Summary of Our Grown Brilliance Review
The prices at Grown Brilliance are still very competitive. As you can see from our lab diamond price analysis, Grown Brilliance offers the lowest prices for 1.5-carat lab diamonds. 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 the buying process to be effortless and full of great options. But, we do miss a few key features.
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. Production and shipping can also be slower.
If you prefer to research on your own, which we recommend, 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.
One key area where Grown Brilliance stands out is its extensive selection of fine jewelry and exclusive designs. These include the exclusive collaboration with designer Badgley Mischka and the recently launched High Jewelry collection. These collaborations align Grown Brilliance closer to brands such as Vrai, Pandora Brilliance, and Kimaï. But, importantly, 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 2023!
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.
Our Bottom Line Grown Brilliance Reviews Verdict:
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 4.7 out of 5 stars. 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 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 was born an Amazon-first brand but has matured into a fully-fledged online diamond jeweler. This includes offering many of the premium features that leading established jewelers do.
Grown Brilliance started out focusing on selling through platforms such as Amazon but now focuses on selling through its own website. The site is now their main point of sale and offers fantastic customer service and support.
This includes Grown Brilliance revamping and greatly expanding the services and features on their site. Now, they are competing with leading lab diamond sellers such as James Allen, Clean Origin, Ritani, and Brilliant Earth.
Grown Brilliance is a relatively new lab diamond jeweler. However, the key team behind the brand all have years of expertise in the diamond business and the luxury product industry. This includes Zales, Tag Heuer, and similar companies. Their combined experiences have allowed them to build and scale Grown Brilliance at an impressive pace and develop the brand into the renowned jewelry brand it is today.
Who founded Grown Brilliance?
Grown Brilliance was founded by Akshie Jhaver, a third-generation jeweler. She is also the creative director and behind many of the incredible designs that Grown Brilliance offers. Grown Brilliance is owned by a group of investors who have formed the holding company AJS Creations LLC.
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. It 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. 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.
All diamonds sold at Grown Brilliance are certified by IGI, GIA, or GCAL. These are the leading diamond grading institutes, so you can trust the diamond certification. Note that small accent stones are generally not certified.
Grown Brilliance offers one free resizing of rings up to 30 days after you buy your ring. Send the ring to Grown Brilliance, and they’ll return it after it’s been resized. Note that it is for US orders only.
Grown Brilliance started out online only but opened its first retail store on 5th Ave. in Manhattan, NY, in 2022. Grown Brilliance has since opened three more locations in Texas, Florida, and Pennsylvania. You can set up appointments to visit them at their retail store on their website. Grown Brilliance still primarily sells through its own website, grownbrilliance.com, 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.
Grown Brilliance opened its first retail store where you can book appointments in Manhattan, New York. The address for Grown Brilliance is 521 5th Avenue, Suite 820, New York, NY 10175. They have since expanded to Houston, Philadelphia, and Boca Raton. 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. They 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.

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. But 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 LabGrownCarats.com.
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, we’ll see how their focus on lab-grown diamonds translates into their diamond selection.
Huge 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 or set in jewelry. The loose diamonds can be used to create your own jewelry.
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.
Loose Diamond Inventory
At the time of the review, Grown Brilliance has almost 92,000 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 and Brilliance.com have in store (or at least access to). But it’s more than most other leading online diamond jewelers.
Diamond Inventory Comparison
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.

Narrowing our search to these criteria, surprisingly, we found 28 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. Our Brilliance.com review found a lot too, but these are based on broad wholesale lists.
But, Grown Brilliance starts its color grades at I and does not carry any J-graded diamonds. This is similar to James Allen and a few other jewelers, who focus on higher color grades. If we instead include the H-grade, the number of diamonds increases to 54.

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, as 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. That fits well with Grown Brilliance’s top stop as our #1 place for lab-grown diamond engagement rings.

We typically find that you can save by lowering the color grade, as we detail in our guide to lab-grown diamond colors. Later, we’ll look at the prices of both the reference diamond and the higher color-graded diamonds.
The inventory at Grown Brilliance is bigger than what we saw at Friendly Diamonds and similar to the diamond inventory at Vrai. While it’s slightly smaller than at James Allen, it’s still very good. Notably, the diamonds we found were all of outstanding quality, and most were eye-clean (with no discernable inclusions or color issues).
The selection is thus a little smaller than other sellers, but most of their lab-grown diamonds are of superb quality. You should thus still have a very good chance of finding a suitable diamond at Grown Brilliance. In combination with the low diamond prices, this is a compelling offer. We’ll get into the diamond prices a little later in our review.
Pre-Set 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.
In our other reviews, diamond education articles, and guides, we highlight diamond cut as the most critical aspect of diamonds. In short, 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 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!

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.

Diamonds used in ready-to-ship jewelry that are graded all have a minimum diamond cut grade of at least excellent. The website has not yet been updated to reflect the lower minimum grade, 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. Remember, the best cut grade for most lab-grown diamonds is ideal. You can learn more in our guide to buying the perfect lab-grown diamond
In some cases, you could also get a diamond with an ideal cut grade. 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.
Jewelry Customization
Luckily, you have the option to pick your own diamond from the loose diamond inventory, as we noted. 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.
It’s a shame that Grown Brilliance doesn’t always use the best quality diamonds for their pre-set jewelry. But they are very flexible with custom creations, and you can pick any loose diamond to match with jewelry.
To boot, Grown Brilliance boasts an excellent inventory of loose diamonds and one of the biggest and best inventories of diamond jewelry designs. On the website, you’re only able to customize rings with your own choice of diamond. But you can just contact customer support to have them create a piece with the diamonds of your choice. That is one reason Grown Brilliance is one of our best-rated places to buy lab-grown diamond jewelry!

Unique Jewelry Designs
One thing that sets Grown Brilliance apart from many competitors 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. This 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.
We’re very impressed by how Grown Brilliance combines high-quality diamonds and stunning jewelry designs. That’s why we recommend Grown Brilliance over other places, such as Vrai or Best Brilliance, with a similar focus on unique jewelry designs.


High Jewelry Collection
Grown Brilliance recently launched its High Jewelry collection. This is a collection of very high-end and, most often, high-carat lab-grown diamond jewelry. Grouped into Fine Jewelry and Bridal/Engagement, you’ll find a wide range of unique and exquisite designs. The designs are one-off and in very limited supply, and the collection is constantly updated.
The diamond jewelry pieces start at 8 carats and go all the way to 150+ carats, with prices ranging from $10,000 to $200,000+. Clearly, this is not your everyday lab diamond jewelry collection. Compare them instead to what the uber-rich may buy and what you see on the red carpet. But, because the diamonds are lab-grown, prices are a fraction of what you would pay for similar high-end jewelry set with mined diamonds.
See, for example, this stunning 93-carat lab-grown diamond Hilo Necklace from the Grown Brilliance High Jewelry collection.
Learn more in our Grown Brilliance High Jewelry review.

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.
Our Diamond and Jewelry Shopping Experiences
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.
Our earlier editions of our Grown Brilliance reviews found shopping on their website was a breeze. And, 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, 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 grades that match your needs. This is exactly what we did earlier 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.
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.
Diamond Image Quality
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).

In addition to the enlarged image, Grown Brilliance offers 360-degree video of most of its diamonds. This allows you to inspect the diamond from all angles thoroughly. Look for any inclusions or blemishes, color tint, and evaluate the brilliance (sparkle).
Generally speaking, the diamond should be “eye-clean”. That means you should not be able to see any notable issues with light reflections when looking at the 360-degree video material.
Diamond Video Quality
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 study any prospective diamonds clearly. Few other lab-grown diamond sellers offer the same.
Diamond Certificates
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 previously gave instant access to the diamond certificate. However, this is no longer the case. Instead, you are prompted to contact their customer support. They will gladly send it to you, but it does impact the ability to compare and assess the diamonds you are considering. A plus is that the certificate you can get is not a tiny version like GemsNY has or a homemade certificate like Vrai’s.
Diamond Inspection Summary
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.
Ring Designer and Customization
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.
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. Compared to With Clarity’s excellent home preview, you can 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!
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. The chat service is not open 24/7 (and is closed on weekends). But they were very responsive when available (within less than a minute) and got back to us quickly 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 Brilliance.com, 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.
Virtual and Store Appointments
And now, Grown Brilliance also 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.

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, and it’s a great addition to their already excellent customer care channels. In 2023, Grown Brilliance expanded to three more locations in Florida, Texas, and Pennsylvania. The addition of physical locations also adds to the trustworthiness of Grown Brilliance.

Diamond Prices at Grown Brilliance
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. For this, we often use a 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 small, so it’s harder for us to compare. But, as you can read in our list of 1-carat lab-grown diamond prices, Grown Brilliance is very cheap. Typically on the cheapest end, with diamonds ranging around $800 for diamonds with slightly higher color grades than 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. Of course, part of the promise is that their prices are already rock bottom, which we can confirm. Clean Origin has a similar policy.
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. This way, you avoid getting buyer’s remorse when seeing what you bought being marketed at a discount. That said, Grown Brilliance offers complimentary gifts, similar to what Brilliant Earth sometimes does.
We recommend that you sign up for our newsletter to get deal alerts from 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. We don’t recommend that you buy pre-set jewelry paired with lower-quality diamonds. But 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.
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, and you have 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.
Our Pros and Cons of Grown Brilliance
Before we sum up our expert Grown Brilliance review, we list the key benefits and drawbacks that we have found.
Pros
- Low and extremely competitive lab diamond prices.
- The best ring design tool on the market.
- 45-day return period.
- You can customize all jewelry with any loose diamond.
- Dedicated to social and environmental sustainability.
Cons
- No direct access to certificates (but can be requested).
- The designer tool is limited to rings (but see their Truly Custom collection).
- Pre-set diamond cut grade is, in a few cases, only Very Good.
- Delivery, in some cases, can be slow or delayed.
Our Final 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. They are strong advocates of the environmental and ethical benefits compared to 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, reputable institutes like IGI grades the diamonds at Grown Brilliance.
Like most diamond jewelers, ready-to-ship diamond jewelry is not (always) matched with the highest-quality diamonds. But with a minimum cut grade of excellent, the quality is better than at most competitors.
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 smaller than 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. 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.
With the addition of virtual appointments and several stores, Grown Brilliance has graduated to the level of our top-rated diamond jewelers Ritani, Clean Origin, James Allen, and Brilliant Earth.
With 45 days of risk-free shopping and free shipping, Grown Brilliance is among the best. But it would be nice to see complimentary expedited shipping. Still, it’s much better than most other places like Helzberg and Zales and not as confusing as Brilliance.com.
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 land on a very impressive 4.7 out of 5 stars!

We encourage our readers to share their experiences with Grown Brilliance. Read our visitors’ Grown Brilliance customer reviews below and share your own thoughts above.
Love the design
I purchased a Badgley Mischa (?) diamond ring from Grown Brilliance. It is gorgeous and the diamond is huge! It was more expensive than the other rings, but I loved the design.
Beautiful bracelet
I bought a 3 ct tennis bracelet from Grown Brilliance and I’m so happy with it! I think it was around $1500. Very cheap compared to other stores I’ve been to and the quality seems great.
Late but awesome
My order was late and I had to contact customer support twice. But I was not in a hurry since it was a gift for myself. And it was worth the wait. The diamond earrings are so beautiful and sparkly. I don’t know about the quality yet because I bought them recently, but it seems good.
Fake products
Do not buy
Late order
My order has not arrived, I’m still waiting for it.
Grown Brilliance Reviews from Customers

Do not buy a diamond fro Grown Brilliance. Their products are fake and have major flaws.
Thanks for sharing your experience. We have not experienced that any of their products are fake. Diamonds from Grown Brilliance are lab-created but are real diamonds (see https://labgrowncarats.com/are-lab-grown-diamonds-real/), usually certified by IGI or another independent diamond laboratory. Could you share more details about your purchase and experience with Grown Brilliance?
I read on the Grown Brilliance site that the IGI cert is not included and has to be requested, should that be a concern? And, how can the piece be returned if need be, without one?
We have not experienced that, but the IGI certificate should be included. If not, you should contact their customer service and request the certificate. If they don’t provide it, we recommend returning your purchase. However, usually, diamonds from Grown Brilliance come with the certificate.
