Summary of Grown Brilliance Review

Grown Brilliance specializes in lab-grown diamonds at low prices and strives to give users the best possible experience while shopping for sustainable diamonds. Have they succeeded? Keep reading our Grown Brilliance review to learn the answer.

Grown Brilliance sells loose lab-created diamonds, engagement rings, and fine diamond jewelry – all set with lab-grown diamonds only – the sustainable diamond choice. Grown Brilliance has built expertise in lab diamonds, and they focus on the many benefits of lab diamonds and make a point to highlight them.

Grown Brilliance started out focusing more on selling through platforms such as Amazon, but over time they have built their own site, which is now their main point of sale. In addition, they have revamped and greatly expanded the services and features on their site and now competing with leading lab diamond sellers such as James Allen, Clean Origin, Ritani, and Brilliant Earth.

We have updated our 2022 Grown Brilliance review to reflect the many recent updates that Grown Brilliance has made it its site, diamond offerings, and services. Keep reading our review of Grown Brilliance to learn how they stack up to the competition and if they have managed to join the ranks for the best places to buy lab-grown diamonds.

The prices at Grown Brilliance are very competitive, and their inventory of both loose and pre-set diamond jewelry is impressive, though not as large as, for example, Ritani’s. Our Grown Brilliance review also finds that Grown Brilliance offers an easy buying process and great features, though we miss a few key ones.

The service and support, including buying support through virtual appointments, a new feature, has been extensively revamped and improved. We find that they’re now on par with leading jewelers. Their chat support is helpful, friendly, and knowledgeable, albeit slightly slower to respond outside working hours than some competitors.

If you prefer to research on your own, which we recommend, you also do, Grown Brilliance gives you access to 360-degree videos, HD images, and almost all the information you need to make a qualified assessment and comparison.

The only thing missing is direct access to diamond certificates, which you must request (one at a time) by contacting support. We appreciate that they’re available, but immediate access to certificates is necessary to browse and compare several diamonds.

One key area where Grown Brilliance stands out is its extensive selection of fine jewelry and exclusive designs, such as its exclusive collaboration with designer Badgley Mischka. This puts Grown Brilliance closer to the likes of Vrai, Pandora Brilliance, and Kimaï but at a much more competitive price level, similar to leading sellers such as Clean Origin and Ritani. That is pretty impressive!

Another area is their unparalleled and market-leading ring design tool. It allows almost endless customizations of any ring and to see it rendered in 3D with your diamond of choice. Combined with their extensive selection of ring designs, we rank Grown Brilliance as the best place to buy lab-grown diamond engagement rings in 2022!

Grown Brilliance review: The Best Place for Lab-Grown Diamond Engagement Rings in 2023

All in all, our Grown Brilliance review finds that they offer excellent prices, a fantastic collection of fine and designer jewelry, a great selection of quality lab-created diamonds, and superior diamond inspection features. As a result, our Grown Brilliance review lands at a 4.7 out of 5 stars, and Grown Brilliance joins our list of the top-rated lab-grown diamond jewelers and is our pick as the best place to buy a lab-created diamond engagement ring.

Who are Grown Brilliance Diamonds?

Grown Brilliance was born an Amazon-first brand but has matured into a fully-fledged online diamond jeweler offering many of the premium features as leading established jewelers do. They now focus on selling through their own website, offering fantastic customer service and support.

Grown Brilliance is a relatively new jeweler on the market. However, the key team behind the brand all have years of expertise in the diamond business and the luxury product industry, such as Zales, Tag Heuer, and similar companies. Their combined experiences allow them to build and scale Grown Brilliance at an impressive pace and develop the brand into the renowned jewelry brand it is today.

Grown Brilliance is owned by a group of investors who have formed the holding company AJS Creations LLC.

Is Grown Brilliance legit?

Grown Brilliance is a legit and trustworthy online jeweler. Grown Brilliance is led and operated by people with decades of experience in the jewelry industry and other luxury products. Grown Brilliance started primarily operating through Amazon and later built out its current fully-featured website. Grown Brilliance has many happy customers, and their feedback is very positive. Grown Brilliance’s customer service is responsive, and you can reach them through phone, chat, and email. Their collaboration with Badgley Mischka adds significantly to their trustworthiness. Diamonds are certified by IGI, which is a reputable diamond institute, particularly for lab-grown diamonds.

Does Grown Brilliance have any stores?

Grown Brilliance started out online only but has just opened its first retail store on 5th Ave. in Manhattan, NY. You can set up appointments to visit them at their retail store on their website starting November 2022. Grown Brilliance still primarily sells through its own website,, and on Amazon. Generally, that means costs are lower, which is reflected in their prices. Keep reading our Grown Brilliance review to learn if they are the right place to buy lab-grown diamonds for you.

Where is Grown Brilliance located?

Grown Brilliance is opening its first retail store where you can book appointments starting November 1st, 2022. Their store is located in Manhattan, New York. The address for Grown Brilliance is 521 5th Avenue, Suite 820, New York, NY 10175. Read more about booking appointments at Grown Brilliance in the Grown Brilliance review.

Lab-grown diamonds only

Grown Brilliance exclusively sells lab-grown diamonds. They do this because they believe in the environmental and social benefits and are very outspoken about it, which we applaud. Grown Brilliance is committed to doing better than the traditional diamond industry and giving consumers a better and more conscious choice. We like that a lot.

Grown Brilliance Review - Dedicated to the better diamond choice of lab-grown diamonds.

In addition to only selling the sustainable and environmentally-friendly diamond choice, lab-grown diamonds, Grown Brilliance goes further. Similarly to Brilliant Earth and Vrai, they go out of their way to be as sustainable as possible. This includes their updated jewelry boxes made entirely of recycled materials.

The expert diamond content on the site, including about lab-grown diamonds, is not as built out as some competitors. We would have liked to see Grown Brilliance dedicate more resources to information about lab-created diamonds. However, we appreciate that they have invested in educating consumers about the false promise of conflict-free diamonds and the societal impact of mining. The rest you can read here at

Does Grown Brilliance sell real diamonds?

Grown Brilliance specializes in selling lab-grown diamonds and jewelry. Lab-grown diamonds are 100% real diamonds and precisely the same as mined diamonds. They are completely identical in their physical and chemical composition, and they sparkle at least as brightly. The only difference is that lab-grown diamonds are not pulled out of a mine and are a better choice for the environment. Grown Brilliance, therefore, sells completely real diamonds. Read our Grown Brilliance review to learn if you should buy lab-grown diamonds at Grown Brilliance.

Next, in our Grown Brilliance review, we’ll see if their focus on lab-grown diamonds translates into an excellent inventory of lab diamonds.

Grown Brilliance lab-grown diamond selection

As mentioned above in our Grown Brilliance review, they focus solely on lab diamonds. Grown Brilliance sells lab-grown diamonds as loose stones (meant to be used to create your own jewelry) or as pre-set jewelry with diamonds already selected for you.

We’ll start by looking at their loose lab-grown diamond inventory to gauge their inventory. Read our easy-to-follow lab-grown diamond buying guide if you need help going through this process.

Grown Brilliance loose lab-grown diamond inventory

At the time of the review, Grown Brilliance has 21,810 loose lab-grown diamonds to choose from. That is a very decent collection and almost three times more than when we last reviewed Grown Brilliance. Grown Brilliance’s inventory has…grown! It’s still fewer than the 110,000+ that Ritani, GemsNY, and have in store (or at least access to), but it’s comparable to many other leading online diamond jewelers.

To further assess the inventory of diamond jewelers, we also look for a typical and popular diamond. We call this our reference diamond. It’s a lab diamond suitable for many purposes and a popular weight. We also use this to compare prices later in our Grown Brilliance review.

Our reference diamond is a round brilliant-cut, weighing 0.93-1.07 carats (by going just under and over the popular 1-carat, you can sometimes find an excellent deal). The clarity is VS1-2 with an I or J color grade (some will prefer a higher color grade).

The cut, of course, is always the best. With lab-grown diamonds, most often certified by IGI, that is ideal. The diamonds at Grown Brilliance are certified by IGI, so that’s the grade we’ll use.

Loose diamond search at Grown Brilliance review.

Narrowing our search to these criteria, surprisingly, we only find two diamonds (last time, we found 54). To compare, we saw over 472 when searching Ritani’s database and over 100 qualified lab-grown diamonds at GemsNY (in our review, we found a lot too, but these are based on wholesale lists)!

Loose diamond search results at Grown Brilliance review.

We tried expanding our search and also performed numerous additional searches to gauge the diamond inventory profile of Grown Brilliance.

What we found was that, much like we found in our James Allen review, the inventory of Grown Brilliance skews towards higher color grades that we typically recommend. That’s not necessarily a bad thing; it depends on your preferences. For engagement rings, it’s common to aim for a slightly higher color grade and that fits well with Grown Brilliance’s top stop as our #1 place for lab-grown diamond engagement rings.

Expanded loose diamond search results at Grown Brilliance review.

We typically find that you can save by lowering the color grade, as we detail in our guide to lab-grown diamond colors. Later, in our Grown Brilliance review, we’ll look at the prices of both the reference diamond and the higher color-graded diamonds.

The inventory at Grown Brilliance is still bigger than what we saw at Friendly Diamonds and similar to the diamond inventory at Vrai and slightly smaller than at James Allen, but still very good. Notably, the diamonds we did find were all of outstanding quality, and most were eye clean (with no discernable inclusions or color issues).

So while the selection was a little smaller than other sellers, we found that most of the lab-grown diamonds they offered were of superb quality. You should thus still have a very good chance of finding a suitable diamond at Grown Brilliance. And as you can read later in our Grown Brilliance review, with their low prices, you definitely want to take a look.

Grown Brilliance pre-set lab-grown diamond inventory.

If you do not want to spend time searching for your diamond stones, you can pick a ready-made jewelry piece where the stones are already selected. But, as you’ll learn, we do not recommend that. Here’s why.

If you have read any of our other reviews and particularly our diamond education articles and guides, you’ll know that the most critical aspect of any diamond is the diamond cut (especially for brilliant cut diamonds). Therefore, you should never compromise on cut quality and always pick the highest. It’s as simple as that.

However, many diamond sellers do not use the best diamond cut when choosing diamonds for pre-set jewelry (a notable exception is Ritani). Many jewelers handily omit the diamond cut grade when listing the other 4Cs of the pre-set jewelry. You will therefore have to ask their support to tell you. Is Grown Brilliance an exception?

We’re pleased to report that Grown Brilliance now lists the cut grade on almost all jewelry, which is an improvement over what we saw in our last review of Grown Brilliance. In addition, we appreciate the transparency, which many other jewelers could learn from!

Pre-Set Diamond Cut Quality - Grown Brilliance Review

A few jewelry pieces do not come with a listed diamond cut grade. Typically, this is when the diamonds are small, such as in the below example. Usually, small diamonds and accent stones are not graded. At Grown Brilliance, any diamonds in pre-set jewelry below 0.7 carats are not graded independently. That’s a shame, but as you’ll learn next in our review of Grown Brilliance, it probably won’t be relevant anyway.

Pre-Set Diamond Cut Quality Missing - Grown Brilliance Review

Diamonds used in ready-to-ship jewelry that are graded (by themselves or by IGI) all have a minimum diamond cut grade of at least excellent. The website has not yet been updated to reflect the lower minimum grade yet, but this is a great improvement since you want to avoid the “very good” diamond cut grade that most diamond jewelers offer. So, compared to other diamond jewelers, the quality of diamonds at Grown Brilliance is much better!

Do remember that IGI grades most lab diamonds (see more below), and their best cut grade is ideal. For that reason, we generally advise you to pick your own diamonds from their loose diamond inventory, as we also teach you in our guide to buying the perfect lab-grown diamond. Remember, the best cut grade for most lab-grown diamonds is ideal.

In some cases, you could also get a diamond with an ideal cut grade, and Grown Brilliance has assured us that they use the best possible diamonds available at the time of production. If that is the case, we would be more inclined to recommend their pre-set diamond pairings, but, in general, we would still advise that you pick a diamond yourself.

And luckily, you have the option to pick your own diamond from the loose diamond inventory, as we mentioned earlier in this Grown Brilliance review. So don’t despair – just avoid the pre-set, ready-to-ship jewelry, reach out to the friendly Grown Brilliance customer service, and get the exact diamond you want.

So while it’s a shame that Grown Brilliance doesn’t always use the best quality diamonds for their pre-set jewelry, they are very flexible with custom creations, and you can pick any loose diamond to match with jewelry on their site.

To boot, Grown Brilliance boasts an excellent inventory of loose diamonds and one of the biggest and best inventories of diamond jewelry designs. While on the website, you’re only able to customize rings with your own choice of diamond, you can just contact customer support to have them create a piece with the diamonds of choice. That is one reason Grown Brilliance is one of our best-rated places to buy lab-grown diamond jewelry!

Grown Brilliance’s unique diamond jewelry designs

One thing that sets Grown Brilliance apart from many competitors, such as Clean Origin and Brilliant Earth, is its unique design collections. These include collaborations with the well-known designer Badgley Mischka, who is probably most famous for designing sparkly shoes (so it’s a fitting collab).

The extensive inventory of unique designs is something we’ve seen most notably in our review of Vrai. However, unlike Vrai, Grown Brilliance uses better quality diamonds and, very importantly, independently graded diamonds.

In addition, Grown Brilliance offers one of the largest inventories of jewelry designs, which includes all possible variations from classic jewelry, such as tennis bracelets, to fashion jewelry and, as mentioned, unique designer collaborations.

Lastly, Grown Brilliance presents its jewelry pieces and designs in high-quality and accessible images and videos, brilliantly showcasing the beauty of the diamonds and jewelry.

Grown Brilliance presentation of jewelry designs

We’re very impressed by how Grown Brilliance combines high-quality diamonds and stunning jewelry designs and recommend Grown Brilliance over other places, such as Vrai or Best Brilliance, with a similar focus on unique jewelry designs.

Grown Brilliance lab-grown diamond certification

All Grown Brilliance diamonds are certified by IGI (the leading lab-grown diamond grading institute). So you can trust that you are buying a legit diamond. And as we’ll note in the next section of the Grown Brilliance review, they are working on making access to the certificates readily available online.

Grown Brilliance diamond buying process and inspection

This part of our Grown Brilliance review examines the buying experience on their website, from finding suitable diamonds to inspecting diamond quality over customer support and service.

Starting with the online shopping process, our previous review of Grown Brilliance found it was a breeze and similar to the better online diamond jewelers. But with recent improvements, the shopping experience is now on par with the best places to shop lab-grown diamonds (which is why they’re now included in our list).

As with the other top-rated online diamond sellers, the buying process is straightforward and easy to navigate. You either pick a ready-to-ship jewelry piece or start by finding a loose diamond. As we noted above in our Grown Brilliance review, we recommend that you find a diamond yourself among their loose diamonds and pair it with whatever jewelry you are looking to buy. This way, you’ll end up with a much better diamond.

Thus, in this part of the Grown Brilliance review, we’ll focus on the experience of picking your diamonds and creating your own jewelry.

The first step is to narrow your diamond search to suitable stones with the grades that match your needs (learn how in our lab-grown diamond buying guide). This is exactly what we did in the Grown Brilliance review when we looked at their inventory of our reference stone. You would do the same with the diamond dimensions you are looking for.

Once you have a shortlist of suitable diamonds, you’ll start to examine them more closely and compare them. That’s what we refer to as the diamond inspection process.

Grown Brilliance diamond inspection

In this part of the Grown Brilliance review, we’ll look closer at the diamond inspection features on their website. This is a critical part of buying and probably one of the most challenging. Therefore, you must have access to the right features and information.

The first thing you’ll see when landing on the diamond details page is an image of the stone. This is usually an enlarged image allowing you to see any visible imperfections and symmetry.

The diamond image quality at Grown Brilliance is excellent and adequate to look for any impurities or imperfections related to diamond clarity. As can be seen in the example below, there are visible imperfections. In some cases, that can be acceptable, but you must be able to inspect them and get a sense of whether they detract from the diamond’s brilliance (ability to reflect light).

Grown Brilliance Review (2022) - What You Need to Know Before Buying | grown brilliance review diamond inspection image quality

In addition to the enlarged image, Grown Brilliance offers 360-degree video of most of its diamonds. This allows you to thoroughly inspect the diamond from all angles, look for any inclusions or blemishes, color tint, and evaluate the brilliance (sparkle). Generally speaking, the diamond should be “eye-clean,” meaning that you should not be able to see any notable issues with light reflections when looking at the 360-degree video material.

Grown Brilliance 360-degree diamond image

The video quality at Grown Brilliance (when available) is fantastic. It’s among the best we’ve seen, and you can move around the diamond as you please. However, some previous features have been removed, such as flipping the image. We hope to see them reintroduced, though you can probably do without them.

Grown Brilliance now has 360-degree videos of almost all diamonds (before, it was limited to diamonds with a weight of around 1.3-carat and above). Grown Brilliance continues to add more 360-degree images of smaller diamonds, and it’s rare that 360-degree video is not available. That’s outstanding and allows you to clearly study any prospective diamonds. Few other lab-grown diamond sellers offer the same.

Another critical element of the diamond inspection is the diamond certificate. Here, you’ll be able to see where any inclusions and blemishes might be located, guiding your image and video analysis. In the certificate and on the details page, you can also assess the dimensions of the diamond in more detail.

Grown Brilliance used to give you instant access to the diamond certificate. However, this is no longer the case. Instead, you are prompted to contact their customer support. While they will gladly send it to you, it does impact the ability to compare and assess the diamonds you are considering quickly. A plus is that the certificate you can get is not a tiny version like GemsNY has or a homemade certificate like Vrai’s.

In summary, the diamond inspection features are excellent, and particularly the image and the 360-degree high-quality video are big plusses. They allow you to do your due diligence before deciding on the exact diamond that you want for your jewelry. If only the diamond certificates were available, the inspection features would be on par with Ritani and Clean Origin and nearly as good as James Allen. However, we have been told they should be available online later, which would be fantastic.

Grown Brilliance ring designer

Another key differentiator for Grown Brilliance is its ring designer. When you have decided on the perfect diamond, you can then choose to see it set in the ring of your choice. And the great part is that you can easily see it set in endless ring types, colors, etc.

Grown Brilliance ring designer

As seen above, you can rotate the ring however you like to inspect the details and the ring from any angle. This is really impressive and better than what we have seen at competing diamond jewelers. Our only wish is that you could design and customize other types of jewelry, but that may come in the future.

Having this feature significantly reduces the uncertainty about buying online. Coupled with the generous return policies of Grown Brilliance, there is no reason to go to a physical store. And while With Clarity’s home preview is excellent, you get almost as good an impression with Grown Brilliance 3D ring designer.

In fact, we believe that with the combination of Grown Brilliance’s leading ring designer, their endless customization options, and a vast selection of classic and unique ring designs, Grown Brilliance is the best place to buy lab-grown diamond engagement rings!

Grown Brilliance customer support and service

In this section of our Grown Brilliance review, we’ll examine its customer service, the support channels, and how knowledgeable they are and can guide you to find the perfect diamond.

We have thoroughly tested all customer service channels and have found that, in general, Grown Brilliance offers excellent customer service. While their chat service is not 24/7 (and closed on weekends), they were very responsive when available (within less than a minute) and got back to us at their earliest convenience when unavailable.

Their support is very friendly and happy to help with all your questions and guide you through the buying process. Unlike what we recently experienced in our review of, their support is not pushy and focuses on the questions asked and your needs.

In addition to reading our guides to finding suitable diamonds, you may also want to consult with the seller’s advisors. Some diamond jewelers, like James Allen, Ritani, and Clean Origin, offer trained gemologist support through virtual appointments and chat functions (James Allen wins for the best inspection features).

And now, Grown Brilliance too offers these premium features. A key additional service that Grown Brilliance has added is virtual consultations. You can easily book an appointment using their online booking system, and it’s easy to find a time.

It's easy to book and find time for virtual appointments at Grown Brilliance, as we find in our Grown Brilliance review.

Another new addition to Grown Brilliance’s services is the opening of their very first physical store. It’s located in Manhattan, NY, along the prestigious shopping area of 5th avenue. They’re accepting physical appointments starting November 1st, 2022, and it’s a great addition to their already excellent customer care channels. The addition of a physical location also adds to the trustworthiness of Grown Brilliance.

It's easy to book and find time for physical appointments at the Grown Brilliance showroom, as we find in our Grown Brilliance review.

Grown Brilliance lab-grown diamond prices

When evaluating prices in our Grown Brilliance review, we first examine the cost of loose diamonds. These are easier to compare, like for like, though even that is challenging since no diamond is the same. So what we do instead is to compare the overall price levels for good quality diamonds within specific popular ranges, such as our reference diamond.

Overall, the prices at Grown Brilliance are very competitive and close to the price leaders Clean Origin, Brilliant Earth, and Ritani, and usually better than what you’ll find at James Allen.

The inventory of our reference diamond was minimal so it’s harder for us to compare, but, as you can also read in our overview of the prices for a 1-carat lab-grown diamonds, Grown Brilliance is typically on the lower end of the spectrum with diamonds ranging around $1,000 for diamonds with slightly higher colors grades that our reference diamond. Larger diamonds similarly run close to the prices of price-leading Clean Origin and Ritani.

Grown Brilliance also sells pre-set jewelry, such as earring studs and tennis bracelets, but prices are more difficult to compare since sellers tend not to match those with the best or even similar diamonds. Generally, prices tend to run higher than Clean Origin, but Grown Brilliance pairs its jewelry with higher-quality diamonds.

As noted, customer service several times told us that the diamond cut quality was excellent to ideal. So if you find ready-to-ship diamond jewelry set with ideal-graded diamonds, we would not hesitate to recommend them (of course, always make sure you can return jewelry if you’re not satisfied – more on that below in our Grown Brilliance review).

One area where Grown Brilliance stands out is its guarantee that you won’t find the product you purchase to go on sale later. But, of course, part of the promise is that their prices are already rock bottom, which we can confirm (this is similar to Clean Origin).

Shop confidently knowing that our diamonds and jewelry are priced right year-round, without ever going on sale.

Grown Briliance

We like that from a consumer standpoint since you don’t need to wait around for something to go on sale and won’t get buyer’s remorse seeing what you bought being marketed at a discount. That said, Grown Brilliance offers complimentary gifts, similar to what Brilliant Earth sometimes does.

So we recommend signing up for our newsletter to be alerted of combination deals at Grown Brilliance (see also our list of ongoing diamond sales and Black Friday deals or holiday sales).

In conclusion, we find that the prices at Grown Brilliance are highly competitive, and you should be able to get an excellent deal at Grown Brilliance. While we don’t recommend that you buy pre-set jewelry set with diamonds with less than the best diamond cut, you can pick a loose diamond and pair it yourself. So either create your own jewelry by choosing your own diamonds or, if that’s not possible, reach out to customer service and ask if they can set you up with a better stone.

Grow Brilliance Diamond shipping and returns

The last part of our Grown Brilliance review assesses their shipping and return policies.

Grown Brilliance has free shipping on all orders, as you should expect. They ship with FedEx 2Day delivery, fully insured, so you don’t have to worry about lost parcels. Note that this may vary if you shop at Amazon.

You can pay extra for overnight shipping and Saturday delivery, which others like James Allen and Clean Origin offer for free. We think Grown Brilliance should do the same, but 2-day delivery will be satisfactory in most cases. At least you don’t have to pay for shipping like with Zales.

Returns are also free; you have fully 45 days to return your (unworn) jewelry. Simply contact their customer service, and they’ll send you a return label. That’s pretty gracious and better than most places where the standard is 30 days. Of course, it’s not up there with Clean Origin’s 100-day return period, but it’s still excellent and better than what James Allen, Brilliant Earth, and Ritani give you.

Grown Brilliance Review Verdict

Throughout our Grown Brilliance review, we have been positively surprised. Compared to our previous review of Grown Brilliance, which was also very positive, we have seen a lot of additional new features propelling Grown Brilliance onto the list of the best places to buy lab-grown diamonds.

Grown Brilliance stands out with its unique ring design tools and unparalleled inventory of diamond jewelry designs, from designer collaborations to endless variations over classic diamond jewelry pieces.

Grown Brilliance is dedicated to sustainability, nearly at the level of Brilliant Earth and Vrai. All boxes are made from recycled materials, and some jewelry designs are made from recycled materials. We wish they offered sustainable-graded lab diamonds, but that may come.

We appreciate their dedication to lab-grown diamonds and that they are strong advocates of the benefits that lab-created diamonds bring to the environment and society over mined diamonds. Expanding access to lab-grown diamonds to new buying platforms such as Amazon, like Friendly Diamonds, Best Brilliance, and New World Diamonds is also a plus.

The shopping experience and ability to assess diamonds are just as good as those at Clean Origin and Ritani. The only missing thing is direct access to diamond certificates, which is a critical component when comparing diamonds. However, unlike Vrai or Lightbox Jewelry, the diamonds at Grown Brilliance are graded by reputable institutes like IGI.

Like most diamond jewelers, ready-to-ship diamond jewelry is not (always) set with the highest-quality diamonds, but it’s better than what most competitors offer with a minimum cut grade of excellent.

However, that should not matter since you can pick any diamond in their vast inventory and pair it with the jewelry of your choice. And we always recommend you do that. And it’s easy, too, even if you can (yet) only use their superior designer for rings.

The selection of loose diamonds is smaller than what we have found at Clean Origin, Brilliant Earth, and Ritani (and the inventory of fancy-colored diamonds at New World Diamonds). But it’s still usually large enough for you to be able to find suitable diamonds. Again, it’s similar to what we have seen at Vrai and Friendly Diamonds.

The inventory of loose diamonds skews a little to higher-quality color grades, similar to James Allen, where we prefer a more comprehensive inventory (and sometimes recommend lower diamond color grades).

Prices are very competitive, too, and comparable with Clean Origin and Ritani, even if the smaller inventory makes it harder to compare. So while there are no diamond and jewelry sales, prices are already so low that you’ll get a fantastic deal (Clean Origin is the same).

With the addition of virtual appointments and now also a physical showroom in New York City, Grown Brilliance has graduated to the level of our top-rated diamond jewelers Ritani, Clean Origin, James Allen, and Brilliant Earth.

Their return policy is among the very best, with 45 days of risk-free shopping, and shipping is free, as it should be, though it would be nice to see complimentary expedited shipping. Still, it’s much better than most other places like Helzberg and Zales and not confusing as the case is with

Earlier, we compared Grown Brilliance to other online jewelers focused on selling through marketplaces such as Amazon, namely Friendly Diamonds, Best Brilliance, and New World Diamonds. However, it’s clear that Grown Brilliance is in another league and is now among the best places to buy lab-created diamonds.

All in all, we highly recommend Grown Brilliance and find that they are among the best places to buy lab-created diamonds and jewelry online!

We land on a very impressive 4.7 out of 5 stars!
