Liori Diamonds vs Brilliant Earth
Two very different New York and national businesses, both able to put a GIA report on a lab-grown diamond. Here is what each one publishes about grading, returns and warranty — and where we fit, honestly.
Liori Diamonds sells GIA-graded lab-grown diamonds and Brilliant Earth grades across several laboratories, so either can put a GIA report in your hand. Beyond Carat, the third option on this page, is IGI-only and cannot. Pick Liori for GIA plus a Fifth Avenue counter, Brilliant Earth for scale, Beyond Carat for a fixed D–F, VVS–VS band.

Every Liori row above is quoted or summarised from Liori’s own published pages, checked August 2026. Brilliant Earth rows are deliberately sparse: we only print what we have read on a primary source, and we have not re-verified their showroom count or review base for this page. No competitor price is printed above; where we quote a figure elsewhere it is one the brand publishes about itself, because lab-grown listings move weekly. Beyond Carat is not affiliated with either brand. Spot something outdated? Tell us and we’ll fix it.
Which One, and When
Where Liori Diamonds wins
- A GIA report on a lab-grown stone, sold as a live collection rather than as a special request
- A Manhattan counter at 580 Fifth Avenue with published weekday hours and walk-ins welcomed
- A trade-in credit of up to 100% of what you paid, excluding sale items
- Loose stones, moissanite and coloured gems alongside the lab-grown range
- A longer trading record: BBB records Liori as in business since June 2006
Where Brilliant Earth wins
- Scale — the widest inventory of the three, and the only national showroom network
- Several grading laboratories available rather than one
- The natural-diamond option, if you have not settled that question yet
- A far larger public review base than either of the other two
- Sourcing and sustainability programmes with published standards behind them
Where Beyond Carat wins
- One published return window — 30 days from the ship date — not two that disagree
- A free prepaid, insured UPS return label on U.S. orders, with no restocking fee
- A fixed floor on every stone: D, E or F colour, VVS or VS clarity, Excellent cut
- Free worldwide shipping, with U.S. orders insured and signature-required
- A lifetime manufacturing warranty covering defects in materials and workmanship
Our read: if the GIA name on the report is non-negotiable, stop reading here and go to Liori or Brilliant Earth — we cannot serve you and pretending otherwise would be useless to you. If what you actually want is a known grade floor and a return policy that says one thing, that is the case for us.
What Each Brand Publishes
Grading: the question the query is really asking
Liori’s buyer-protection post states plainly that each stone comes with a GIA or IGI grading report, and their live GIA-graded lab-grown collection ran to 98 products when we checked, every one of them a lab-grown ring. Individual listings name the centre stone that way too. One wrinkle worth reading for: on at least one listing the ring’s own certificate field records a different appraiser from the one that graded the stone, so check both fields rather than assuming they match.
Brilliant Earth grades its lab-grown inventory across more than one laboratory, which is why the GIA answer for them is “sometimes, depending on the stone” rather than a blanket yes. Filter for it before you fall in love with a listing.
Beyond Carat has no third answer to offer here. We are IGI-only, at every carat size, and the report travels in the box. If you have been told GIA is the stricter house, that is a legitimate reason to buy from one of the other two.
Bottom line: two of the three can hand you a GIA report; we cannot, and we say so before you spend an hour on the rest of the page.
The grade band underneath the report
A report tells you what the stone is. It does not tell you what the seller stocks. Across the 95 GIA-graded lab-grown rings Liori’s storefront returned, colours ran E, F and D for the large majority but reached down to G and one H, and clarity ran mostly VS1 and VVS2. Their loose lab inventory goes further, down to SI1 clarity and a Very Good rather than Excellent cut grade.
That is not a criticism — a wider band is how a seller offers more choice at more price points, and plenty of buyers are better off with it. It is simply a different product from a fixed floor. Beyond Carat stocks D, E or F colour, VVS or VS clarity and Excellent cut and nothing outside that, which is why our complete 1-carat solitaires start at around $1,049 rather than lower.
Bottom line: compare the band, not just the laboratory name. A GIA report on a G/SI1 stone and an IGI report on an E/VVS2 stone are not the same purchase.
Returns, and a contradiction worth knowing about
Liori publishes two different return windows on its own site at the same time. The refund policy says 14 days from the date of receipt and applies a 15% restocking fee to sized rings; the terms and conditions page says 30 days with a full money-back guarantee; the page they call “The Liori Advantage” carries both statements together, alongside both “no re-stocking fees or penalties” and the 15% sized-ring fee. Liori’s own blog acknowledges the discrepancy. We are not calling it a trick — sites drift — but if you buy there, get the window confirmed in writing first. Who pays for the return journey is not stated anywhere we could find.
Beyond Carat runs one window: 30 days measured from the date your order ships, with a free prepaid, insured UPS return label on U.S. orders. Conditions apply and they are listed on our returns page rather than spread across three.
Bottom line: the number of days matters less than whether the seller publishes one number. Read the refund policy, not the marketing page.
Who wrote the comparison you are reading
The reason this query is hard to answer is that almost every result for it was written by one of the two brands. Liori hosts a dedicated head-to-head against Brilliant Earth on its own blog, in which it claims Brilliant Earth charges 15–25% more for a comparable stone, takes four to eight weeks for custom work against Liori’s ten business days, and offers 60 days of free resizing against Liori’s single free sizing. Every one of those figures is a claim by one competitor about another, on a page built to sell rings, and Liori publishes no lead time on its product pages or in its FAQ to back the ten-day figure.
Brilliant Earth does the same thing in the other direction, hosting its own head-to-head pages against rival brands. That is not scandalous; it is what brands do. It is simply the reason a neutral page has room to exist here, and the reason this one restricts itself to policy documents you can open yourself.
Bottom line: weight a refund policy over a comparison table, whoever built the table — including us.
Where each one is physically
Liori’s counter sits at 580 Fifth Avenue, 31st floor, in the tower on the corner of 47th and Fifth that anchors the New York Diamond District, with published weekday hours and an explicit welcome for walk-ins, plus a stated Florida presence. Brilliant Earth runs a showroom network across the country. Beyond Carat works at 62 W 47th St in the Diamond District itself, but we do not take in-person appointments — the address is where the rings are made, not a place to try them on. Our version is a free 30-minute video or phone call with no obligation.
Bottom line: if handling the stone before you pay is part of your decision, two of these three can do that and we cannot.
Frequently Asked Questions
Yes. Liori runs a dedicated GIA-graded lab-grown collection, and their own buyer-protection post states that each stone comes with a GIA or IGI grading report. Individual product pages name the centre stone as a GIA-graded lab-grown diamond. Their ring paperwork can differ from the stone report, so read both fields on the listing.
They are different laboratories applying their own standards, and IGI grades the large majority of lab-grown diamonds sold worldwide. GIA carries the older name. The practical difference is narrower than the marketing suggests, and we set out both sides on our IGI vs GIA page rather than re-arguing it here.
Liori publishes two different answers. Their refund policy says 14 days from the date of receipt, with a 15% restocking fee on sized rings. Their terms and conditions say 30 days. Their own advantage page carries both statements at once. Ask them to confirm in writing before you order.
Both. Liori has a New York counter at 580 Fifth Avenue, 31st floor, where walk-ins are welcomed and weekday hours are published, plus a stated Florida presence. Brilliant Earth runs a national showroom network. Beyond Carat has neither, offering a free 30-minute video or phone consultation in place of a counter.
No. Beyond Carat is IGI-only at every carat size, and the IGI report ships in the box. If a GIA report is the thing you will not compromise on, Liori and Brilliant Earth can serve you and we cannot. That is a real reason to buy elsewhere and we would rather say so.
Treat it as a claim, not as a finding. Liori publishes its own head-to-head against Brilliant Earth, and Brilliant Earth publishes head-to-heads against its own rivals. Both are marketing documents. Policy text on a refund or warranty page is far more reliable than a number in a comparison table either brand wrote.
