Swift’s old mine brilliant cut diamond ring is estimated to be 7 to 10 carats
Swift’s engagement ring boasts a massive old mine brilliant cut diamond, a rectangle-cut diamond with antique references. The ring — which is estimated by Angelic Diamonds’ Neil Dutta to be between 7 and 10 carats — appears to be a bezel setting, meaning it wraps around the centre stone. The main diamond is flanked by “half-moon plus … small round” side jewels, which give it “vintage” feel, per Jared Jewellers’ VP of Merchandising Ann Grimmett.
The ring is estimated to cost between $3.5 and $5 million
Swift and Kelce announced their engagement in a joint Instagram post on Aug. 26 2025 , sharing several sweet photos from their floral-filled garden proposal.
The singer then re-posted the carousel to her Instagram Stories, attaching her hit song, “So High School,” which Swifties have long theorized she wrote about her relationship with the football player.
We truly happy for this couple!
