Lightbox Alternatives
De Beers closed its lab-grown brand. If you arrived from a Lightbox link, this is what happened and where the alternatives are.
Lightbox has closed. De Beers announced its intention to shut the brand on 8 May 2025, citing a roughly 90% fall in wholesale lab-grown prices, and lightboxjewelry.com served a store-unavailable page when we checked on 19 August 2026. Here is where displaced Lightbox buyers can go.

What Lightbox Was, And What Replaces It
| Brand | Status | Grading | What it was good at | Where you can see it |
|---|---|---|---|---|
| Lightbox (for reference) | Closed — announced 8 May 2025, store offline | None at launch; later GIA batch verification | Flat per-carat pricing and the lowest entry price in the category | Was stocked by US jewelers |
| Beyond Carat | Trading | IGI on every stone, report in the box | A fixed D–F, VVS–VS, Excellent-cut band, made to order | Online only, video or phone consultation |
| Rare Carat | Trading | GIA, IGI or GCAL — filterable | Scale and the lowest available prices | Online, US and Canada only |
| Brilliant Earth | Trading | Predominantly IGI, some GIA, GCAL and HRD | Trying rings on, and a natural option | US showrooms |
| MiaDonna | Trading | Certificate supplied; laboratory not named | A 60-day free return window and B Corp certification | One flagship, Portland OR |
Lightbox facts are cited to De Beers, JCK, National Jeweler and Rapaport, with the storefront status confirmed by direct request on 19 August 2026. The historic Lightbox prices further down are published as an exception to our usual rule against printing competitor prices — the business no longer trades, so they cannot drift, and the comparison is dishonest without them.

Where Lightbox Won, Where We Win
Where Lightbox won
- Price. Complete engagement rings started at $500 in the 2023 range, well below our $1,049 entry, and the standard stone tier was $800 per carat
- Flat, linear pricing regardless of colour and clarity — genuinely clearer than any 4Cs-based model, ours included
- The De Beers name and balance sheet behind it, which is exactly the reassurance a first-time buyer looks for
- Retail distribution through physical jewelers, so you could see a stone in person before buying
Where Beyond Carat wins
- A per-stone IGI grading report in the box, rather than a batch-level verification
- A published floor of D, E or F colour, VVS or VS clarity and Excellent cut on everything we sell
- Rings made to order rather than picked from a fixed, mass-produced range
- A lifetime manufacturing warranty from a business that is still trading and answering the phone
One caveat we owe you: at the Lightbox Finest grade — VVS clarity in D, E or F colour, the same band we sell — the stone alone was $1,500 per carat in 2023, so on like-for-like grade our entry came in lower. On headline price Lightbox won. Both statements are true, and a page that printed only one of them would be selling you something.
The Closure, With Dates
Lightbox launched in 2018 as De Beers’ lab-grown jewelry brand, built on flat per-carat pricing, and from late 2020 its stones came out of a purpose-built $94 million facility in Gresham, Oregon. On 8 May 2025 De Beers announced its intention to close the business, stating that lab-grown diamond prices in the jewellery sector had fallen 90% at wholesale and were tracking closer to a cost-plus model. Consumer operations were to stop by that summer and factory operations by the end of 2025, with the Gresham plant moving to industrial diamond production under Element Six.
The financial picture behind the decision was published at the same time: Lightbox lost $101.3 million in 2023, against a $22.3 million loss in 2022. De Beers also said it was discussing the sale of certain assets, including inventory, with potential buyers. No completed sale and no relaunch under new ownership has been found, so we are not telling you the brand is coming back.
Our own check on 19 August 2026 found lightboxjewelry.com returning the Shopify platform message “This store is unavailable”. Archived captures show the storefront still responding normally in mid-June 2025 and redirecting from late July 2025 onward, which matches the announced timetable. Primary sources: the De Beers announcement, JCK and National Jeweler.
What The Closure Says About Lab-Grown Prices
Read it straight, not as a win for anybody
It would be easy for a lab-grown seller to present this as De Beers retreating. That reading does not survive contact with the announcement. De Beers left the category because the price of lab-grown rough collapsed — its own figure is a 90% fall at wholesale — and its chief executive drew the conclusion that factory-made stones are diverging in value from natural ones. If you are weighing a lab-grown diamond, that is an argument you should hear in full rather than a talking point to be spun.
Here is the honest version. The same collapse that made Lightbox unviable is the reason a complete one-carat lab-grown solitaire can start around $1,049 today rather than several times that. Falling input prices are excellent for the person buying a ring and terrible for anyone hoping to resell one. Treat a lab-grown diamond as a purchase, not as an asset, and the decision becomes straightforward.
Bottom line: buy it because you want to wear it. What holds up over time is the workmanship, the certification and whether the seller is still there in year ten.
If you already own a Lightbox piece
Two things are worth knowing. The stone is a real lab-grown diamond and nothing about the closure changes what is on your hand. Lightbox originally sold without independent grading reports and later provided downloadable GIA batch quality verification, which checks a production batch rather than your specific stone — so if you want per-stone grades for insurance, an independent laboratory would need to grade it now.
On warranty, we will not speculate. In May 2025 De Beers said customers would continue to receive support for existing purchases, warranties and after-sale care during the closure process. That sentence was scoped to the closure process and we have found nothing establishing the position in August 2026. The right move is to contact De Beers directly and get the answer in writing rather than to rely on any retailer’s summary, this one included.
Bottom line: your diamond is fine; your paperwork and your after-sale cover are the two things to check.
Four Places To Buy Instead
1. Rare Carat
Closest on priceIf what you liked about Lightbox was the entry price, this is the nearest replacement trading today. Over 1.5 million listed lab-grown stones, colour running from D to K, and reports from GIA, IGI or GCAL available as a filter — which is more paperwork than Lightbox ever offered. Stock is drawn from vetted wholesale supply, but Rare Carat itself is the seller on record, so a refund or a warranty claim goes back to the business that took your money. Resizing runs a full year. It ships only within the United States and Canada.
2. Brilliant Earth
Closest on seeing it in personLightbox was stocked by physical jewelers, which is how a lot of its buyers first handled a lab-grown stone. Brilliant Earth is the straightforward replacement for that: showrooms across the country, both natural and lab-grown inventory if the decision is still open, and grading across several laboratories including GIA. Free resizing runs through the first year on most rings, which is the longest window among the four here.
3. MiaDonna
Closest on peace of mind after you buyBuying from a brand that then disappears is a particular kind of unpleasant, and it makes the return window matter more than usual. Their published window runs 60 days from the day the parcel leaves, at no cost, with no restocking fee, and it holds for international orders too. Lab-grown has been the only thing they sell since 2005, and the company carries Certified B Corporation status. The gap to know about is that they name no grading laboratory on their public pages, so ask before ordering.
4. Beyond Carat
Closest on knowing exactly what you are gettingOurs, so weigh it accordingly. Lightbox’s appeal was that you did not have to learn the 4Cs to buy confidently — the price was flat and the decision was simple. We answer the same instinct from the other direction: instead of removing the grades, we fix them. Every diamond is D, E or F colour, VVS or VS clarity and Excellent cut, graded by IGI with the report in the box, so there is no bad choice inside the range. Rings are made to order in the NYC Diamond District with Regular, Express and Next-Day production, the return window is 30 days from the date your order ships, with a free prepaid, insured UPS return label on U.S. orders, shipping is free worldwide, and the warranty is a lifetime manufacturing warranty. Complete one-carat solitaires start around $1,049. What we cannot offer: Lightbox’s price, a store to walk into, a GIA option, or a parent company anybody has heard of — we are independent, women-led, and carry 43 Trustpilot reviews as of August 2026.
Which Replacement Fits You
You are replacing the price if…
- The $500 entry point was the reason Lightbox was on your list
- You are happy to choose your own grade rather than have one chosen for you
- You are shopping inside the US or Canada
- Rare Carat is the closest answer, and we are not it
You are replacing the simplicity if…
- Flat pricing appealed because it meant no research
- You want the grades settled before you arrive rather than filtered afterwards
- You want a per-stone report rather than a batch verification
- You want a warranty that outlives the first month
Our read: most Lightbox buyers were not really buying De Beers. They were buying a decision that had already been made for them. Whichever brand you pick next, the thing to look for is not the lowest number — it is whether the seller has committed in public to what you will actually receive, and whether that commitment survives the first year.
Frequently Asked Questions
No. De Beers announced its intention to close the business on 8 May 2025, consumer operations were due to stop by that summer, and lightboxjewelry.com served the platform message This store is unavailable when we checked it on 19 August 2026. There is no storefront, catalogue or checkout.
Its own announcement gives the reason: lab-grown diamond prices in the jewellery sector had fallen 90% at wholesale and were tracking closer to a cost-plus model. Lightbox lost $101.3 million in 2023 against $22.3 million in 2022. De Beers framed the exit as a return of focus to natural diamonds.
We cannot tell you, and we will not guess. What De Beers said in May 2025 was that customers would continue to receive support for existing purchases, warranties and after-sale care during the closure process. Whether that still applies now is not something any source we found establishes. Contact De Beers directly.
On headline price, yes. Its 2023 engagement ring range started at $500 for a complete ring and its standard stone tier was $800 per carat. At the Lightbox Finest grade — VVS clarity in D, E or F colour, which is the band we sell — the stone alone was $1,500 per carat, so a plain one-carat Finest ring worked out well above our $1,049 entry.
Not originally. Lightbox launched on the position that its stones did not need independent grading, and later supplied downloadable GIA batch quality verification — a batch-level check rather than a report on your individual stone. If you own one and want per-stone grades, an independent laboratory would have to grade it now.
It means the price of the rough collapsed, which is why complete one-carat lab-grown solitaires can start around $1,049 today. Treat a lab-grown diamond as a purchase rather than an investment. What holds value in a ring is the workmanship, the certification and the warranty behind it.
