Inside the 18 Most Expensive (and Impressive!) Celebrity Engagement Rings of 2025

Here at Cosmo, our fascination with celebrity engagement rings is infinite. From their cuts, to their sizes, to their costs, we love to know eeeevery detail—and let me tell ya, 2025 has been a fantastic year for ogling A-list diamonds. We kicked off the year with Zendaya’s timeless cushion-cut ring, which was followed by Taylor Swift’s mammoth brilliant-cut old-mine diamond, and we closed out 2025 with Miley Cyrus’ on-trend cushion-cut stone with its chunky 14-karat yellow gold band. And you better believe there were plenty of stunners in between.

Now that the new year is almost upon us, let’s take a minute to revisit some of the biggest, blingiest, most talked-about celebrity engagement rings of 2025 so far—because who knows, another celeb could surprise us with a ring before the year is up! And while you’re here, be sure to check out all the celebrity engagements you may have missed this year (as well as Cosmo’s favorite celeb couples of the year). Happy snooping!
