Here at Cosmo, we simply can’t get enough of celebrity engagement rings. From their cuts, to their sizes, to their costs, I love to know eeeevery detail—and let me tell ya, 2026 has been a fantastic year for ogling A-list diamonds, from Zoë Kravitz’s massive elongated cushion-cut sparkler to Dove Cameron’s gorgeously unique Asscher-cut diamond.
Now that we’re over halfway through the year, let’s take a minute to revisit some of the biggest, blingiest, most talked-about celebrity engagement rings of 2026 so far—though you better believe I’ll be adding to this list before the year is through. Happy snooping!
