An Insider Look at Zoe Kravitz’s Engagement Ring

An Insider Look at Zoe Kravitz’s Engagement Ring

Designed by London-based jeweler Jessica McCormack, Zoe Kravitz’s engagement ring from Channing Tatum features an elongated cushion-cut diamond of about 7 carats set low in a mix of 18k yellow and blackened white gold. 

The ring was first photographed at the end of October 2023, when Kravitz dressed as Rosemary Woodhouse from the 1968 horror film “Rosemary’s Baby” and Tatum as a giant baby for Kendall Jenner’s Halloween party. The image of that costume night is how most people first met the ring, and it set the tone for everything that has been written about it since.

Cut, Setting, and Reported Size

The center stone is an elongated cushion-cut diamond, set in a low bezel-style mount made from a mix of 18k yellow gold and blackened white gold. That pairing of warm and cool metals is part of what gives the ring its slightly gothic, slightly Georgian look, and it is a hallmark of Jessica McCormack’s house style.

Reported carat weights vary, which is normal for a ring seen only in photographs. Hello Magazine cited a figure of around 7 carats, with one source specifically listing 7.01 carats. Other gemologists estimate the diamond at 8 to 10 carats. The range comes from the angle of each shot, the proportions of the cushion shape, and the portion of the stone hidden by the bezel. Either way, the diamond is a generous solitaire that fills the finger without overwhelming it.

Estimated value reports also vary. Most outlets place the ring between $300,000 and $550,000, with one appraisal pushing closer to $1 million, depending on assumptions about the diamond’s color and clarity. McCormack does not publicly comment on individual private commissions, so these numbers are press estimates rather than official figures.

Most interesting is how quietly the setting sits. The bezel rim hugs the stone without rising above it, so the diamond looks like part of the band instead of perched on top. The result is a ring Kravitz can wear daily, without the high-profile silhouette you might expect from a stone this size.

The metal mix also reveals the ring’s design. Yellow gold gives the band warmth against the skin, while the blackened white gold around the stone appears charcoal-like in close-up photos. That pairing is intentional in McCormack’s work, where the darker frame makes the diamond’s white face appear brighter by contrast. It is a Georgian-era idea with a refreshed look, quieter than a polished platinum solitaire.

The mix of yellow gold and blackened white gold is distinctly McCormack, with the darker frame making the diamond's white face appear brighter by contrast in a technique borrowed directly from Georgian jewelry tradition.

Why the Ring Debuted at a Halloween Party

Kravitz wore the ring in public for the first time at Kendall Jenner’s 2023 Halloween party in late October, the same weekend the engagement occurred. According to coverage at the time, the proposal happened on October 30, 2023.

The Halloween setting suited the ring better than a typical red-carpet appearance. Kravitz went as Rosemary Woodhouse, the lead in Roman Polanski’s “Rosemary’s Baby,” while Tatum joined the bit as a giant baby. The ring sat on her left hand in the photos from the night, and viewers noticed it almost immediately.

There is a soft logic to introducing this ring during a costume party in vintage Manhattan. McCormack’s signature style leans Georgian, with closed-back settings and a quiet, candlelit sparkle. The blackened white gold in the ring gives it a moodier finish than a polished platinum solitaire. Set against the costume and a New York Halloween crowd, the ring came across as a personal piece rather than a press announcement.

The timing also meant the ring had a few days to announce its own, as neither Kravitz nor Tatum gave a formal comment that night. The image traveled, fans zoomed in on the left hand, and outlets like Hello Magazine, Grazia, and Hola.com confirmed the engagement shortly afterward. By the time anyone close to the couple spoke on the record, most readers had already seen the ring and had an opinion about the cut.

The ring's first public appearance, on Kravitz's hand during a costume party, suited McCormack's Georgian-leaning aesthetic better than any red-carpet reveal could have.

Who Jessica McCormack Is and How She Works

Jessica McCormack is a London-based fine jewelry designer who runs her atelier from a five-story 19th-century townhouse at Carlos Place in Mayfair. She was born in Hamilton, New Zealand, in 1989, grew up in Christchurch, and moved to London in 2005 for an internship at Sotheby’s jewelry department. During her time at Sotheby’s, she became drawn to antique jewelry and the hand techniques behind it.

She launched her own brand in 2008 with a debut collection called “Messenger of the Gods.” Rihanna was among the first public figures to wear it. Over the following decade, McCormack built a quiet but loyal client base of collectors who preferred her approach to hand-cut antique stones, low, closed-back settings, and warm gold. Her workshop sits in the basement of the Carlos Place townhouse, where six artisans work on commissions and one-of-a-kind pieces.

McCormack’s signature setting is the button-back, also known as the Georgian cut-down. It is a low, closed-back mount where a thin layer of blackened metal frames each stone and presses the diamond close to the finger. The technique dates to the early 18th- to mid-19th-century, when stones were set in metal-backed cups rather than on open-claw prongs. The finish softens the diamond’s edges in good light and keeps the ring comfortable for daily wear.

Kravitz and McCormack have a long working relationship that predates the ring. In May 2024, McCormack named Kravitz as her brand’s first-ever ambassador. The campaign featured pieces like the Gypset diamond earrings and the Ball n Chain necklace as the brand prepared for its first U.S. store, which opened in New York in 2025. Kravitz spoke about her admiration for McCormack’s work and their collaboration over the years.

That long lead-in matters when you look at the engagement ring. Kravitz already had access to the studio, the workshop, and the designer’s full archive of antique stones. Coverage of the proposal noted that the ring likely involved her direct input into the cut, the metal mix, and the bezel proportions. 

McCormack’s process is more collaborative than off-the-shelf, with the client examining stones in the Carlos Place rooms before any setting work begins. While Tatum handled the proposal, Kravitz created the design.

The Case for an Antique-Leaning Cut

The ring’s softer outline and warmer sparkle borrow from the old mine cut, an antique diamond style that predates modern round brilliants by about two centuries. The stone is described as an elongated cushion cut, although the proportions and design resemble an old mine territory rather than a modern cushion cut.

Developed in the early 1700s, old mine cuts remained fashionable through the late 1800s during the Georgian and Victorian eras. The name refers to diamonds from the older mines of India and Brazil, as well as from later finds in South Africa. According to GIA, old mine cuts have 58 facets, the same as a modern round brilliant, but the proportions differ. The cut features a smaller table, taller crown, deeper pavilion, a thin and often bruted girdle, and a large open culet at the bottom of the stone, rather than a single point. The open cut helps old mine cuts catch light.

Elongated old mine cuts take the traditional squarish cushion outline and stretch it into a longer rectangle. The result is a stone that wears longer on the finger and reads quieter face-up than a square cushion of similar carat weight. Several jewelers, including Goodstone Inc., have brought the elongated old mine cut into their bespoke offerings as part of a wider return to antique-style stones in fine jewelry.

Interest in old mine and old European cuts has returned because cutters turned them for candlelight rather than spotlight. Their chunky facets cast broad flashes of fire in warm, low light, while modern brilliants are cut for sharp white sparkle under brighter, cooler conditions. In everyday settings such as restaurants and at home, antique-leaning cuts appear warmer and more lived-in. Publications such as Marie Claire Australia and The Zoe Report highlighted Kravitz’s ring as part of a broader trend toward antique cuts in recent celebrity engagements.

An old mine or elongated old mine reveals more of itself as the wearer turns the hand, while modern cuts produce a steadier, more uniform return of light. In contrast, antique cuts produce flashes that move and pause, almost like watching a candle flame on a clean glass surface. That quality is hard to capture in a photo, which is why the ring’s coverage featured the words “softer,” “warmer,” and “candlelight” over carat data.

The ring's softer outline and warmer sparkle borrow from the old mine cut tradition, with chunky facets that produce broad, fire-forward flashes in warm, low light rather than the sharp white scintillation of a modern brilliant.

The Engagement, the Breakup, and the Ring Today

Kravitz and Tatum got engaged on October 30, 2023, and the pair had been dating since 2021. They made their first formal red-carpet appearance as a couple at the “Blink Twice” premiere in August 2024, the directorial debut feature Kravitz had spent two years making. About two months later, on October 29, 2024, sources confirmed the engagement was off. Kravitz reportedly returned to Tatum after the split.

Reports cited that the two had grown apart and disagreed about living arrangements. Kravitz lived in New York, where she had lived for years, while Tatum stayed closer to Los Angeles. Neither party gave a public statement at the time. 

As of late April 2026, Kravitz got engaged again, this time to Harry Styles. Her new ring, also likely linked to Jessica McCormack, has an elongated cushion-cut diamond in a yellow gold bezel, with carat estimates from gemologists ranging from about 6 to 10 carats. Coverage from Marie Claire, The Zoe Report, and People framed the new ring as a lighter, brighter version of the same general silhouette Kravitz already favored.

The Tatum ring remains as a chapter rather than a closed loop. It introduced a wider audience to McCormack’s design language and the elongated cushion outline, and it set the stage for the broader visual vocabulary Kravitz carried into her current jewelry choices.

By late April 2026, Kravitz was engaged again with a new ring also likely linked to McCormack, continuing the same elongated cushion silhouette and yellow gold bezel aesthetic she had already made her own.

What the Ring Says About Her Style

The ring aligns with the rest of Kravitz’s jewelry, which leans toward low-profile settings, antique-style cuts, and warm gold over bright white metal. She has been photographed in McCormack’s pieces for years, often layered with smaller stacked rings or thin gold bands rather than a single high-shine statement.

Kravitz’s May 2024 McCormack ambassador campaign leaned into this side of her taste. The Gypset diamond earrings sit close to the lobe and read as everyday pieces, while the Ball n Chain necklace has a quiet, repeating rhythm that is more like a personal heirloom than a logo piece. McCormack calls these “day diamonds,” meant for daily wear rather than special occasions. Before the campaign began, Kravitz mentioned her long working relationship with the designer and her respect for McCormack’s craft.

Kravitz chooses pieces that look hand-finished, sit close to the skin, and pair easily with the rest of her wardrobe. Her stylists and jewelry curator mentioned this in interviews about the antique-leaning trend. The Tatum-era engagement ring fit that pattern, as does the version she currently wears. The cut, setting, and metal combination are an extension of how she dresses, scaled up to attract attention.

If you’re looking for inspiration for your own engagement ring, the lesson is less about carat weight and more about consistency. Kravitz did not choose a ring that clashed with her aesthetic. She picked one that enhanced it, in a soft Georgian framework, by a designer she already loved. Regardless of which proposal it accompanies, the ring feels like hers.

The same principles apply to pieces at more accessible price points. A bezel-style mount keeps the diamond close to the finger and protects the girdle from knocks, which matters for a ring worn during cooking, typing, and travel.

A warm gold band reads softer against most skin tones than a bright white metal, while antique-style cuts appear larger face-up than their carat weight suggests because the proportions favor a wider face over a deeper pavilion. These designs predate Kraviz’s ring, which brought a long-standing conversation into the open with a widely shared photo.

The engagement ring is a natural extension of how Kravitz dresses and the jewelry she's consistently worn, low-profile settings, antique-style cuts, warm gold, and pieces that look hand-finished and sit close to the skin.
