The Diamond: Cut and Shape Terms
Old Mine Cut
This is the term that launched a thousand Google searches. The old mine cut is among the earliest diamond cuts, originating in the 1700s and remaining popular through the 1800s. It has 58 facets, all cut by hand, which means no two old mine diamonds look exactly alike. The facets are large, blocky, and slightly imperfect compared to the laser-precise symmetry of modern cuts.
What makes an old mine cut distinctive:
- High crown: The upper portion of the stone sits taller, creating a more sculptural profile.
- Small table: The flat top facet covers only about 38-45% of the stone’s width, compared to 66-70% on a modern cushion cut. That’s a dramatic difference.
- Deep pavilion: The bottom half extends further down, giving the stone visible depth.
- Large, visible culet: The tiny facet at the very bottom of the stone is much bigger than on modern diamonds (where it’s often a pinpoint or absent entirely).
- Candlelight sparkle: Instead of the sharp, intense flashes of a modern brilliant cut, old mine diamonds throw broad, warm flashes of light. Jewelers call this a “candlelight glow” because these stones were literally cut to perform in candlelit rooms.
The 58-facet count has generated some fun speculation among Swifties. Some fans have pointed out that 5+8=13, which is widely known as Taylor’s lucky number. Coincidence? Maybe. But knowing the level of thought that went into this ring, probably not.
Elongated Cushion Cut
This is the modern cousin of the old mine cut. An elongated cushion has a rectangular shape with softly rounded corners and a length-to-width ratio that makes the stone look longer on the finger. Most cushion cuts sit around a 1.20 to 1.30 ratio.
Swift’s stone? Estimated at 1.50 or higher. That kind of elongation is exceptionally rare in any diamond, let alone one estimated at 8-10 carats. It’s one of the reasons the ring looks so striking on her hand. The stone practically stretches across her finger.
For anyone shopping, the elongated cushion creates a very flattering look that makes fingers appear longer and more slender. You can explore this shape in a vintage cushion cut moissanite ring that captures the same classic proportions.
Antique Cushion Cut
This is where naming gets confusing, and most articles don’t bother explaining the distinction. An old mine cut IS an antique cushion cut. It’s the antique version of what eventually evolved into today’s modern cushion. So when jewelers say “antique cushion,” they often mean something closer to an old mine cut than to a modern brilliant cushion.
The confusion matters when you’re shopping. If a listing says “antique cushion cut,” check whether it means genuinely old-style faceting (blocky, high crown, visible culet) or just a modern cushion that’s been given a vintage-sounding name. There’s a real difference in how the stone handles light.
Old Mine Brilliant
You’ll see this full term in some of the more detailed coverage of Swift’s ring. “Brilliant” here refers to the faceting pattern, not the sparkle level. A brilliant faceting arrangement means triangular and kite-shaped facets radiating from the center, as opposed to step-cut faceting (like an emerald cut) where facets run in parallel lines.
Every old mine cut is technically an old mine brilliant. The word “brilliant” is just describing the geometry of the facet layout.
Crushed Ice vs. Chunky Faceting
If you’re shopping for a modern cushion cut that captures the old mine feel, this distinction is critical. A “crushed ice” cushion has dozens of tiny, intricate facets that create a shimmering, almost kaleidoscopic effect. A “chunky” or classic cushion has fewer, larger facets that produce a clearer, more geometric sparkle with distinct flashes of light.
Old mine cuts are the original chunky cut. If you want to recreate that look in a modern stone, especially in moissanite, you want chunky faceting. Crushed ice is beautiful, but it’s a completely different aesthetic.
Length-to-Width Ratio
This is the number that describes how rectangular (or square) a stone appears. A 1.00 ratio is perfectly square. Anything above about 1.15 starts to look noticeably elongated.
Swift’s stone at an estimated 1.50+ ratio is genuinely unusual. Most jewelers and vendors who sell elongated cushions stock them in the 1.20-1.35 range. Finding a stone that stretched, especially in a large carat weight, takes serious searching. For anyone looking at an elongated cushion solitaire, ratios in the 1.25-1.40 range are more realistic and still give that beautiful lengthened silhouette.
The Setting: Structure Terms
Bezel Setting
The bezel is the gold rim that wraps directly around the stone, holding it in place. Instead of relying entirely on prongs that sit on top of the diamond, a bezel hugs the stone’s perimeter. It gives the ring a sleek, vintage feel and adds a layer of protection around the edges of the diamond.
On Swift’s ring, the bezel works alongside four corner prongs for extra security. This combination is unusual. Most rings use either a full bezel or prongs, not both. The hybrid approach gives the ring that antique, substantial look while still letting light enter from multiple angles.
Button Back
This is a term even many jewelry professionals don’t use daily. A “button back” is a small secondary bezel that sits behind the main stone, visible from the underside of the ring. NBC News confirmed that Kelce’s ring features this detail. It adds structural integrity and creates a finished, polished appearance when viewed from the side or below, something a lot of engagement rings neglect.
Four-Prong Setting
Prongs are the small metal claws that grip the stone. Four prongs are the most common configuration for cushion cuts because they sit at the corners without obscuring the stone’s shape. On Swift’s ring, the four prongs complement the bezel rather than replacing it.
Solitaire
The overall setting style of Swift’s ring is a solitaire, meaning one center stone without side diamonds or accent stones. The solitaire is the most classic engagement ring format. What makes Swift’s version distinctive is all the detail packed into the band and bezel rather than additional stones.
Hidden Halo
This feature is NOT on Swift’s actual ring, but it shows up constantly in “get the look” versions. A hidden halo is a ring of small diamonds or moissanite stones set underneath the center stone, invisible from the top view but adding sparkle from the side profile. Many people recreating the Taylor Swift engagement ring style add a hidden halo for extra brilliance, especially when using a smaller center stone.
If that appeals to you, a cushion cut with hidden halo captures that concept well.
The Band: Metalwork Terms
18K Yellow Gold
Most modern engagement rings default to platinum or white gold. Swift’s ring bucks that trend with 18-karat yellow gold, and the choice is deliberate. Yellow gold warms an antique stone and lets the diamond’s fire read against a friendlier, more complementary backdrop. White metals can make old mine cuts look slightly cold or washed out.
18K specifically means the gold is 75% pure gold mixed with 25% alloy metals for strength. It’s richer in color than 14K (58.3% gold) but softer, which actually works well for hand engraving since the metal yields more readily to hand tools.
Filigree
The ornamental metalwork along the sides of Swift’s band. Filigree involves delicate, lace-like patterns created in metal, either by bending thin wire or carving into the band itself. On Swift’s ring, the filigree includes what appears to be a small “T” worked into the design, possibly a reference to “Taylor and Travis” or their couple nickname “TnT.”
That kind of hidden personalization is one of the advantages of working with a bespoke jeweler rather than buying off the shelf.
Hand Engraving
This is Kindred Lubeck’s signature technique and one of the reasons Kelce chose her for the commission. Hand engraving means using small handheld tools (called gravers or burins) to physically carve patterns into the gold surface. It’s painstaking, slow work that produces results no machine can replicate. Each cut has slight variation, giving the finished piece an organic warmth that laser or machine engraving simply can’t match.
Lubeck said she became “totally hooked” after taking an engraving class in 2021 and built her entire brand aesthetic around the craft.
Milgrain
While not explicitly confirmed on Swift’s ring, milgrain is a related vintage detail worth knowing. It’s a row of tiny beads along the edge of a band or setting, created by running a special tool along the metal. Milgrain was standard on rings from the Edwardian and Art Deco periods and frequently appears on vintage-inspired engagement rings.
The Stone: Anatomy Terms
Crown and Pavilion
Every faceted gemstone has two main sections. The crown is the upper half, everything above the widest point (called the girdle). The pavilion is the lower half, everything below the girdle that tapers to a point.
Old mine cuts have a high crown and deep pavilion. That combination creates the tall, sculptural profile that distinguishes them from flatter modern cuts. It also means old mine cuts sit higher in their settings, which contributes to that substantial, elevated look on Swift’s hand.
Table
The table is the large, flat facet on the very top of the stone. It’s the window you look through when viewing a diamond from above.
Here’s a number that tells you a lot: old mine cuts have a table that covers only 38-45% of the stone’s width, while modern cushion cuts expand the table to 66-70%. A smaller table means more of what you see from above is angled faceting rather than a flat surface. That’s why old mine cuts scatter light in warm, broad flashes instead of the concentrated brilliance of modern stones.
Culet
The culet is the facet (or point) at the very bottom of a stone. On modern diamonds, the culet is usually cut to a sharp point or an infinitesimally small facet. You’d never see it with the naked eye.
Old mine cuts are different. Their culets are large enough to be visible when you look straight down through the table. You’ll actually see a small facet, almost like a tiny window, at the center of the stone. Some people find this distracting. Others find it charming and authentic. It’s one of the hallmarks of vintage craftsmanship, lending the diamond a distinctive depth and character that modern stones deliberately avoid.
Fire, Brilliance, and Scintillation
Three different types of sparkle, and they’re not interchangeable:
- Brilliance is white light reflecting back to your eye. The “bright” part of sparkle.
- Fire is white light splitting into spectral colors, the rainbow flashes you see when a stone moves.
- Scintillation is the pattern of light and dark areas as you tilt the stone, the twinkling effect.
Old mine cuts emphasize fire over brilliance. Their large facets split light into broad, colorful flashes rather than returning concentrated white light. This is the “candlelight sparkle” that makes antique diamonds feel warm and romantic rather than clinical.
Getting the Look: Material Terms
Moissanite
Silicon carbide, 9.25 on the Mohs hardness scale (diamond is 10). Moissanite produces more fire than diamond because of its higher refractive index (2.65 vs. diamond’s 2.42). In modern brilliant cuts, that extra fire can sometimes read as “too much” and give the stone a disco-ball quality that tips people off.
But in an old mine cut? Moissanite is actually an ideal choice for this aesthetic. The chunky, large-facet pattern of old mine cuts tames moissanite’s fire into broad, warm flashes that look remarkably similar to antique diamond behavior. Old cut moissanite has a romantic, antique look with a softer glow, unlike the sharp brilliance of modern cuts. Practitioners on Reddit’s r/Moissanite community regularly share their Taylor Swift-inspired moissanite rings, and the general consensus is that the old mine faceting pattern is one of the most natural-looking applications for the stone.
For a deeper comparison between the two materials, our moissanite vs. diamond guide breaks down cost, sparkle, and durability side by side.
Lab-Grown Diamond
A diamond with the same chemical, optical, and physical properties as a mined diamond, created in a laboratory. One gemologist quoted in the Globe and Mail predicted that after Swift’s ring, “you’ll probably see a lot of diamond cutters in India cutting lab-grown diamonds in similar designs.” A lab-grown diamond can be valued at up to 90% less than a natural diamond of similar quality, making it a viable path to a larger old mine cut stone.
If you’re weighing lab-grown diamonds against moissanite, our comparison guide covers the practical differences.
Old Mine Cut Moissanite
This is now a real product category, not just a theoretical idea. Specialist cutters produce moissanite stones with genuine old mine cut faceting: 58 facets, high crown, deep pavilion, and a visible culet. The distinguishable features faithfully reproduce the historic brilliant cut pattern. These aren’t just regular cushion moissanites with a marketing label. The faceting geometry is different, and the light performance reflects that.
Multiple vendors on Etsy and specialty jewelry sites now stock them, though one practical note from the Bellwether Events blog is worth heeding: “Be sure you read the descriptions on Etsy carefully before buying a ring. You should be clear on what the setting is made out of, and if the stone is mined or lab-grown.”
The Authenticity Debate
Here’s something almost no competitor article addresses honestly. Not all experts agree that Swift’s stone is actually a true antique old mine cut. Master gemologist Harold Lindsay of Imperial Gem Lab believes that the stone may be a modern diamond cut to take on some of the characteristics of the old mine cut. “I’ve never seen an old mine cut in those dimensions,” he said, noting the extremely rare combination of that carat weight and elongation ratio in a genuine antique stone.
This is practically important for shoppers. If even Swift’s ring might be a modern stone cut in an old mine style, then buying a modern moissanite or lab-grown diamond cut the same way is not a compromise. It’s the same approach, potentially at a tiny fraction of the cost.
Bespoke and Custom Rings
The design process behind Swift’s ring involved Travis Kelce working directly with Kindred Lubeck over an extended period. He selected the stone, collaborated on the setting design, and approved the hand-engraved details. That’s what bespoke means in jewelry: a ring designed from scratch for one specific person.
You don’t need a celebrity budget to go custom. Many jewelers, including smaller online workshops, will work from reference images and specifications to create a one-of-a-kind ring.
The Designer: Kindred Lubeck and Artifex Fine Jewelry
Taylor Swift’s engagement ring was designed by Kindred Lubeck, a New York City-based jewelry designer and founder of Artifex Fine Jewelry. The brand specializes in vintage-inspired, handcrafted pieces with an emphasis on hand engraving.
As Swift described it in an interview: “He designed it with this amazing jeweler, Kindred Lubeck. She does all of her gold engraving by hand.”
Four months after the engagement, Lubeck launched a capsule collection with Sotheby’s, cementing the career-defining impact of this commission. Her brand name, Artifex, comes from the Latin word for craftsman, and her tagline, “borne of rebellion,” reportedly resonated with Swift.
The Trend Impact: By the Numbers
The Taylor Swift engagement ring didn’t just generate headlines. It measurably reshaped what people search for, what jewelers stock, and what brides want.
- Pinterest searches for old mine cut engagement rings rose 800% between January and August 2025

Frequently Asked Questions
What cut is Taylor Swift’s engagement ring?
The ring features an old mine brilliant cut diamond with an elongated cushion shape. Old mine cuts originated in the 1700s and are characterized by 58 hand-cut facets, a high crown, small table, deep pavilion, and visible culet. The stone is estimated at 8-10 carats with an unusually elongated ratio of approximately 1.50+.
How much did Travis Kelce spend on Taylor Swift’s engagement ring?
Estimates vary significantly. A Jared Jewelers VP estimated $250,000 to $500,000 via Yahoo, while Angara placed the range at $500,000 to $1 million. Marie Claire referred to it as a “rumored seven-figure sparkler.” The wide range reflects uncertainty about the stone’s exact carat weight, color grade, and clarity.
Who designed Taylor Swift’s engagement ring?
Kindred Lubeck, founder of Artifex Fine Jewelry in New York City. Lubeck specializes in hand-engraved, vintage-inspired jewelry. Kelce collaborated with her on the design, and Swift herself confirmed the partnership in interviews.
Can I get a ring that looks like Taylor Swift’s for under $500?
Yes. The design language of the ring, specifically the old mine cut faceting, bezel setting, and yellow gold, can be replicated in moissanite at a fraction of the cost. Moissanite’s fire actually works beautifully with old mine cut faceting patterns. For options in this range, our guide to engagement rings under $500 is a practical starting point.
Is Taylor Swift’s diamond really an antique old mine cut?
There’s genuine debate. Master gemologist Harold Lindsay has stated he believes the stone is likely a modern diamond cut to replicate old mine characteristics, given that genuine antique stones of that size and elongation are extraordinarily rare. Whether the stone is truly vintage or a modern homage doesn’t change the aesthetic, and it actually validates using modern moissanite or lab-grown stones cut in the old mine style.
Why did they choose yellow gold instead of platinum?
Yellow gold warms the appearance of an antique-style stone and lets the diamond’s fire read more naturally against the metal. Platinum and white gold tend to emphasize cool, white brilliance, which suits modern cuts but can flatten the warm, romantic glow of an old mine cut. The choice of 18K specifically provides a rich gold color while being soft enough for Lubeck’s hand-engraving technique.
What is the “button back” on Taylor Swift’s ring?
A button back is a small bezel that sits behind the main stone, visible from the underside of the ring. It adds structural support and gives the setting a finished appearance when viewed from any angle. It’s an uncommon detail that you’d typically find on high-end bespoke jewelry rather than mass-produced rings.
Why has the old mine cut become so popular since the engagement?
One ring on one famous finger essentially introduced millions of people to a diamond cut they’d never heard of. The combination of Swift’s massive cultural influence, the ring’s genuinely distinctive appearance, and the vintage aesthetic trend that was already building created a perfect storm. Search data confirms it: old mine cut interest increased 608% over five years, with the sharpest spike in August 2025 when the engagement was announced.
