Overview

• Swift shared engagement photos on Aug. 26, including a close-up of the ring on Instagram.
• TODAY.com confirms the ring was designed by Kindred Lubeck of Artifex Fine Jewelry.
• Jewelers identify the center stone as an old mine or brilliant cushion cut with vintage details such as an engraved thick gold band and a prong-and-button-back setting.
• Estimates based on photos range from roughly 7 to 15 carats, with valuations from about $400,000 to around $1 million depending on the stone’s specifics.
• Observers point to preexisting momentum for antique stones and note that natural old mine diamonds are scarce—with hallmarks like an open culet—suggesting stronger demand and potential price pressure.
