• Taylor Swift and Travis Kelce announced their engagement in a joint Instagram post, with Swift’s publicist confirming the center stone as an old‑mine brilliant cut.
• The ring was co‑designed by Kelce with Kindred Lubeck of Artifex Fine Jewelry; experts describe an elongated antique cushion estimated at roughly 7–10 carats, with values spanning from the hundreds of thousands to around $1 million depending on quality.
• Jewelers report immediate demand spikes for antique styles, including a Page Six–cited surge of nearly 10,000% in searches for old‑mine cuts, making it the most searched diamond cut this month.
• Retailers moved quickly to commercialize the look, with Michael Hill releasing a lab‑grown, elongated cushion option in 2‑ and 5‑carat versions at lower price points.
• Industry voices say the choice is influencing the natural versus lab‑grown conversation, even as some experts note the stone could be a modern cut in the old‑mine style and others highlight ongoing consumer interest in accessible lab‑grown options.
