Grading System, which is the only worldwide standard for appraising diamond quality. Through this process, diamonds are assigned a grade for each of their 4Cs — aka cut, clarity, color, and carat weight.

Yet, even though GIA’s trusted, world-class grading system has been utilized for over 80 years now, it wasn’t until 2007 that the institute began grading lab grown diamonds. And while today it’s easier than ever for consumers to find a gorgeous, high-quality diamond, very few jewelry brands offering lab diamonds go the extra mile to make sure that all of their lab grown diamonds are graded and certified by GIA. Enter: Oui engagement rings, which exclusively feature GIA-certified lab grown diamonds. Because a top-tier bride-to-be deserves a top-tier diamond, and at Jean Dousset, we believe a lab grown diamond should be held to the same quality standards as a mined diamond.

Why does GIA grade lab grown diamonds?

Since lab grown diamonds have a different origin than mined diamonds, you might be wondering what criteria a lab diamond must meet to become GIA-certified, and you may even be asking yourself why a lab diamond should be certified in the first place. Well, the truth is that a lab diamond doesn’t have to be GIA-certified; in fact, many lab grown diamonds on the market aren’t. (Scary, right?) There are a variety of “reports” with which a lab diamond can be graded. But facts are facts: GIA’s grading system is the worldwide standard, and the report that comes with a GIA-certified lab diamond represents the highest measure of reliability, consistency, and integrity.

Most importantly, lab grown diamonds graded by GIA are, quite literally, held to a higher standard than those assessed by other entities. No other grading report in the industry notes whether or not a lab grown diamond has been artificially treated post-growth (a lower-cost “enhancement” process that affects the chemical properties of a diamond, its 4Cs, and thus, its value). Thus, the GIA-certified lab grown diamond you choose to invest in is guaranteed to be as physically and optically outstanding as the natural diamonds Mother Earth has to offer.

Why is GIA certification important for lab grown diamonds?

Here at Jean Dousset, we believe in quality over everything, and that obsession remains steady, no matter if we’re helping you find the perfect lab grown diamond for your Oui by Jean Dousset creation or custom-crafting a breathtaking design from our bespoke collection.

But we also understand that it’s easy to feel like some concepts — say, accessible lab grown diamonds that are just as luxurious and brilliant as their pricier, natural counterparts — can sound too good to be true. That’s why we consider the GIA certification of lab grown diamonds to be so indispensable. Regardless of our customers’ unique budgets or personal styles, Oui is all about giving everyone the opportunity to buy the engagement ring they want, without sacrificing paramount qualities like craftsmanship, value, size, and, of course, beauty. Lab diamonds are equally as remarkable creations as natural diamonds — and as such, we believe that an internationally recognized diamond certification should serve as a standard of excellence in the budding lab-grown space, too.

If you would like a two-tone precious metal combination for your engagement ring please reach out to our customer service team for assistance. Two-tone combinations include 18k white gold prongs and an 18k rose gold or 18k yellow gold band. Some clients prefer 18k white gold prongs to blend better with the color of the diamond center stone.


18K Rose Gold
If you have a passion for pink, rose gold is a perfect match for your ring that will blush on its own.


18K White Gold
For those looking for a vintage white, our white gold is rhodium plated* to give extra whiteness and scratch protection. Over time the tone of white gold will soften.


18K Yellow Gold
Yellow gold is an ideal fit for those looking for a warmer tone.


For a heavier metal with a white appearance, platinum could be the metal for you. It is also hypoallergenic.


*Rhodium is a liquid plating applied as a final finishing to all of our 18K White Gold and Platinum jewelry. It adds extra brightness + whiteness as well as scratch protection and is also hypoallergenic.
