We recommend Blue Nile for its jewelry craftsmanship and well-rounded buying experience. A promotion can make a favorite design more attractive, but we would still compare the diamond price and complete piece before buying.
The offers below are from Blue Nile only. James Allen is now a collection at Blue Nile, so check the current promotion's exclusions if you are choosing one of those designs.
Affiliate disclosure
Some retailer links may be affiliate links, and LabGrownCarats may earn a commission if you buy through them. Source links may be untracked. Compensation does not determine our verdicts, test results, or the evidence we report.
Deals at a glance
Check the offer's spending requirement and exclusions before choosing your jewelry. One highlighted offer; see the full list below for any others.
Separate loose diamonds, settings and finished jewelry when comparing offers. A discount on the setting does not reduce the diamond by the same percentage. Add both to see what the complete ring costs.
For a necklace, include the chain. For studs, compare the carat weight for the pair, metal and backing type. Our Blue Nile review explains the buying experience and where we think another jeweler may offer better value.
Our ratings reflect our editorial reviews. We may earn a commission from some links.
When should you shop Blue Nile's sales?
Use the available offers above as your guide to what you can use now. Black Friday, Christmas and other gift occasions can be useful times to compare jewelry, but an old sale calendar is not a promise of the next discount.
If you have found a particular design, save its details and price before deciding to wait. A later sale matters only if it applies to the piece you want and leaves enough time for delivery.
James Allen collection offers
Do not assume a former James Allen code will work at Blue Nile. Check the offer against the collection item in your basket. Our James Allen review explains the move and retains our earlier shopping experience.
Gifts and complete-ring prices
A gift with purchase should not decide the ring or jewelry for you. If your planned order already qualifies, it can be a welcome extra. Otherwise, compare the cost of the additional spend with what the gift is worth to you.
For a loose lab-grown diamond, use our price guides as a separate comparison. Blue Nile's design and service strengths can matter, but a sale label alone does not establish the lowest price.
How we choose offers
Our jeweler ratings and recommendations come from the research and purchases described in the linked reviews. Offers are checked separately: we show the spending requirement and end time when available, and link to the seller's full terms. An advertised saving is not proof of a historical low. We do not reuse expired codes or assume future holiday promotions have been announced.
