On August 26, 2025, Taylor Swift and Travis Kelce posted five photos to Instagram with a caption about an English teacher and a gym teacher getting married. Within hours the internet had zoomed in on the third slide — a close-up of a chunky, glowing diamond set low in a hand-engraved yellow gold band — and jewellers around the world started fielding the same request: "I want the Taylor Swift ring."

One year later, the couple are married, and the ring has done something very few celebrity rings manage. It didn't just trend for a week; it pulled an entire antique cutting style back into the mainstream. This guide covers everything that's actually known about the ring, then walks through how to recreate it with an old mine cut lab grown diamond ring or moissanite.

The ring at a glance

What is an old mine cut diamond?

Swift's publicist confirmed just one technical detail: the diamond is an old mine brilliant cut. Everything else — carat, colour, clarity, price — has been estimated by jewellers studying the photos. That one confirmed fact matters most, because the cut is what gives this ring its entire personality. (For the technical background, see the GIA, the industry's grading authority.)

The old mine cut dates to the 1700s and dominated through most of the 1800s, before electric light or precision cutting. Cutters shaped each stone by hand, which is why old mine cuts have:

• A squarish, cushion-like outline with softly rounded corners
• A high crown — the top half of the stone sits tall above the girdle
• A small table, noticeably smaller than on a modern brilliant
• A large, open culet, visible as a small dark circle from above
• 58 large, chunky facets instead of many small, precisely angled ones

Because these stones were cut to sparkle under candlelight, they throw broad, slow flashes of light rather than the fast glitter of a modern cut. Less disco ball, more glowing ember.

Old mine cut vs. old European cut vs. modern cushion

Swift's diamond is usually described as an elongated cushion: slightly longer than wide, which reads as both vintage and flattering on the finger. See our elongated cushion cut rings for the modern version of the shape.

How many carats is Taylor Swift's engagement ring?

No official carat weight has been released. New York estate jeweller Benjamin Khordipour estimated the stone at around 8 carats shortly after the announcement, and several outlets have since reported it as 10 carats.

Old mine cuts are notoriously hard to size from photos. The crown is tall and the stone is deep, so much of the weight sits below the girdle. An 8-carat old mine cut often looks smaller face-up than an 8-carat modern cushion, which is exactly why estimates vary. Unsure what size suits you? Read our carat size guide.

How much does Taylor Swift's engagement ring cost?

The most widely cited estimate puts the ring at $550,000 to $750,000, with some valuations higher. Three things drive that price:

1. The stone is antique and large. Genuine old mine cuts above 5 carats are rare because so many were re-cut into modern brilliants during the 20th century.
2. The setting is entirely handmade. Lubeck hand-engraves every piece; nothing is cast from a mould.
3. The style is now famous, which raises the cost of any equivalent piece.

Who designed the ring?

Kindred Lubeck, founder of Artifex Fine Jewelry in New York. She is the daughter of Florida goldsmith Jay Lubeck, learned the trade in his workshop, and opened her own studio in 2024. Her signature is hand engraving — cutting patterns directly into the metal with small gravers, a technique she has compared to tattooing a ring.

The best detail came from Swift herself. About a year and a half before the proposal, she had shown Kelce a video of Lubeck's work because she thought it was cool. He said nothing, remembered it, and worked with Lubeck to design the ring. When Swift saw it, she recognised the engraving immediately. The ring wasn't just expensive; it was specific.

Why the bezel setting matters

A bezel wraps a thin rim of metal around the entire edge of the stone instead of holding it with prongs. For decades it was considered a practical choice, not something for a 10-carat showpiece. On Swift's ring, the bezel frames the stone in warm gold, protects the irregular edges of an antique cut, and keeps the profile low so a very large stone still feels wearable every day.

Yellow gold is back

Antique diamonds often carry slightly warmer colour grades that look better in yellow gold than in white metal, where the tint reads as a flaw instead of a feature. If you're recreating this look, this is the one place not to compromise. Our yellow gold engagement rings are made in 14k and 18k.

Lab-grown diamond or moissanite for this style?

Lab-grown diamonds are chemically and optically identical to mined diamonds. Because they are grown to order, cutters can shape them into true antique cuts. A lab-grown old mine cut in the 3–5 carat range gives you the exact visual character of Swift's stone.

Moissanite is a separate gemstone with more fire than diamond, which suits the old mine aesthetic well, and it holds up to daily wear for a lifetime. If you want the scale of the original — 5, 6, even 8 carats — this is the route. For the full breakdown, read lab grown diamond vs moissanite.

The story behind the ring

Kelce first tried to meet Swift in 2023 by bringing a friendship bracelet with his phone number to her Eras Tour show in Kansas City, and couldn't get it to her. He talked about it on his podcast, she heard, and by September 2023 she was at Arrowhead Stadium. In August 2025 he proposed in a private garden in Lee's Summit, Missouri. The couple married in July 2026 in a private ceremony in New York.
