Pop superstar Taylor Swift and Kansas City Chiefs tight end Travis Kelce disclosed their engagement on Tuesday in a joint Instagram post that showed Kelce kneeling in a rose-filled garden. The pair, both 35, have been publicly dating since 2023, when Swift began attending Chiefs games and Kelce made repeated references to her on his "New Heights" podcast. Swift’s ring is an antique-style old mine brilliant-cut diamond set in yellow gold and designed by New York jeweler Kindred Lubeck of Artifex Fine Jewelry. Jewelry specialists estimate the stone at roughly 8–10 carats—some place it as high as 13—and value the piece at between $650,000 and more than $1 million. Meta said the announcement amassed about 14 million likes within a little more than an hour, ranking among the fastest-growing posts in Instagram’s history. Congratulatory messages arrived from NFL teammates, celebrities and even President Donald Trump, who paused a Cabinet meeting to say he thought both Swift and Kelce were “terrific” and wished them “a lot of luck,” a markedly softer tone after months of criticism of the singer. The so-called Swift effect rippled through financial markets: shares of Signet Jewelers ticked higher and Brilliant Earth Holdings surged roughly 20% on expectations of heightened demand for engagement jewelry. Brands and broadcasters also pivoted coverage to the celebrity news, underscoring the commercial pull of the couple’s expanding profile.
