Independent deals guide
Considering a Kay Jewelers sale? Compare complete diamond jewelry prices, specifications and current offers from the online jewelers we recommend instead.
We would compare Kay's final price with other jewelers before buying, even when the advertised discount is large. Kay is not one of our main lab-grown diamond recommendations, and we do not have a verified Kay promotion to list here.
The overview and full offer list below show deals from the alternatives we recommend, not Kay offers. Use them to compare the cost of similar jewelry alongside the Kay piece you are considering.
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.
These offers are from jewelers we recommend as alternatives to Kay Jewelers. They are not Kay Jewelers promotions. Compare similar jewelry and the complete price. 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 moreMatch the metal, diamond quality and total carat weight before comparing jewelry. For a ring, include the center diamond and setting. For earrings, confirm whether the advertised weight describes the pair. Two similar photographs can hide quite different specifications.
An “up to” saving is not the discount on every piece. Compare the final price of the item you want with a similar item elsewhere, and read any exclusions before counting the saving.

Check Kay's own current terms if you have a particular piece in mind. An older Black Friday, Christmas or Valentine's code does not establish the offer available today. We have removed old sale claims from this page rather than presenting them as current discounts.
Online sellers can make it easier to compare individual diamond specifications and complete prices. Ritani is a useful starting point for a loose stone, while With Clarity, Grown Brilliance, Blue Nile and Brilliant Earth offer different ring and finished-jewelry strengths. The seller summaries above explain those differences.
Our recommended jeweler comparison helps narrow the choice. If you prefer buying in a store, include the value of seeing a design and getting in-person help in your decision, but still compare the actual jewelry.
Set the total budget before looking at a monthly payment. Compare the full amount payable and read the payment provider's terms. A smaller monthly figure does not make a more expensive piece a better deal.
Check the exact item's delivery, sizing and return conditions before paying. A convenient sale date is less important than getting the right piece in time and having useful options if it does not fit.
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.
