Diamond deals
Compare engagement-ring sales from our recommended jewelers. Check diamond and setting prices together, with ratings, design advice and proposal planning.
Choose the ring style and a budget you are comfortable with before chasing a discount. You do not need to spend a fixed number of months' salary. A lab-grown center diamond can leave more room for the setting you want, or simply let you spend less.
The overview below highlights available jeweler promotions. Some cover settings or selected jewelry rather than the complete ring, so check the eligible products before counting the saving.
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.
Compare these offers from our recommended jewelers. The final price, diamond quality, and return policy matter more than the size of the discount. One highlighted offer per jeweler; the full list includes the others.

New subscribers or first orders — check terms · Code: WELCOME · Purchase of $1,000 or moreA ring has two main costs: the center stone and the setting. Add both before comparing sellers. A large setting discount can be outweighed by a higher diamond price, especially with a larger stone.
Match the diamond shape, weight, color, clarity and grading report. Our one-carat and two-carat price guides offer a starting point for loose lab-grown stones. Include any metal upgrade, engraving or design changes in the ring total.
A gift with purchase is only an extra. We would choose the ring on its own merits and avoid spending more just to cross a gift threshold.

With Clarity's custom-ring focus and design previews make it a useful starting point when you are deciding on a setting. Ritani is especially useful for comparing the center-stone price. Grown Brilliance, Blue Nile and Brilliant Earth offer different design and shopping strengths; the ratings above explain where each fits.
Our engagement-ring seller comparison goes into more detail about the buying experience.
Online shopping makes it easier to compare diamonds and settings at your own pace. Look beyond the main photograph: check the setting's height, width and how it will sit beside a wedding band. If the diamond has a video, use it alongside the grading report rather than judging by grades alone.
Only if it fits your proposal timetable. Choosing a stone, making the ring and resizing can take longer than a sale weekend. Ask for the arrival estimate for your exact order and check return and resizing terms before paying.
Our Black Friday ring guide covers that occasion. A later promotion is not guaranteed to beat a competitive price available now.
James Allen designs are now sold as a collection at Blue Nile. Our James Allen review explains the change and keeps our earlier ring-shopping experience in context.
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.
