Bottom-line verdict of our Brilliance.com review
Brilliance.com offers a huge choice of lab-grown diamonds, useful search tools, and helpful support. We rate it 3.9 out of 5. It is worth checking, especially if you enjoy comparing stones, but it is not our first choice.
The strongest reason to shop here is selection. In our August 2026 check, Brilliance.com listed more than 535,000 lab-grown diamonds and hundreds of settings for the stone we selected. The ring builder worked well, and support found both IGI grading reports we asked for.
Price and returns are the main drawbacks. Ritani was about half the price for the closest two stones in our latest comparison. Brilliance.com's 30-day return offer also has more conditions than the headline suggests. Before buying, compare the full price at Ritani, Brilliant Earth, and Grown Brilliance, then confirm the grading report, delivery estimate, and return terms for your exact order.
Who is Brilliance.com, and is it legit?
Yes. Brilliance.com is a legitimate online jeweler run by Brilliance, L.L.C., an active company in the Florida corporate registry. The retailer also lists phone numbers and a Boynton Beach mailing address on its contact page.
Our bottom-line view is that Brilliance.com is a real and established jeweler with a very large diamond selection. We still recommend comparing prices and reading the return terms before ordering.
Brilliance.com is not Grown Brilliance or Best Brilliance Diamonds. They are separate retailers despite the similar names. This review is only about Brilliance.com.
Brilliance.com sells both mined and lab-grown diamonds
Brilliance.com sells loose natural and lab-grown diamonds, engagement-ring settings, and finished jewelry. This review focuses on its lab-grown range.
What changed since our earlier reviews
Brilliance.com's presentation of lab-grown diamonds has improved since our original review. The category used to be less prominent in parts of the site. It is now much easier to find lab-grown choices alongside mined-diamond engagement rings and jewelry.
Do not rely on the word “certified” alone. Ask for the grading report and check that its number, measurements, and grades match the exact diamond you are buying. The report should also tell you how the diamond was grown. If treatment matters to you, ask about that too.
Diamond selection and quality
Selection is Brilliance.com's clearest strength. On August 30, 2026, the site displayed 535,499 lab-grown results. Its filters covered shape, origin, carat, price, images, quick shipping, color, clarity, and more. After we selected a 2.02-carat emerald-cut diamond, the ring builder offered 338 compatible settings.
The total is a website result count, so it may include stones held by suppliers and does not guarantee that every diamond is still available. Even so, Brilliance.com consistently gives buyers a very large pool to search.
Loose diamond inventory
Our November 2025 update recorded 615,951 lab-grown results. The number changes as stones enter and leave supplier inventories, but the overall pattern is clear: Brilliance.com carries one of the largest searchable ranges we have reviewed.
Save the stock number and ask Brilliance.com to confirm availability before planning around one diamond. This is especially important if you have a fixed proposal date. Support told us it would contact the buyer before substituting another stone if the original became unavailable or was damaged during inspection.
How we compared the diamond inventory
In earlier updates, we used the same “reference diamond” filters to make the inventory checks more useful. In November 2025, the search found 53 round lab-grown diamonds with images between 0.90 and 1.10 carats, I–J color, VS1–VS2 clarity, and a top cut grade. The same search had found 178 in 2024. This shows how quickly a huge headline number can shrink once you add practical filters.
For our 2026 check, we selected a larger round and emerald-cut diamond. Support supplied the matching IGI reports:
| Sample | Displayed specification and price | Report supplied by support | What the report confirmed |
|---|---|---|---|
| Round, stock LG44155673 | 2.07 ct, E, VVS2, IGI, merchant “Super Ideal,” $1,321 | IGI LG813672683 | 2.07 ct, E, VVS2, Ideal round, CVD, Type IIa |
| Emerald, stock LG42085519 | 2.02 ct, E, VVS2, IGI, merchant “Super Ideal,” $1,204 | IGI LG810648743 | 2.02 ct, E, VVS2 emerald, CVD, Type IIa |
The stock numbers, carat weights, color, clarity, shape, and lab details matched. Both reports identified CVD-grown, Type IIa diamonds. The support expert said the reports did not show post-growth treatment, although neither report gave a direct treatment conclusion.
Brilliance.com called both stones “Super Ideal,” but that is its own label. The IGI report for the emerald we checked did not include an overall cut grade. IGI does grade fancy shapes when that service is requested, so inspect the report, video, measurements, and light return rather than assuming Brilliance.com's label came from the lab.
Pre-set diamond inventory
Preset jewelry is quick and convenient, though it gives you less control over the individual diamonds. In November 2025, a preset stud listing used an “Ideal” cut description. Support told us that diamonds in non-custom jewelry were checked in-house rather than graded one by one by an outside laboratory.
Our August 2026 sample was a pair of four-petal earrings with eight marquise lab-grown diamonds totaling 2.00 carats. The listing gave E–F color and VS1 clarity ranges. It did not name a grading lab or show a report number, growth method, or treatment details.
That is normal for small melee diamonds, where a separate laboratory report for every tiny stone would add cost without helping much. A good in-house quality check can be enough. Larger center stones are different. For a meaningful center diamond, we want an independent IGI or GIA report. A store appraisal is useful for insurance, but it is not the same as independent grading.
For build-your-own diamond studs, handpick both loose stones when possible. You can compare their measurements, cut, videos, and reports, then choose a well-matched pair instead of accepting a broad preset grade range.
Inspecting diamonds on Brilliance.com
Once you have a shortlist, inspect each diamond instead of choosing from grades alone. A stone-specific image or video can reveal inclusions, a strong bow tie, windowing, or a shape you simply do not like. The grading report lets you verify the measurements and grades.
Brilliance.com's inspection tools have changed over time. In 2022, product pages included still images, a 360-degree viewer, measurements, and report controls. We found some of the video too low-resolution for a close inspection. The two diamonds we checked in 2026 had a still image and a 360 control.
The two current product pages did not show the grading-report number or growth method where we could see them. The certificate button also did not open the report during our check. Support solved this by sending the exact IGI reports for both stones.
We would prefer to see the report and report number directly on every loose-diamond page. Until then, use Brilliance.com's FAQ process for requesting a missing image or report. Match the report number, measurements, shape, carat, color, and clarity to the listing before checkout.
Brilliance.com diamond prices
Diamond prices vary from stone to stone. To make the comparison useful, we looked for the closest available matches by shape, carat, color, clarity, grading lab, measurements, and proportions.
Diamond price comparison
Our August 2026 price check put Brilliance.com in the middle. It was far more expensive than Ritani for the closest matches, but much cheaper than Brilliant Earth and the Grown Brilliance round we found.
| Seller | Matched round | Difference from Brilliance | Matched emerald | Difference from Brilliance |
|---|---|---|---|---|
| Brilliance.com | $924.70 with LAB30 ($1,321 displayed) | Baseline | $1,204 | Baseline |
| Ritani | $463 | 49.9% lower | $472 | 60.8% lower |
| Brilliant Earth | $2,100 | 127.1% higher | $2,590 | 115.1% higher |
| Grown Brilliance | $1,615 | 74.7% higher | Not captured | — |
The round diamonds were 2.00–2.07 carats, E color, VVS2 clarity, and IGI graded. Brilliance.com's LAB30 code reduced its round from $1,321 to $924.70 in our cart. The code was not shown for the emerald. The two emeralds were both 2.02 carats, E color, VVS2 clarity, and IGI graded, although the Brilliant Earth stone had different proportions.
The exact stock numbers were Brilliance.com LG44155673, Ritani D-TSZJP7S21Z, Brilliant Earth 83857172, and Grown Brilliance MA-263188-013 for the round diamonds. The emeralds were Brilliance.com LG42085519, Ritani D-8JBYFCPXFZ, and Brilliant Earth 85892607.
Ritani showed report details and verification links on the product pages we checked. Brilliance.com sent its report details after we contacted support. Prices and inventory change every day, so run the same comparison when you are ready to buy.
Our 2026 ring basket
On August 30, 2026, our test basket combined the $1,204 emerald with a $650 classic solitaire setting. The LABORDAY code took $162.50, or 25%, off the setting. It did not discount the loose diamond. The pre-tax total was $1,691.50 with free shipping shown.
The code had to be entered manually, and the cart accepted one code at a time. We stopped before entering a shipping address, so tax was not included. Check the current sale terms before ordering.
Buying diamonds on Brilliance.com
You can buy finished jewelry or choose a loose diamond and pair it with a setting. We usually prefer the second route because it gives you more control over the diamond, grading report, proportions, and total price.
Customizing diamond jewelry
The ring builder was easy to use in our latest check. After we selected the emerald, it showed compatible settings and carried the correct diamond into a 14K yellow-gold solitaire in size 7. The cart kept both product numbers, metal, size, discount, total, and free shipping.
In earlier reviews, support could also help with jewelry changes beyond the options shown online. If you request a change, ask whether the final piece will be classed as custom or special order. That can affect whether it can be returned.
There were also friction points:
- A “Quick Shipping” badge on the emerald did not show an earlier ship date than the ordinary round sample. Support later estimated about four weeks for that emerald in the 14K yellow-gold Classic Solitaire, size 7, without engraving.
- The public promotion had to be entered manually.
- A $30 engraving option allowed up to 30 characters and several fonts, but it did not warn that engraving may affect return eligibility.
- Checkout asked for email, phone, name, and address before the payment and final review steps.
Save a copy of your exact ring setup and ask for a written delivery estimate if the date matters.
Production, shipping, and returns
Brilliance.com's shipping policy says US shipping is free and insured. Orders below $250 use ground service, orders from $250 to under $2,000 use two-day service, and orders of $2,000 or more use overnight service. An adult signature is required. For apartment buildings, the policy says insurance ends when the package is delivered to the building.
On August 30, both loose diamonds showed an estimated September 9 ship date, while the preset earrings showed September 4. The finished ring took longer. Support estimated about four weeks for our emerald-cut diamond in the 14K yellow-gold solitaire, size 7, without engraving.
Brilliance.com advertises 30-day returns, but the details are important:
- You must call for a return code.
- A US return must arrive at Brilliance within 30 days of the original shipment date.
- You arrange and insure the return shipment.
- Custom, special-order, setting-only, melee, resized, and some collection items may be excluded.
- The engraving fee is non-refundable. Support also said a ring becomes non-returnable after resizing.
- The merchant says accepted refunds, exchanges, or credits are issued within 15–25 business days.
- An order cannot be canceled once processing begins. An eligible item may still be returned.
Support said our standard, unengraved test ring could be returned or exchanged within 30 days of shipment. We also found a disagreement between the public pages. The returns page says a missing original certificate voids the return, while the terms list a $250 replacement fee. Support told us the return would still be accepted with the fee.
The terms also say some loose diamonds may be final sale and a rush return may have a 10% restocking fee. Ask Brilliance.com to confirm your exact item's return status in writing before paying, especially for engraving, resizing, rush service, or custom work.
Warranty, resizing, and upgrades
The warranty and upgrade page includes manufacturing-defect coverage, two professional cleanings per year, and one resize within 90 days. Support described the resize itself as free. The customer still pays shipping, and the ring becomes non-returnable after it is resized.
Work by another jeweler can void the warranty. The services are limited to US customers, are not transferable, and Brilliance decides whether damage is a manufacturing defect.
The published diamond upgrade program is for qualifying certified natural diamonds. It does not promise a lifetime trade-in for a lab-grown diamond.
Customer service: our 2025 and 2026 tests
Brilliance.com's contact page advertises expert help 24/7. In our 2025 and 2026 checks, support helped us obtain grading reports and answered several order questions. The quality of the advice varied, but both conversations were useful.
Buying support and guidance
Brilliance.com offers phone, chat, and virtual appointments. Support is most useful when you already have a shortlist and need a grading report, availability check, alternative stone, or answer about a custom design. We would still compare the options ourselves before accepting a recommendation.
Our November 2025 support test
In November 2025, the first reply came almost immediately and the requested IGI report arrived in under ten minutes. We liked how quickly the report arrived, but we did not like being asked for a name, email address, and phone number just to see it.
The agent suggested a reasonable alternative diamond when asked, though we received only one option. When we said we needed time to think, the chat moved to a Black Friday offer that could end at any time. A separate reply gave a normal completion and delivery estimate of 15–20 business days and said the company would try to meet a specific date.
Our impression was mostly positive. The service was friendly, quick, and able to find the report. The Black Friday urgency was a negative. One reason we shop online is to compare diamonds without sales pressure.
What current support has confirmed
In August 2026, support supplied both reports we requested. Round stock LG44155673 matched IGI LG813672683. Emerald stock LG42085519 matched IGI LG810648743. The expert said the reports did not show post-growth treatment, although the documents did not give a direct treatment conclusion.
Support also answered our order questions:
- The emerald-cut ring we built had an estimated lead time of about four weeks with standard free delivery.
- The standard, unengraved ring could be returned or exchanged within 30 days of shipment.
- If the diamond became unavailable or was damaged during inspection, Brilliance.com would contact the buyer before choosing another stone.
- A missing grading report would lead to the replacement fee in the terms instead of voiding the return.
- The expert said the engraving fee is non-refundable and that a ring becomes non-returnable after resizing. The expert described one resize within 90 days as free, although the published policy still says shipping charges apply.
The expert was responsive, found both reports, checked the exact ring, and answered the key questions in writing. It took a few follow-ups to get all the details. We did not place an order, so this does not tell us how support handles a difficult delivery, resize, or return.
Customer reviews and complaints
Brilliance.com's public reviews were mostly positive when we checked on August 30, 2026. Complaints often focused on delivery, communication, returns, and repairs, so post-order service is still worth watching.
Trustpilot
Trustpilot displayed 4.9 out of 5 from 4,751 reviews, including 735 from the previous 12 months. We also read the 20 reviews on the current “Most recent” page. Fifteen were five-star, one was four-star, two were three-star, and two were one-star.
Positive reviewers often praised the finished jewelry, communication, and timing. Lower ratings more often mentioned communication, guidance, or a difference between the item and its online presentation. The 20 recent reviews were marked “Unprompted” rather than purchase-verified, so we use them to spot themes instead of treating them as a customer-satisfaction survey.
BBB reviews and complaints
The BBB profile showed an A business rating and no accreditation. The customer-review page showed 4.4 out of 5 from 20 reviews. The complaint page listed 35 complaints over three years, with 24 closed in the previous 12 months.
Recent complaints included issues with diamond or report identification, delivery, return approval, cancellation, promotions, repairs, and resizing. BBB complaint totals do not show how many orders Brilliance.com handled, but the stories are a useful reminder to save the listing, grading report, delivery promise, and written return answers.
Earlier versions of this review also checked Reddit. We found fewer useful discussions there. Some shoppers described good purchases, while others reported long waits or poor communication. We did not repeat a full Reddit review in August 2026.
Overall, Brilliance.com's public reputation is positive. The complaints make its delivery and return details worth checking before a high-value order.
Frequently asked questions
Is Brilliance.com legit?
Yes. Brilliance.com is a legitimate online jeweler run by a registered Florida business. It publishes its contact details and has thousands of customer reviews. Our verdict is that it is worth considering for its large selection, though we found lower prices at Ritani and clearer return terms elsewhere.
Why can Brilliance.com prices look low?
Its large supplier inventory and regular promotions can produce some low prices. In our August 30 check, Brilliance.com cost more than Ritani for the closest matches and less than Brilliant Earth and Grown Brilliance. Compare the exact diamond and full ring price because the result changes with inventory and sale codes.
Are Brilliance.com lab-grown diamonds certified?
The two loose diamonds we checked had IGI reports, and Brilliance.com says its lab-grown diamonds come with an IGI or GIA report. Preset jewelry may use diamonds checked in-house instead. Ask for the report before buying a meaningful center stone, and match it to the exact stock number. Small melee diamonds in a finished piece often will not have separate reports.
Does Brilliance.com have free 30-day returns?
Brilliance.com advertises 30-day returns, but return shipping is not free. The published policy says a US return must arrive within 30 days of the original shipment. Custom work, some special orders, resized rings, and other listed items may not qualify. Ask for written confirmation before ordering engraving, rush service, resizing, or a custom design.
Does Brilliance.com have a showroom?
No. Brilliance.com presents itself as an online jeweler and does not advertise a customer showroom. Its Boynton Beach address is a mailing address.
Is Brilliance.com the same as Grown Brilliance?
No. Brilliance.com, Grown Brilliance, and Best Brilliance Diamonds are separate retailers. Similar names should not be used interchangeably in reviews, links, or recommendations.
How we have reviewed Brilliance.com
We first published this Brilliance.com review in October 2022 and have updated it every year since. LabGrownCarats has reviewed diamond sellers since 2020. This page combines the useful findings from the original review with later checks as the store, prices, and policies have changed.
For the August 2026 update, we searched the US store in USD, inspected round and emerald-cut loose diamonds, built an emerald-cut ring, tested the cart and sale codes, reviewed preset earrings, and went through checkout until the site requested personal details. We read the shipping, return, warranty, resizing, FAQ, contact, and terms pages. We also contacted support for the grading reports and written answers about delivery, returns, missing certificates, resizing, and replacement stones.
We did not place an order in the latest test. That means we did not test delivery, the finished jewelry, resizing, a return, or a refund. Older screenshots in this review show what Brilliance.com looked like on the date named in each caption, so current prices and layouts may differ.
We do not have an affiliate partnership with Brilliance.com. Some links to alternative jewelers are affiliate links, which means we may earn a commission if you buy through them. This does not change the price you pay or how we rate Brilliance.com.
