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 others 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.

Jared MALL CHAIN

Signet's upper mall brand. Bigger stores, bigger stones, on-site workshops.

Angara COLOUR

Coloured stones. Sapphire, emerald and ruby as the centre stone rather than as an accent.

Trading since 2005 · Independent
1stDibs ESTATE

Estate and vintage. The only route here to a ring that already exists rather than one being made.

Trading since 2001 · 1stDibs (NASDAQ: DIBS)

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
Zales vs Kay — one company, two mall counters
Brilliant Earth vs VRAI — whose sustainability claim can you actually check
Rare Carat vs Blue Nile — aggregator or retailer

Lab-grown vs natural — same material, very different resale

Selling a diamond — what you will actually be offered

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.

The mall chains

Signet Jewelers owns Kay, Zales, Jared and Blue Nile. None of them mentions it. Helzberg belongs to Berkshire Hathaway, which matters more than it sounds when a guarantee says lifetime. Shane Co is the last large US chain still family owned.

The specialists

Each of these does one thing the others do not. VRAI grows its own diamonds at a hydroelectric-powered foundry, which is why its sustainability claim is checkable where most are not. With Clarity posts replica rings so you can try the design at home. Clean Origin answers the risk of buying online with a return window several times the category standard. Angara is for when the answer is a sapphire rather than a diamond. 1stDibs sells rings that already exist.

Beyond the chains: Ritani ships your ring to a local jeweller so you can see it before paying, Costco publishes a minimum quality standard almost nobody quotes, and Whiteflash sells on the one grade that decides how a diamond actually looks.

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.
