Diamond deals
Find Valentine's engagement-ring offers and compare the diamond, setting, delivery and resizing terms before choosing a proposal ring.
Valentine's Day is February 14, with the next occasion on February 14, 2027. Start choosing the ring well before the sale deadline: a custom setting, diamond inspection, resizing or engraving can affect when it is ready.
We compare available jeweler offers below. Where Valentine's promotions have not been confirmed, current general deals are labelled separately so you can still compare prices without relying on last year's codes.
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.
There are no confirmed Valentine's Day offers here right now. You can still compare these current promotions. One highlighted offer per jeweler; the full list includes the others.

A lower setting price can be outweighed by a higher diamond price, particularly at larger carat weights. Compare similar shapes, weights, color and clarity grades, and read the grading report.
Use our diamond price guides and engagement-ring seller comparison to narrow the search. Spend on the features you can see and the design your partner wants rather than increasing the budget to qualify for a gift.

Find out the preferred diamond shape and metal if you can. A ring your partner already wears may help with style, but its size is only useful if it fits the intended finger. Check resizing terms before ordering, particularly for eternity designs or rings with diamonds around the band.
Comparing online lets you take your time with the stone and setting. Ask for help if you cannot judge how the combination will look. Our With Clarity review describes our ring purchase and its design-preview approach; the seller profiles above explain the other options.
Use the estimate for the complete ring in the correct size, not just the loose diamond or a general sitewide shipping claim. If the date is fixed, ask the jeweler to confirm the schedule before you pay. Leave room for a second choice if the first ring cannot arrive in time.
James Allen is now a collection at Blue Nile. Compare the current collection and Blue Nile's promotion terms instead of relying on old James Allen coupons. Our James Allen review explains the change.

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.
Choose the style your recipient will wear, then compare prices. For a surprise ring, check resizing and returns before ordering, especially if you add engraving.
