Updated: November 12, 2025

Brilliance.com is a well-established online jeweler that has been in the diamond business for decades. Customers generally give Brilliance.com excellent reviews, and it’s known for its low prices and excellent customer service. They sell not only mined diamonds but also lab-grown ones, which is why we decided to examine Brilliance.com. In our 2026 Brilliance.com review, we’ll see if they live up to expectations and what you should consider before buying.

Our diamond experts have analyzed and evaluated all aspects of Brilliance.com, from shopping to diamond quality and prices, testing customer service and examining everything from the return policies to the sustainability profile of Brililance.com.

Bottom Line Verdict of Our brilliance.com Review

Our updated 2026 Brilliance.com review finds that Brilliance continues to offer reasonable prices compared to other online diamond jewelers. They also have a large diamond inventory, but not all diamonds are actually available, even when on their site. Brilliance.com has great customer support, making the buying experience easy and user-friendly.

However, we have found that Brilliance.com also has issues, such as:

• Slow order processing and delivery, partly because diamonds are not in stock.
• Diamond jewelry is not graded by independent laboratories.
• Low-quality diamond images and videos.
• Confusing buying terms that are worse than competitors.

All in all, our Brilliance.com review finds that they offer reasonable prices and a decent shopping experience, but with some drawbacks. See our recommended better alternatives below. Our final Brilliance.com review score lands at 3.9 out of 5 stars.

Learn more about what we like and dislike about Brilliance and what you need to know before buying in our in-depth Brilliance.com review.

Who is Brilliance.com?

Jacob Ohayon started Brilliance.com in 1989. He is a GIA-trained and certified gemologist with years of experience in the diamond industry. The company was initially created by importing diamonds to the US and later selling them directly to consumers. Since 2006, Brilliance has been selling diamonds online through its website at Brilliance.com and has morphed into the online diamond jeweler it is today.

Brilliance.com operates out of Boynton Beach, Florida, where it has a showroom, just like Clean Origin, which has a showroom in Texas. However, Brilliance.com has no stores like Brilliant Earth or Vrai. It also doesn’t collaborate with other jewelers like Ritani or James Allen.

Brilliance.com Sells Both Mined and Lab-Grown Diamonds

Brilliance.com has been selling diamonds for decades, long before lab-grown diamonds in gem quality became available at the prices you find today—not long ago, lab-grown diamonds were prohibitively expensive (learn more about the history of lab-grown diamonds).

Therefore, it’s not surprising that Brilliance.com sells mined diamonds. But we’re happy to learn that they are now also selling lab-created diamonds, the ethical choice. This is similar to some of our favorite places to buy lab-grown diamonds, such as Ritani and James Allen.

Sometimes, we find that jewelers who sell mined diamonds tend to focus more on those, while lab-grown diamonds are a secondary option. We also often find that jewelers will not be forthcoming about the many benefits of lab-grown diamonds over mined ones to avoid off-putting mined diamond customers.

Lab-Grown Diamonds at Brilliance.com

Brilliance.com is, it turns out, very honest about the benefits of lab diamonds without trying to hide them. In fact, they’re very open about the many reasons lab-created diamonds are better than mined diamonds, which we like.

Since our last review of Brilliance.com, we’ve noticed a positive shift in how prominently lab-grown diamond jewelry is featured. Previously, several jewelry categories featured only mined diamonds, and lab diamonds were a little hidden on the site. However, this is not uncommon in the industry since margins on mined diamonds tend to be higher (and so do prices). Now, they’re much easier to find and are alongside mined diamond options in several sections, including engagement rings and fine jewelry. This improvement makes the browsing experience smoother for shoppers specifically seeking lab-grown diamonds.

Next, in our Brilliance.com review, we’ll assess the lab-grown diamond inventory

Diamond Selection and Quality

In our review of Brilliance.com, we will evaluate the inventory of lab-grown diamonds by examining both their selection of loose lab diamonds and the pre-set jewelry featuring lab-created diamonds.

See also our lab-grown diamond buying guide if you need help finding the perfect lab-created diamond.

Loose Diamond Inventory

As of the time of our review, Brilliance.com offers an impressive selection of 615,951 lab-grown diamonds, which is more than four times the number of loose diamonds available during our last review. This makes Brilliance.com’s loose diamond inventory the largest of any online diamond jeweler, even surpassing Ritani’s extensive selection. But there’s a catch.

As we’ll come back to later, Brilliance.com does not, in fact, have all these diamonds in stock. Instead, they list diamonds available based on diamond inventory feeds from wholesalers. That means that when you pick a specific diamond, Brilliance.com first has to confirm that the diamond in question is still available, and they’ll then place an order for it.

The problem is that you’re not guaranteed to get the exact stone you’ve been looking at. This is a huge drawback and hindrance to the diamond purchase due diligence process.

It’s not uncommon in the industry. However, Brilliance.com seems more prone to using these lists and their drawbacks. In addition to the risk of not getting the diamond you wanted, it delays the order process- at a potentially time-critical moment.

How We Compared the Diamond Inventory

Ignoring the use of wholesale diamond lists, we’ll continue our Brilliance review by further assessing their “inventory”. When we evaluate diamond inventory in our lab-grown diamond reviews, we also use a reference diamond, a lab diamond suitable for many purposes, and a popular weight.

Our reference diamond is a round brilliant-cut stone, weighing 0.90-1.10 carat* The clarity is VS1-2 with an I or J color grade (some will prefer a higher color grade). The diamond cut, of course, is always the highest possible. With lab-grown diamonds, most often certified by IGI, that is ideal. The lab diamonds at Brilliance.com are certified mainly by IGI, so that’s the grade we’ll use.

*You can often find an excellent deal by going under and over the popular 1-carat.

Narrowing our search to these criteria, we found 53 “available” diamonds, which is fewer than in our previous review (178 diamonds in 2024). On the plus side, Brilliance.com has significantly improved the presentation of its diamonds. Every listing now includes actual photos of the individual diamond and a 360° viewing video, which allows shoppers to examine brilliance, symmetry, and inclusions directly. The video quality is decent, and while the lighting and background vary slightly, it’s a major step forward compared to the missing images we saw two years ago.

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 with pre-selected diamonds. However, we don’t generally recommend that you do that since many jewelers use sub-par diamonds for pre-set jewelry and because you’ll get a better deal and diamond by choosing it yourself.

The main issue is diamond cut, which they often do not list. This is absurd since the diamond cut is the most critical aspect of any diamond. A notable exception is Ritani, who uses ideal-cut diamonds.

It turns out that another notable exception to that rule is Brilliance.com. Or so it seems. The good part first. Unlike at many other places where you must first ask, you can see the diamond cut grade of all pre-set jewelry.

Diamond Quality

For the most part, the cut grade listed is ideal, which is the best grade that IGI employs, while GIA uses excellent as the best cut grade. And that’s when we got a little confused. When we look at mined pre-set jewelry, they have listed the cut grade as ideal. So either they don’t use GIA-graded diamonds (the best diamond lab for mined diamonds). Or they grade the diamonds themselves, just like Vrai does.

Now, for smaller diamonds, typically access stones or when they are too small to grade (such as a tennis diamond bracelet with 50+ diamonds totaling 1 carat). In that case, the grading may be carried out in-house or by the vendor. And you’ll have to trust the quality or ensure you can return the product.

However, an independent diamond laboratory should grade diamonds of a specific size. Unfortunately, as Brilliance.com’s customer support confirmed, that’s not the case at Brilliance.com.

All the diamonds in the non custom jewlery are certified and graded in house by our master gemologist

Brilliance.com

So, while it’s fantastic that Brilliance.com uses ideal cut diamonds, they are, in fact, graded by themselves.

However, at Brilliance.com, they can customize any jewelry and use any diamond you find in the mined or lab-grown inventory. And that’s precisely what we recommend that you do.

That leads us to the second part: unlike in previous years, Brilliance.com now offers a much broader selection of lab diamond jewelry in its inventory. While their early focus was almost entirely on mined diamonds, their 2026 collection includes lab-created options across many popular categories, such as engagement rings, necklaces, bracelets, and earrings.

That said, the ability to customize any jewelry with the diamond of choice is a huge benefit, which we’ll get back to later in the Brilliance.com review.

Diamond Certification at Brilliance.com

As we have already touched on, diamonds in pre-set jewelry are all graded in-house, which, at best, is a helpful guide. So, instead, you should choose your own diamonds from their diamond inventory. All lab-grown diamonds that Brilliance.com lists are certified by IGI, the leading lab-grown diamond grading institute.

So, if you pick a diamond from their loose diamond inventory, you can trust that you are buying a legitimate diamond and that the grade is trustworthy. As we’ll see in the following section of the Brilliance.com review, you get access to all grading reports by contacting customer service.

Buying Diamonds on Brilliance.com

The next part of our Brilliance.com review is an evaluation of the buying experience on their website.

Like many other online diamond retailers, purchasing is straightforward and user-friendly. Either choose a piece of jewelry already set with a diamond or begin by finding a loose diamond you want to use (we recommend the latter).

Customizing Diamond Jewelry

While you can only customize diamond rings online, contact the Brilliance.com support team, who can help you customize any jewelry. That’s really great, though we would have preferred the option to do it online as well. It’s not as smooth a process going through support, but it’s doable, and something Ritani also does for some jewelry types.

Finding a diamond is easy and almost identical to most other online jewelers. You enter your search criteria, and the website returns diamonds that fit those criteria. Many results are returned, but these are based on wholesale diamond feeds. So you may want to find a backup stone in case the first one is unavailable.

If you need help deciding what to look for, follow the steps in our lab-grown diamond buying guide.

Buying Support and Guidance

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

Brilliance.com also offers this service. You can either call, chat, or set up a virtual appointment. Again, it’s straightforward, and their customer service team is very responsive (even on the weekend, they’ll respond in less than a minute). We once reached out to them at 10 p.m. and got a reply right away. That’s pretty impressive.

You can’t schedule virtual appointments online. Instead, you have to fill out a request form. Other jewelers, such as James Allen, Ritani, Grown Brilliance, and Brilliant Earth, allow you to schedule appointments online, which is much more convenient.

My Personal Experience with Brilliance.com’s Customer Service

Requesting a Diamond Certificate

As mentioned, diamond certificates are not available online Brilliance.com. Instead, you have to contact their customer support. They will gladly send it to you, but it really impacts your ability to compare and assess the diamonds you are considering.

I was a bit annoyed that I had to request the diamond certificate manually while browsing. I first reached out via chat, where someone named Chase responded almost immediately and asked for the diamond’s stock number. I sent him the link right away, but it took a little while before he got back to me. Of course, before helping, he wanted my name, email, and phone number “in case we got disconnected.” Pretty annoying, that’s a lot of personal information to hand over when you’re just browsing. But then again, most diamond retailers require this when you contact them.

Chat Response Time and Process

That said, the process was fairly quick. Less than 10 minutes passed from the time I first reached out to when I received the IGI certificate. Not bad at all, though I’d still prefer if the certificate were simply available on the product page, like competitors Ritani and James Allen offer.

Customer Support Experience

At times, it felt a bit like chatting with Amazon support — moments of silence where the agent seemed to disappear for a bit. I asked if he could recommend another lab diamond and he came up with a pretty decent option. But when I asked if there were any other diamonds he could recommend, but he simply replied that the one he’d chosen was the best. It would have been nice to get a few options. On the other hand, if you do your own research, you probably won’t need much help choosing. When I said I needed time to think, he quickly added, “Currently we have the best Black Friday offer, and it can end anytime.”

To be honest, I’m not sure how knowledgeable the agent was. He was friendly and fairly quick to respond, but would I trust his advice if I were spending $3,000 on a huge diamond? Probably not.

Final Impression

I really dislike pushy sales tactics, which is one of the many reasons I prefer buying online. The good thing is, you can just close the chat and keep shopping in peace.

All in all, customer service is friendly and helpful, though they are a little pushy and sometimes seem more focused on getting you closer to a sale than answering your questions.

Inspecting Diamonds on Brilliance.com

In this section of our Brilliance.com review, we’ll assess the diamond inspection features on their site. This is a crucial part of the buying process and probably one of the most complicated. Therefore, you must have access to the right features and information.

Once you find a suitable diamond shortlist, you inspect it. Then, you compare the diamonds by clicking from the results page to the individual diamond page.

How to Inspect Diamonds on Brilliance.com

At Brilliance.com, this is similar to how it works at other online jewelers. You’ll land on a page with many additional details about the particular diamond, images, and 360-degree video.

The image presented is decent quality and easy to zoom in, though the quality could have been a little better (a higher resolution would have been nice). The 360-degree video images are also a must-have feature, but again, the resolution is a little low. In this case, we find it to be too low.

The video feature is precious, allowing you to loop the video by looking at specific aspects of the diamond (looking for inclusions or blemishes). It’s just a shame the quality is almost too low for it to be helpful.

You can also access the diamond measurements, which you can compare against the ideal type (learn more about lab diamond shapes).

Lastly, and very importantly, you won’t get direct access to the diamond certificate, which details the diamond grades and any inclusions or blemishes that could impact the diamond’s clarity.

In the past, Brillance.com gave shoppers direct access to the certificate. But as we’ve covered, now you have to reach out to customer service.

In summary, the diamond inspection features are good, but we really dislike that you don’t get direct access to diamond certificates. Also, the image, particularly the 360-degree video, is of too low quality for you to perform the proper due diligence.

Brilliance.com Diamond Prices

When evaluating prices in our review of Brilliance.com, we start by looking at the cost of loose diamonds. These are much easier to compare, even though diamonds are unique and inherently impossible to compare precisely. So, instead, we compare the overall price ranges for high-quality diamonds.

On average, the prices at Brilliance.com are very competitive and close to the price leaders Brilliant Earth, Grown Brilliance, and Ritani. As a result, you’ll often find lab-grown diamond sales at Brilliance.com and be able to make a good deal.

We recommend signing up for our newsletter to be alerted of sales and see any ongoing sales like Black Friday or holiday sales.

Diamond Price Comparison

Using our reference diamond as a yardstick, the prices at Brilliance.com range from $675 to a staggering $5899. Based on our appraisal, the widespread price variation seems to be due to Brilliance.com sourcing its inventory from various places rather than differences in quality alone.

That also explains how Brilliance.com sometimes matches the prices of price leaders such as Ritani and sometimes is closer to those of Vrai or Best Brilliance. Overall, Brilliance.com does offer competitive prices. So, if you don’t mind the potentially longer wait and uncertainty of the diamond’s availability, you might be able to get a great deal.

Jewelry Price Comparison

Ready-to-Ship 0.50 tcw Lab-Grown Diamond Stud Earrings (2026)

See how Brilliance.com stacks up against Ritani, Grown Brilliance, Brilliant Earth, and James Allen.

Jeweler	Price (USD)	Cut & Certification	Return Policy	Notes
James Allen	$340	F–G color · VS2–SI1 clarity · Cut: n/a	30 days	Preset earrings without a specified cut grade
Brilliant Earth	$375	F–G color · VS clarity · Cut: n/a	30 days	Preset earrings without a specified cut grade
Grown Brilliance	$395	F color · VS2 clarity · Excellent (IGI)	30 days	Good value and reliable craftsmanship
Ritani	$419	G–H color · VS clarity · Ideal (IGI certified)	30 days	Transparent IGI certification and quality diamonds
Brilliance.com	$575	G color · VS2 clarity · Ideal (in-house graded)	30 days (from shipping)	Slightly pricier and in-house graded

Their lab-grown diamond stud earrings run from $415 for 0.25 carat total weight (that is 0.125 carats each) to $5315 for 4 total carats. A 1 total carat set of lab-diamond stud earrings costs $1,155, which puts Brilliance.com well above $589,99 at Ritani (and often you’ll even find a Ritani diamond sale).

It’s critical to note that the diamond cut quality at Ritani is ideal, the best. At the same time, it’s lower at Clean Origin, and we recommend the perfect pair at Ritani over Clean Origin.

Brilliance.com lists the cut grade as ‘ideal’, but as we confirmed through customer support, these diamonds have been graded by themselves, just like Vrai does. While they assured us that a professional gemologist reviews each diamond and even includes an “appraisal letter,” this document holds little real value. It may sound official, but it’s essentially an internal estimate and it’s not a substitute for an independent lab certification like IGI or GIA.

Pro Tip:
Create your own diamond studs and handpick the stones. You’ll get much better sparkle and higher quality for your budget than with most preset options. Additionally, you’ll receive an official certificate.

See our comparison of all lab-grown diamond earring prices.

Brilliance.com Shipping and Returns

The last part of our Brilliance.com review considers their shipping and return policies.

The shipping costs at Brilliance.com are a little complicated, so they have a table. It’s even a little contradictory. Brilliance.com states shipping is free, but orders over $2,000 cost $35 to ship. That’s not exactly free, even if it is the nicer overnight delivery option. We think they should just offer free expedited shipping on all orders like James Allen and others do. But at least you don’t have to pay for all shipping like with Zales.

Brilliance.com offers 30-day free returns, which is pretty standard. However, note that the period starts at the time of shipping, not when you receive it.

Also, note that an order can’t be canceled once it begins processing. That’s odd, considering Brilliance.com’s processing is relatively slow. However, again, it’s likely due to Brilliance.com relying on wholesale diamond lists and buying the diamond from the wholesaler.

They also state that custom items can’t be returned or canceled. It makes sense that engraved items or something very custom and unsellable to someone else has limited returns. However, custom items can still be resold, and other diamond jewelers offer much more lenient terms for custom items.

Brilliance.com Customer Reviews

When evaluating Brilliance.com’s reputation online, we considered a combination of third-party customer feedback from Trustpilot, Reddit, and review sites to gain a balanced view of real customer experiences.

Trustpilot

Brilliance.com has 4.9 stars on Trustpilot, with many customers praising its attentive customer service, quick responses, and a smooth buying experience. However, if you dig a bit deeper, their negative reviews seem somewhat alarming. For example, several negative reviews report long wait times, lack of, or, in some cases, even unpleasant communication, and problems getting a refund.

Reddit

There aren’t many discussions about Brilliance.com on Reddit, especially compared to the overwhelmingly positive reviews we found on Trustpilot. While some Reddit users share great experiences and satisfaction with their purchases, others report long wait times with orders stuck in the “polishing and setting” stage for weeks, as well as frustrating communication with customer service.

A few also mention the company’s D rating on the Better Business Bureau (BBB). While the number of complaints isn’t unusually high for a large online retailer, the low rating does raise some concerns about how effectively Brilliance.com handles customer issues.

Pros and Cons of Brilliance.com

Before we reach our final verdict on Brilliance.com, we list the pros and cons we have encountered throughout our review.

Pros

• Low prices (loose diamonds)
• Extensive inventory (even though not own stock)
• Satisfactory customer service
• Vast customization options

Cons

• Not their own inventory but wholesale lists
• Subjective grading of pre-set diamond jewelry
• Often low-quality 360-degree videos
• Confusing and sub-par shipping and terms
• Customer feedback is mixed; positive Trustpilot reviews contrast with slower response times and complaints on Reddit and the BBB.

Our Brilliance.com Review Verdict

In our updated 2026 Brilliance.com review, we have found both positives and negatives.

Positives include competitive prices, good and responsive support, and the option to schedule virtual appointments, even if they are a little cumbersome.

We also appreciate their vast inventory of lab-grown diamonds, though it’s not really their own inventory but rather wholesale lists. Nevertheless, it does give the buyer a wide range of options.

The diamond inspection process is adequate, but it could be improved.

Lastly, we appreciate that they clearly list the many benefits of lab-grown diamonds and do not try to hide them to not speak poorly about mined diamonds.

On the negative side, we were disappointed in the lack of independent grading of the diamonds they use for pre-set jewelry.

While the diamond inspection is generally adequate, we think the resolution of the images, particularly the 360-degree video images, should be improved. We also did not like that diamond certificates were not readily available as they used to be.

Another issue is the potential uncertainty of getting the actual diamond you have looked at due to the use of wholesale diamond lists. We recommend that you find at least one alternative option. In addition, it could delay the order process, which may be problematic if you’re running short on time. So make sure you’re buying well in advance of your need.

Lastly, we didn’t like their return policies and confusing shipping options. If you are choosing your own diamond and thus “customizing,” we recommend getting written assurance that you can return the product for a full refund.

3 Diamond Jewelers We Like Better Than Brilliance.com

Best quality diamond inventory, lowest prices

Sustainably graded lab diamonds, low prices

Best service, guidance, diamond prices & quality

Our Final Brilliance.com Review Score

All things considered, Brilliance.com is not a bad place to buy diamonds. But it’s also not the best. Brilliance.com falls behind the best places to purchase lab-grown diamonds. But they are also far from the poor experiences of Helzberg, Lightbox Jewelry, and Zales. We landed a review score of 3.9 out of 5.

Who is Brilliance.com Good For?

If you find the perfect diamond at the right price at Brilliance.com, and you don’t mind the potential extra wait or choosing another diamond, and if you are assured you can return your jewelry for a full refund, then we won’t hesitate to recommend that you buy it from them.

Who is Brilliance.com Not Good For?

However, in case you want to avoid all those “ifs, ” we recommend you compare with our highest-rated lab-grown diamond sellers, such as James Allen, Grown Brilliance, Brilliant Earth, and Ritani, for their low prices, extensive inventories, and superior service and support. You can read more about them and other sellers in our lab-grown diamond seller reviews section.
