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

We have updated our 2024 Grown Brilliance review to reflect the many recent updates that Grown Brilliance has made to its site, diamond offerings, and services. Learn how they stack up to the competition now. And if they have managed to join the ranks for the best places to buy lab-grown diamonds.

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. Their inventory of both loose and pre-set diamond jewelry is impressive, though not as large as, for example, what we saw when reviewing Ritani. Our Grown Brilliance review also finds the buying process 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 independently, 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!

We have rated Grown Brilliance to be the best place to buy lab-grown diamond engagement rings in 2024.

Another area is their unparalleled and market-leading ring design tool. It allows almost endless customizations of any ring and will enable you 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 2024!

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 Verdict

Our Grown Brilliance review finds 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 focusing on selling through platforms such as Amazon but now focuses on selling through its 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, including 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?

Akshie Jhaver, a third-generation jeweler, founded Grown Brilliance. She is also the creative director behind many of the incredible designs offered by Grown Brilliance. 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. 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; you can reach them via 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.

Is Grown Brilliance certified?

All diamonds sold at Grown Brilliance are certified by IGI, GIA, or GCAL. These are the leading diamond grading institutes, so you can trust their certification. Note that small accent stones are generally not certified.

Does Grown Brilliance resize rings?

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.

Does Grown Brilliance have any stores?

Grown Brilliance started 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 online retail store. Grown Brilliance still primarily sells through its website,, and on Amazon. Generally, that means costs are lower, 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 opened its first retail store in Manhattan, New York, where appointments can be booked. The address 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.

Grown Brilliance is dedicated to the better diamond choice of lab-grown diamonds.

In addition to only selling lab-grown diamonds, Grown Brilliance, the sustainable and environmentally friendly diamond choice, 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 site’s expert diamond content, 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. You can read the rest here at

Does Grown Brilliance sell real diamonds?

Grown Brilliance specializes in selling lab-grown diamonds and jewelry. Lab-grown diamonds are 100% real 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. Therefore, Grown Brilliance 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 selection.

Huge Diamond Selection

As our Grown Brilliance review mentioned, Grown Brilliance focuses solely on lab diamonds. It sells lab-grown diamonds as loose stones or set in jewelry. The loose diamonds can be used to create your 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 had over 188,000 loose lab-grown diamonds. That is a decent collection, almost three times more than when we last reviewed Grown Brilliance. Grown Brilliance’s inventory has…grown! It’s still fewer than the 258,000+ that Ritani and 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).

Of course, the cut 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 example.

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 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.

Loose diamond search results at Grown Brilliance review.

We tried expanding our search and performed numerous additional searches to gauge Grown Brilliance’s diamond inventory profile.

We found that, like in our James Allen review, Grown Brilliance’s inventory skews towards higher color grades than 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.

Expanded loose diamond search results.

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

The inventory at Grown Brilliance is more extensive 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 impressive. 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. Thus, you still have a 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 buy ready-made jewelry with the stones 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 the 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!

Pre-Set Diamond Cut Quality.
Grown Brilliance pre-set diamond cut grades range from very good to excellent or ideal. The minimum is usually excellent.

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. Small diamonds and accent stones are usually 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.

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!

Remember that IGI grades most lab diamonds (see more below); their best-cut grade is ideal. Therefore, we generally advise you to pick your 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.

Sometimes, you could also get a diamond with an ideal cut grade. Grown Brilliance has assured us they will use the best diamonds available at production. If so, 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

As we noted, you can pick your diamond from the loose diamond inventory. So don’t despair. Avoid the pre-set, ready-to-ship jewelry, reach out to the friendly Grown Brilliance customer service, and get the 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.

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 can only customize rings with your diamond choice. But you can 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!

For most pre-set diamond jewelry, Grown Brilliance uses Excellent or Ideal cut lab-grown diamonds.

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).

We’ve seen an extensive inventory of unique designs, most notably in our review of Vrai. However, unlike Vrai, Grown Brilliance uses better-quality diamonds, notably independently graded diamonds.

In addition, Grown Brilliance offers one of the largest jewelry design inventories. 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.

Grown Brilliance Review: Pre-set Jewelry

We’re impressed by how Grown Brilliance combines high-quality diamonds with stunning jewelry designs. That’s why we recommend Grown Brilliance over other places, such as Vrai or Best Brilliance, which focus similarly on unique jewelry designs.

High Jewelry Collection

Grown Brilliance recently launched its High Jewelry collection. This collection of very high-end and, most often, high-carat lab-grown diamond jewelry is grouped into Fine Jewelry and Bridal/Engagement. You’ll find many unique and exquisite designs. The designs are one-off, 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+. This is not your everyday lab diamond jewelry collection. Compare them 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.

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 legitimate diamond. 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 noted above, we recommend that you find a diamond among their loose diamonds and pair it with whatever jewelry you want. 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 diamonds and creating jewelry.

The first step is to narrow your diamond search to suitable stones with grades that match your needs. This is precisely 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 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 examine 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 for looking 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 understand whether they detract from the diamond’s brilliance (ability to reflect light).

An example of diamond inspection at Grown Brilliance.

In addition to the enlarged image, Grown Brilliance offers 360-degree videos of most of its diamonds. These videos allow you to inspect the diamond from all angles thoroughly, look for inclusions or blemishes, evaluate the 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 viewing 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, such as flipping the image, have been removed. 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 weighing around 1.3-carat and above. Grown Brilliance continues adding more 360-degree images of smaller diamonds, and rarely, 360-degree video is unavailable. That’s outstanding and allows you to study any prospective diamonds. 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 your 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’s or a homemade certificate like Vrai’s.

Diamond Inspection Summary

In summary, the diamond inspection features are excellent, and, mainly, the image and the 360-degree high-quality video are big plusses. They allow you to do your due diligence before deciding on the diamond 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 see it set in the ring of your choice. And the significant part is that you can easily see it set in endless ring types, colors, etc.

Grown Brilliance Review: Ring Designer
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 impressive and better than 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.

This feature significantly reduces uncertainty about buying online. Coupled with Grown Brilliance’s generous return policies, 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’s 3D ring designer.

With Grown Brilliance’s leading ring designer, 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 and support channels, the knowledge of its employees, and how they can help you 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.

Grown Brilliance can be contacted through chat, email, phone, and in-person or virtual appointments.
Grown Brilliance can be contacted through chat, email, phone, and in-person or virtual appointments.

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.

Virtual and Store Appointments

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 finding a time is easy.

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 2024, 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, we compare the overall price levels for good-quality diamonds within specific popular ranges. For this, we often use a reference diamond.

Overall, Grown Brilliance’s prices are very competitive and close to those of the price leaders Clean Origin, Brilliant Earth, and Ritani. They are also usually better than those 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. It is typically on the cheapest end, with diamonds ranging around $800 for slightly higher color grades than our reference diamond. Larger diamonds similarly run close to price-leading Clean Origin and Ritani prices.

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

As noted, customer service told us that the diamond cut quality was excellent and ideal. So, if you find ready-to-ship diamond jewelry sets with ideal-graded diamonds, we would not hesitate to recommend them. Of course, always ensure you can return jewelry if you’re unsatisfied – 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 for something to go on sale. This way, you avoid buyer’s remorse when you see what you bought being marketed at a discount. That said, Grown Brilliance offers complimentary gifts, similar to what Brilliant Earth sometimes does.

We recommend you sign up for our newsletter to get deal alerts from Grown Brilliance. (See also our list of ongoing diamond sales, 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. 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 jewelry by choosing your diamonds or, if that’s impossible, 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 and are 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 45 days to return your (unworn) jewelry. 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.

  • The best ring design tool on the market.
  • 45-day return period.
  • You can customize all jewelry with any loose diamond.
  • We are dedicated to social and environmental sustainability.


  • 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, which was also very positive, we have seen many 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 on classic 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 strongly advocate for environmental and ethical benefits 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 as good as those at Clean Origin and Ritani. The only thing missing is direct access to diamond certificates, a critical component when comparing diamonds. However, unlike Vrai or Lightbox Jewelry, reputable institutes like IGI grade the diamonds at Grown Brilliance.

Like most diamond jewelers, ready-to-ship jewelry is not (always) matched with the highest-quality diamonds. But with a minimum cut grade of excellent, the quality is better than that of 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 slightly toward higher-quality color grades, similar to James Allen’s. We prefer a more comprehensive inventory and sometimes recommend lower diamond color grades.

Prices are very competitive 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, such as 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 other places like Helzberg and Zales and not as confusing as

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.

Overall, we highly recommend Grown Brilliance and land on a very impressive 4.7 out of 5 stars!

**Subject: Completely Unacceptable Experience with Grown Brilliance**

May 13, 2024

I am compelled to share my extremely disappointing experience with Grown Brilliance, where incompetence and poor customer service have marred what should have been a joyous occasion. In August 2023, my fiancé and I chose Grown Brilliance to purchase our wedding rings. Unfortunately, this decision has led to months of frustration and disappointment.

Shortly after receiving the rings, a diamond fell out. Believing in the integrity of Grown Brilliance, we reached out for a repair rather than contacting our insurance. The company agreed to fix the ring, but this was just the beginning of an ongoing ordeal. Upon receiving the repaired ring, more diamonds fell out not once but repeatedly with each subsequent repair. The quality assurance on these repairs was non-existent, and each resolution attempt only led to further issues, culminating in a ring that didn’t even fit—crafted in the wrong size!

Throughout this process, the customer service was appalling. It took multiple calls to even reach a supervisor, and when I finally did, the response was lackluster. Promises of callbacks went unfulfilled, and when pressed for answers, excuses were made without any real action being taken. I was astounded by the lack of accountability and the casual dismissal of my concerns.

This situation is utterly unacceptable. I am now left with a product that is unusable and a customer service experience that leaves much to be desired. All trust in Grown Brilliance has been eroded, and I am seeking a full refund for the rings that have brought nothing but stress and disappointment to an otherwise joyful occasion.

I urge potential customers to consider this experience as a warning. The lack of professionalism and customer care displayed by Grown Brilliance is not what anyone should have to deal with, especially when it comes to such significant and sentimental purchases.

Happy customer

I bought a pendant necklace at Grown Brilliance for myself and I was very happy with the product. It feels very luxurious and the diamond is just beautiful. I would definitely buy at Grown Brilliance again.


Better than expected!

March 1, 2024

To be honest, I was a bit nervous because there are a few mixed reviews online. I haven’t bought diamond jewelry before online and wasn’t sure what to expect. But I saw an amazing deal on a necklace for Valentine’s and decided to take a chance. It turned out to be even better than I had expected and my girlfriend loved it. It came in a really beautiful box too and looked more expensive than it actually was. Would for sure recommend them based on my experience.

Totally unimpressed.

February 23, 2024

After committing considerable time to making a purchase, I placed my order only to receive an email (not the courtesy of a phone call,) to tell me that my purchase was flagged for potential fraud.

Now, to complete the order, they are requiring that I provide them with a copy of my driver’s license, a copy of my credit card, an additional phone number (who these days has two phones) and an alternative email address.

To top it all off, they gave me 24-hours to respond!

Can you guess what I am going to say, when I reply in about a minute?


Diamond necklace

January 27, 2024

Bought a diamond necklace from Grown Brilliance which is even better than I could have hoped for. Saw a deal here right after I made the purchase and wrote their customer service, who was very helpful and immediately honored it! One thing though, it took a while for the necklace to arrive and I never got a shipping confirmation. Wish the communication had been better and that they would have send some updates about when the package would arrive.

But other than that I would definitely recommend them.

  1. I ordered two rings, I paid for them to be shipped 2 day with Fed X it has been 4 days and I have not gotten them!!!! My husband and I are renewing our wedding vows on Thanksgiving November 24. Please ship it to me asap thank you Theresa STARKEY

  2. 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.


    They promote quality/satisfaction guaranteed but that is a COMPLETE lie!

    I had purchased a tennis bracelet for my girlfriend as an anniversary gift totaling $3800 and it took much longer than expected to receive. (2 months rather than 2 weeks) The worst part…it broke 1 week upon receiving the bracelet. I called them and was told that it would take several weeks more to send in the bracelet and fix it, so I had it repaired locally in under 30 minutes. A couple months later, it broke AGAIN in a different area which assured me that their items are of POOR quality. I called them again to have them right their wrongs and was simply told that I voided their warranty by having it fixed the initial time. I argued that despite getting it fixed elsewhere they had sold me a faulty product. Nonetheless, they had shrugged me off as if I wasn’t a valued customer. You would think that they would try to help out a customer who spent $3800 but no. They do not care. On top of that, I had to call multiple times to get a response back from them.

    This is by far the WORST experience I’ve had with ANY retailer I have purchased from. Writing this review, I am fearful for anyone looking to purchase from this company and I plead with anyone to source another jewelry company to save them from headache. Now I am left with a broken bracelet and a girlfriend who can’t even enjoy the gift that I had saved up tirelessly to get her.

    AGAIN, please please please do not buy from this company. Horrible people, customer service, morals, products, etc. (The list goes on…)
