Black Friday falls on November 27 in 2026, followed by Cyber Monday on November 30. If you are planning a proposal, use those dates as shopping checkpoints rather than guaranteed production or delivery deadlines.
The best offer is the one that lowers the cost of the ring you actually want. We compare jewelers and their available promotions below; a setting sale, loose-diamond discount and gift with purchase can have very different effects on your budget.
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.
Current deals at a glance
There are no confirmed Black Friday offers here right now. You can still compare these current promotions. One highlighted offer per jeweler; the full list includes the others.
Add the center diamond, setting and any design changes before comparing offers. A large percentage off the setting may make a modest difference to the complete ring, while a lower-priced diamond can save more without a coupon.
Match the diamond shape, carat weight, color, clarity and grading report. Our one-carat and two-carat price guides help put the center-stone price in context. Lab-grown diamonds' lower cost compared with mined stones is not itself a Black Friday saving.
Our ratings reflect our editorial reviews. We may earn a commission from some links.
Choose the ring before chasing the promotion
Online shopping lets you compare diamond details and settings at your own pace. Use a jeweler's consultation if you need help with proportions or how a setting will look, but keep your partner's preferences and your budget in charge.
With Clarity is worth comparing for custom engagement rings and design previews; Ritani is a useful starting point for the loose-stone price. Grown Brilliance, Blue Nile and Brilliant Earth offer different design and shopping strengths. The seller summaries above and our engagement-ring buying comparison explain those differences.
Check the proposal timetable
Ask about the exact ring, size and metal before paying. A stock setting may still need its diamond set, and engraving or a custom design can change the production time. Check resizing and return terms separately from the advertised delivery estimate.
What happened to James Allen's ring sales?
James Allen is now a collection at Blue Nile, not a separate current jeweler. Look at the collection through Blue Nile and check whether the current promotion covers your chosen setting. Our James Allen review retains our earlier shopping experience and explains the transition.
More ways to compare
Browse the main Black Friday guide for other jewelry, or the early-sale guide if you want to buy before the weekend. Waiting for Cyber Monday does not guarantee a cheaper version of your chosen ring.
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.
Buying diamond jewelry for Black Friday
Compare the complete ring or piece of jewelry, including the setting. A large setting discount may make little difference if the center diamond costs more.
