We have updated our Grown Brilliance review for 2026 to reflect the many recent updates to their website, 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.

Our Bottom Line Verdict

Category	Our Assessment (2026)
Overall Rating	★★★★☆ (4.5 / 5)
Best For	Sustainable jewelry lovers who prefer premium-grade diamonds
Price Range	$$–$$$ (Higher due to D–F color and Excellent–Ideal cut only)
Pros	Beautiful designs, strong sustainability values, intuitive website, superior diamond inspection features.
Cons	Smaller diamond inventory, only D–F color diamonds, 30-day return (previously 45), no free overnight shipping
Our Take	Grown Brilliance continues to deliver on quality and sustainability, but the limited selection and higher prices make it less ideal for budget-conscious buyers.
Our 2026 Recommendation	💎 We recommend James Allen or Ritani for a larger diamond selection, better prices, and top-rated customer service.

Our updated Grown Brilliance review (2026) finds that they continue to impress with their excellent craftsmanship, strong sustainability values, and beautiful collection of designer jewelry. Their website experience is among the most intuitive in the industry, which makes it easy for customers to browse and customize pieces.

That said, the company has made some trade-offs in the past year. Their loose diamond inventory is now smaller, and value-conscious shoppers can no longer find lower-grade stones that offer great sparkle at more affordable prices. Likewise, pricing is on the higher end compared to competitors like Ritani or James Allen.

In short, Grown Brilliance is still a top choice for those who value thoughtful design and sustainability — just expect to pay a little more for it.

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 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. To compete with leading lab diamond sellers such as James Allen, Ritani, and Brilliant Earth, Grown Brilliance has significantly revamped and greatly expanded the services and features on their site.

Though Grown Brilliance is a relatively new lab diamond jeweler, 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.

Sustainable Lab-Grown Diamonds

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.

Similar to competitors like Brilliant Earth and Vrai, they go out of their way to be as sustainable as possible. They focus exclusively on selling lab-grown diamonds, which are the sustainable and environmentally friendly diamond choice. Grown Brilliance takes it a step further by purchasing carbon credits to help reduce its carbon footprint, using recycled gold in its products, and employing sustainable packaging made entirely from biodegradable materials.

Recycled Packagning

Over the years, we’ve reviewed numerous brands, and one area that often gets overlooked is packaging. The jewelry boxes from Grown Brilliance immediately stood out to us. They’re beautifully designed, sturdy, and give a genuinely high-end feel — the kind of packaging you’d expect from a luxury jeweler. Beyond aesthetics, we appreciate that the boxes are made entirely from recycled materials, aligning with the brand’s sustainability mission. It’s a small detail, but it emphasizes Grown Brilliance’s commitment to providing an elevated experience from the moment you open the box.

We loved unboxing our Grown Brilliance jewelry — the packaging feels elegant and high-end.

Lab Diamond Selection

As we’ve mentioned before, 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.

Lab Diamond Inventory and Quality

At the time of this review, Grown Brilliance offers around 160,000 loose lab-grown diamonds. In earlier years, their diamond inventory was significantly larger (just a year ago, Grown Brilliance had well over 250,000 loose lab diamonds), and it included a broader range of quality grades. In comparison, retailer Ritani currently lists access to more than 500,000 loose lab diamonds, giving them one of the largest online inventories in the industry.

Premium Lab Diamonds

Grown Brilliance has shifted its focus to exclusively offer high-quality diamonds, phasing out options with lower clarity, cut, and color grades. Last year, shoppers could find diamonds with a G color grade, but now the selection is limited to only those with D to F color grades, which are more expensive.

This change means Grown Brilliance’s inventory now skews towards higher color grades than we typically recommend for value-conscious buyers. However, that’s not necessarily a bad thing; it depends on your preferences. For example, when it comes to engagement rings, it’s common to aim for a slightly higher color grade.

Expert Tip:
While D–F color diamonds appear exceptionally bright and white, they also come with a noticeable price premium that’s not necessaily worth the cost. For most engagement rings, a G–H color diamond offers the same sparkle and visual appeal at a significantly lower price. And when paired with a yellow or rose gold setting, you won’t be able to see the difference. The key is to prioritize cut quality first, since that has the biggest impact on brilliance.

Grown Brilliance showcases a vast inventory of over 160,000 loose lab-grown diamonds. Allowing you to:

• Choose from 1 to 16 carats
• Quick Ship’ diamonds: These are typically ready to dispatch within 1-2 days (excluding the time needed to craft the ring).
• Classic shapes: Options such as round, oval, cushion, princess, and emerald.
• Cut grade: Ranging from excellent to ideal.
• Color grades: Available from D to F.
• Clarity grades: From VS2 to IF.

As shown in the screenshot below, Grown Brilliance previously offered a much larger diamond inventory, including options with G color grades, before narrowing its focus to higher-quality stones.

Diamond Prices

Grown Brilliance offers competitive pricing on lab-grown diamonds, with a 1-carat, round-cut, VVS2, Ideal cut, D-G color diamond priced just under $1,000. In fact, we found more than 2,000 loose lab diamonds that matched those criteria.

That said, most of their lab-grown diamonds are of superb quality, and you still have a good chance of finding a suitable diamond at Grown Brilliance.

However, for the best deals, Ritani (as always) outperforms, offering 1-carat, round-cut, VVS2, Ideal cut, D-G color lab diamonds at under $400! That’s less than half of what you’ll typically pay at Grown Brilliance for a comparable stone.

Ready-to-Ship 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, most 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.

Pick Your Preferred Diamond Quality

Is Grown Brilliance an exception? Yes, and even better, Grown Brilliance now lets you choose the overall diamond quality for many of their ready-made jewelry pieces. You can select between “Good,” “Better,” and “Best,” depending on your budget and what matters most to you—whether it’s size, clarity, or overall brilliance. We really like this level of transparency and flexibility because it makes it clear what you’re paying for and ensures you get exactly what you expect. Few jewelers make it this easy to tailor your jewelry piece like that, and it’s another example of how Grown Brilliance continues to evolve and improve their shopping experience.

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.

We’re honestly 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.

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.

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).

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. Unfortunately, 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.

We have been told they should be available online later, which would be a significant improvement. Unfortunately, nearly two years have passed since those initial assurances, and this feature still hasn’t been implemented. It’s a bit disappointing, especially since competitors like Ritani and James Allen allow instant access to diamond certificates directly from the product page. We hope Grown Brilliance will follow through soon, as it’s one of the last missing pieces in an otherwise excellent online buying experience.

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 nearly as good as James Allen.

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.

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.

Customer Support and Service

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.

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.

Grown Brilliance Showrooms

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 2026, Grown Brilliance now has 14 locations in the US.

Shipping and Returns

• Grown Brilliance has free domestic shipping on all orders. They ship with FedEx 2Day delivery and are fully insured, so you don’t have to worry about lost parcels.
• Overnight shipping and Saturday delivery available at an extra cost.
• Free 30 day returns for unworn jewelry. Contact their customer service online, and they’ll send you a return label. Returning our purchase was easy, and our refund was issued quickly.

Returns are straightforward and processed quickly. You can pay extra for overnight shipping and Saturday delivery, which competitors like James Allen 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.

Summary of Our 2026 Grown Brilliance Review

Strong Design Tools and Distinctive Jewelry

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. Their website is intuitive and user-friendly, and we appreciate the brand’s focus on sustainability and high-end craftsmanship.

Smaller Diamond Inventory and Higher Prices

However, we were somewhat disappointed by the reduced loose diamond inventory. Compared to previous years, Grown Brilliance now offers fewer loose diamonds and focuses on D–F color and Excellent–Ideal cuts. While this ensures high quality, it limits flexibility for budget-conscious buyers.

We often recommend exploring slightly lower color grades (like G or H) to save money without sacrificing sparkle, but those options are no longer available here.

Value Compared to Ritani and Other Competitors

When compared to competitors such as Ritani, Grown Brilliance’s prices for similar stones are often significantly higher, sometimes by several hundred dollars per carat. This means that shoppers who prioritize price may find better deals elsewhere.

In short, you pay more for presentation and sustainability, but not necessarily for better diamond value.

Excellent Craftsmanship but Missing Key Features

Nevertheless, we still love the quality of Grown Brilliance’s craftsmanship, beautiful jewelry packaging, distinctive designs, and their ready-to-ship jewelry options, which let you choose between “Good,” “Better,” and “Best” diamond categories.

That said, it’s disappointing that they still don’t offer direct access to diamond certificates, a critical feature when comparing diamonds.

Premium Feel at a Premium Price

Grown Brilliance positions itself as a premium choice, emphasizing sustainability, artistry, and presentation over sheer price competition. Their products look and feel luxurious from eco-friendly packaging to meticulously curated designs, but you do pay a premium for these touches.

If saving the most money is your top priority, competitors like Ritani still hold the edge thanks to their broader diamond inventory and lower prices for equivalent specs. However, for those who appreciate an elevated shopping experience, high design standards, and the assurance of sustainably created diamonds, Grown Brilliance remains an appealing option.

In other words, you pay a premium for presentation and sustainability, but for pure value, Ritani remains the better choice.
