Returns and resizing, compared
All four advertise a free return window. The windows differ, the clock starts in a place that catches people out, and the exclusions are where the actual risk sits.
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.

Blue Nile's clock starts at shipment, not delivery
This is the detail most worth knowing and the one most often reported wrongly, including in earlier versions of this page.
Blue Nile's policy states 30 days from the shipment date. Transit comes out of your window before the box reaches you: a parcel that takes four days to arrive leaves twenty-six, not thirty. James Allen and Brilliant Earth both state 30 days without naming the trigger on the pages we read, so ask before you buy rather than assuming delivery.
In no case does the clock start at the proposal. Order in October for a Christmas engagement and the right has lapsed before the box is opened — at that point you are asking for a goodwill exception, not exercising a right.
If the gap between purchase and occasion exceeds the window, treat the purchase as final, or buy closer to the date and accept the delivery risk instead.
The limits nobody mentions
Blue Nile caps free returns at two per customer per year. After that each insured label costs $30. Nothing on the marketing page says so; it is in the policy.
Lose the grading report and it costs $150. Both Blue Nile and James Allen charge that to have the stone re-graded. On a loose diamond the certificate is part of what you are returning.
Blue Nile gives you five days to report arrival damage. Miss it and the claim gets harder.
Where returns are actually lost
The window is rarely the problem. These are:
Engraving. Blue Nile excludes engraved items from return entirely. Brilliant Earth excludes engraved rings from return while allowing a paid resize within a year. James Allen's policy pages do not exclude them, which is a real difference worth confirming before you engrave. On the policies that do exclude, the right disappears at checkout, in a box that feels like a nice touch rather than a decision.
Resizing. At Blue Nile a resize after purchase removes the item from return eligibility outright, and Brilliant Earth excludes resized rings too. James Allen gives a free resize inside the first year. If the size is uncertain, check which of those you are dealing with before adjusting anything.
Condition. Returned pieces must arrive unworn and undamaged with all documentation, including the grading report. Losing the certificate can complicate a return on a stone worth thousands.
Packaging and carrier. Policies specify how a return must be packed and shipped. Deviating can shift the loss to you if the parcel goes missing, and these parcels are worth stealing.
Marketplaces work differently
Rare Carat aggregates other vendors' inventory, so the return terms come from whoever holds the stone. Two listings on the same site can carry different windows and different exclusions.
That is not a criticism — it is a structural difference, and it means the check happens per listing rather than once. Read the vendor's terms on the specific stone before buying, and do not rely on a general summary.
What we cannot tell you
We have read these policies; we have not put a return through. How a policy behaves in practice — whether a refund lands promptly, how an edge case is treated, whether goodwill is extended — is outside what we can honestly assess. Our methodology sets out that boundary in full.
Common questions
When does the return window start?
Blue Nile runs its 30 days from the shipment date, not from delivery — so transit time comes out of your window before the parcel arrives. James Allen and Brilliant Earth state 30 days without naming the trigger on the pages we read; ask before you buy. In no case does the clock start at the proposal.
Does engraving void a return?
Commonly, yes. Personalised and engraved items are excluded from returns on most of these policies. It is the single most frequent way a buyer loses the right without realising.
Can I return a resized ring?
Often not. Resizing can end the return right on some policies. If you are unsure about the size, return and reorder rather than resize, or confirm in writing first.
How does returning to a marketplace differ from returning to a retailer?
A marketplace passes you to the underlying vendor, whose terms govern and can vary between listings. Check the specific vendor's policy on the specific listing, not the marketplace's general summary.
