Overview

• Taylor Swift and Travis Kelce announced their engagement on Instagram, and Swift’s publicist Tree Paine confirmed the ring’s center stone as an old mine brilliant cut.
• The ring was designed with Kindred Lubeck of Artifex Fine Jewelry, and jewelers estimate an elongated antique-style cushion of roughly 7–10 carats, though some experts say it may be a modern stone cut in the old-mine style.
• Search interest exploded after the reveal, with Lorel Diamonds reporting nearly a 10,000% overnight jump for old mine cuts, now topping monthly diamond-cut searches.
• Retailers moved quickly, with Michael Hill releasing lab-grown elongated-cushion ‘inspired’ rings in 2ct and 5ct options priced at $7,999 and $18,999, while jewelers report a surge in inquiries for antique cushions.
• Valuation remains unsettled, with expert estimates ranging from around $120,000 to more than $1 million, as coverage renews focus on natural versus lab-grown diamonds and reports note share-price gains for Signet Jewelers and Brilliant Earth following the news.
