James Allen Company history
JamesAllen.com was founded in 2006 by four industry heavyweights with a combined 60+ years of experience in the diamond and jewelry business. James Allen was created to marry their deep industry knowledge with expertise in online direct-to-consumer sales and unparalleled customer service powered by technology and a pioneering online shopping approach.
Until 2017 James Allen was the largest privately held online diamond and bridal jewelry retailer in the world when Signet, the diamond conglomerate, acquired it. They clearly saw value in adding the leading online diamond vendor to their portfolio. And as you can read in our James Allen review below, there is a good reason for that. We’re happy to report that the ownership has not in any way harmed the customer service and value, and JamesAllen.com continues to be the leading online diamond seller.
James Allen’s Unique online shopping experience
James Allen has led the online diamond shopping experience by making it possible to scrutinize every single diamond detail right from your computer or smartphone without leaving the couch. Contrary to what you might think, comparing stones side by side on your screen gives a much more true and honest view of the stone you’re buying and makes it possible to compare diamonds side by side. This is a game-changing improvement over the shopping experience at physical stores.
When you shop for diamonds at a store, you can be sure that the lighting is anything but natural and will make any diamond sparkly much more than in broad daylight. And you won’t be able to zoom in and look through stones at your own leisure like you can on JamesAllen.com (but you will be pressured to purchase a sub-par diamond by commission-incentivized sellers).
360-degree HD views
On James Allen’s website, you can enjoy full 360-degree high-resolution 3D views of every single stone (though it’ll take you a while to view them all). You can see all stones magnified 40X, so you are sure not to miss any details or imperfections (read our buying guide to learn why you might actually want some imperfections).
In addition, you can now also try their “Virtual Ring Sizer” so you are sure you’ll end up with the right ring and diamond size (and if you don’t, just avail of their free 30-day exchanges and refunds).
Live-chatting with trained gemologists at James Allen
While examining the diamonds, you can chat 24/7 with their non-commissioned certified gemologists and ask any questions. You can spin and highlight features of the diamond, and the gemologist can follow along. This way, you can have a fully interactive discussion about the details of their stones. Who needs to deal with a pushy diamond salesperson in a store now?
If you do happen to be in either Washington D.C. or New York City, you can visit any of their two physical stores. Still, there really is no reason since their full inventory is only available online. Their online shopping experience is much better than in any physical store (and any other online jeweler).
Competitive prices at James Allen
Lab-grown diamonds are typically 30-40% lower than mined equivalents. So when you shop James Allen’s lab-created selection, you are sure to save – or be able to upgrade with the same budget!
Compared to some of the lab-grown only diamond sellers, James Allen’s prices are typically slightly higher than the lowest-priced jewelers. But this minor premium is what you pay to have access to trained gemologists 24/7 and their truly unique shopping experience. This is a small price to pay to be able to inspect your diamond investment in the finest details and to be 100% certain of every single aspect of your diamond purchase (mined as well as lab-created).
Compared to traditional diamond and jewelry sellers, you’ll still find that JamesAllen.com offers some of the absolute best prices both online and offline, and nowhere will you find the same level of service and certainty about your diamond purchase.
James Allen lab-grown diamond selection
Since James Allen sells both mined and lab-created diamonds, they naturally have a broader selection than most sellers who are solely focused on lab-grown diamonds. At the time of writing, they have close to 450,000 in their inventory. Their selection of lab-created diamonds is smaller at around 50,000, but it’s still among the largest inventories of lab-grown loose diamonds on the market. And it’s more than enough to guarantee that you will be able to find the perfect match.
Ignoring a few specialized sellers, James Allen still offers one of the widest selections of lab-created diamonds, and it will not be a problem finding a diamond that matches your specific 4Cs.
One area where James Allen has a clear advantage is their unmatched variety and selection of fancy colored diamonds (blue, green, pink, yellow, and more). However, the selection of lab-grown fancy-colored stones is limited.
Another thing to note is that all of their colorless and fancy yellow lab-grown diamonds have not received any post‑growth treatment or color enhancement. The practice is debated in the diamond industry, but many prefer their lab-created diamond not to be treated (we don’t think it’s a problem, but treatment could lower potential future resale value).
When it comes to jewelry settings (rings, studs, etc.) James Allen far surpasses most competitors, and their wide-ranging ability to customize (plus throwing in free engraving) puts them ahead of the pack.
Free shipping and free returns at James Allen
James Allen offers free FedEx Overnight shipping on every order and free return shipping on all orders (currently US only). Orders are shipped securely overnight following a 7-10 day production time and offer flexible delivery options to avoid ruining any surprises.

30-day money-back guarantee at James Allen
James Allen offers risk-free 30-day full refunds and free exchanges. The process is straightforward, and they’ll help you through every step and guide you in case of an exchange.
With their risk-free money-back guarantee you can shop confidently at James Allen knowing that you can return any purchases. But, if you rely on their expert guidance, we doubt you’ll have to. Regardless, it’s nice to have the peace of mind.
James Allen environmental and human impact
Since James Allen is not dedicated solely to selling lab-grown diamonds, these do not feature prominently on their website, nor do they devote space to detail the environmental and social footprints of their man-made diamonds.
That being said, the general benefits of lab-grown diamonds, of course, also apply to lab-created diamonds bought at JamesAllen.com. These include benefits to the local environment and communities by avoiding land and animal habitat disturbances and decreasing mineral waste. Human and workers’ rights violations, poor safety, political turmoil, and conflict are likewise not issues at diamond laboratories.
On a broader scale, the production of lab-grown diamonds requires only 1/7th of what diamond mining does, and the energy usage is on average 25 times lower, benefiting the global climate.
While not specified, in our James Allen review we must assume that clean energy is not wholly used to produce lab-created diamonds sold at James Allen, unlike the lab-grown diamonds Vrai uses. So there are still a few benefits that can still be reaped.

Lab-grown diamond certification at James Allen
Lab-grown diamonds are graded and certified by the same laboratories and grading institutions as mined diamonds and use the same standards and procedures. You can, therefore, rest assured that your lab-created diamond is exactly the same as a mined diamond, and you can compare them like-for-like using the 4C grading system (read more about the 4Cs here).
All diamonds purchased through James Allen are graded and certified by IGI, AGS, and GIA, the highest regarded diamond labs, so you can rest assured that you get exactly what you expect.
James Allen Lab-grown Diamond Review Verdict
Throughout our James Allen review, we have repeatedly been impressed by their superior customer service, the unparalleled shopping experience and use of technology, and trained on-call gemologists to aid you through the buying process. This has not changed for our 2022 updated review.
