Somebody should read the fine print.
Every major online jeweller says the same four things about itself. We read what they actually commit to in writing — the return clocks, the exclusions, the warranty carve-outs, who owns whom — and publish it with a link to the source, so you can check it yourself.
- We read the published policies, in full, and date them
- We explain who owns whom and why it matters
- We don't print prices — they move daily; the buttons open live listings
- We don't claim to have bought anything
Check live prices — we don't print them here, because they change daily.
Rings
The centre stone is where nearly all the money goes. Compare the same specification at each — shape, carat, colour, clarity, cut grade and grading laboratory held identical, or you are not comparing anything.
Earrings
Sold by total carat weight across the pair, so a 1ct pair is two half-carat stones. Cheap enough to make a sensible first purchase from a retailer you have not used before.
Bracelets
Check the clasp and the safety catch before the stone quality. A tennis bracelet that springs open on the wrist is the most common way people lose one.
Necklaces
The chain matters more than buyers expect. Check the gauge and the clasp — a heavy pendant on a thin chain is a repair waiting to happen.
Links open each retailer's own category page. Rare Carat links are affiliate links and earn us a commission if you buy, at no extra cost to you. The other three are plain links that earn us nothing today; if that changes, this line changes with it. Every relationship is listed on the disclosure page.
The retailers
-
Blue Nile VALUE
The volume player. Largest certified-diamond inventory, keenest pricing on plain settings.

-
James Allen WINDING DOWN
Being retired. Signet announced the site is closing; the name continues as a collection inside Blue Nile.
Trading since 2006 · Signet Jewelers
-
Brilliant Earth PROVENANCE
The provenance premium. Traceable sourcing, showrooms, and a price to match.
Trading since 2005 · Brilliant Earth Group (NASDAQ: BRLT)
-
Rare Carat MARKETPLACE
The aggregator. Searches other vendors' inventory and undercuts on price.
Trading since 2016 · Independent
-
Grown Brilliance LAB-ONLY
Lab-grown only. No natural inventory at all, which is the whole proposition.
Trading since 2021 · Independent — founded by Akshie Jhaveri, a third-generation jeweller
Head to head
Most people arrive here already down to two names. These pages settle it on price, imaging, returns and who actually owns whom.
- Blue Nile vs Brilliant Earth — the value case against the provenance premium
- Blue Nile vs James Allen — one owner, and one of them is closing
- Brilliant Earth vs Grown Brilliance — the lab-grown question
- Rare Carat vs Blue Nile — aggregator or retailer
Before you compare
- The 4Cs without the sales pitch — only one of the four changes what you see
- Which grading reports to trust — and how to verify one in two minutes
- Lab-grown vs natural — same material, very different resale
- How much to spend — where the salary rule came from
- Returns and resizing compared — read from the policies, not the marketing pages
- Financing and store cards — deferred interest is not zero interest
Happening now
Signet is closing jamesallen.com. The company announced in March that it would retire the site and continue James Allen as a collection inside Blue Nile. If you already bought there, your upgrade credit and your free resize allowance are worth an email this week — what to confirm, and where to shop instead.
What this site does
Diamond retail runs on claims that sound identical and terms that are not. Everyone offers free returns; the clocks start in different places. Everyone offers a lifetime warranty; the exclusion lists differ. Two of these four have the same owner and neither mentions it.
So we read the policies — the actual pages, in full — record the date, and write down what they say. When we checked Blue Nile's, we found its 30-day window runs from shipment, not delivery — which contradicts what most sites reporting on it say, and what we had written ourselves. That correction is on the returns page.
We have not bought from any of these retailers and we do not print prices, because a price we published today would be wrong next week. Every review says so in its own words. We earn commission when readers buy through our links; the rates differ and none of them has changed a word here. Read the methodology.
