Taylor Swift Debuts 10-Carat Antique Diamond Engagement Ring at iHeartRadio Awards

When Taylor Swift stepped onto the red carpet at Hollywood's Dolby Theatre on March 26, the conversation didn't start with her seafoam green corset and jeweled-fringe skirt, or even with her record-setting seven awards. It started with her left hand.

The engagement ring Swift wore to the 2026 iHeartRadio Music Awards made its first major red carpet appearance since Travis Kelce's August 2025 proposal, and it delivered every detail jewelry watchers had been anticipating since the couple's Instagram reveal. Designed by Kindred Lubeck of New York's Artifex Fine Jewelry, with Kelce as a direct collaborator in its creation, the ring centers on an old mine brilliant-cut diamond in an elongated cushion shape, estimated by multiple experts at approximately 10 carats. Natural Diamond Council editor Grant Mobley valued the stone at around $750,000, citing its "exceptionally high clarity and such a rare, unique cut," with broader estimates ranging from $500,000 to over $1 million.

The old mine cut predates mechanized diamond-cutting techniques, shaped by hand during an era when each stone's proportions were guided as much by the craftsman's eye as by geometry. The result is a diamond with a higher crown, a smaller table, and a larger culet than its modern equivalents, producing a softer, warmer light that no contemporary brilliant exactly replicates. The stone is set in four prongs with a button back, a small bezel cradling the base of the diamond that adds an extra layer of security and visual grounding. The mounting is yellow gold, hand-engraved throughout.

Lubeck, who worked with Kelce directly on the design, is a goldsmith, hand engraver, and vintage jewelry collector. On her Artifex Fine Jewelry platform, she describes her practice as making "hand-engraved jewelry made with natural and captivating gemstones." That philosophy is legible in every element of Swift's ring: the warm metal choice, the antique cut, the engraving that distinguishes the band from anything machine-finished. Lubeck has since partnered with Sotheby's on a capsule collection showcasing bespoke rings set with antique-cut stones, with bidding running through November.

Swift arrived alongside Kelce for what marked their first awards show appearance together. She accessorized with a Spinelli Kilcollin tennis bracelet, a Nak Armstrong ear cuff, a Selim Mouzannar ring, and 18-karat yellow gold, diamond, and tourmaline drop earrings by Dena Kemp. The jewelry palette stayed entirely consistent: warm metals, antique sensibility, no attempt to compete with the ring's presence.

Swift won seven prizes on the night, including Artist of the Year and Pop Album of the Year for "The Life of a Showgirl," setting a record for the most awards won by a single artist in one evening at the ceremony. She is now the most-awarded musician in iHeartRadio Awards history.

Since the engagement's August 2025 reveal, jewelers have reported a notable increase in client requests for hand-engraved bands and antique-cut center stones. One jeweler noted that old mine diamonds "send a signal that the wearer values individuality over mass-produced perfection." The iHeartRadio red carpet only amplified that signal, giving the ring its most visible platform yet and placing Lubeck's work squarely at the intersection of pop culture and fine jewelry craftsmanship.
