Zoe Kravitz stars in Jessica McCormack's Orbit jewelry campaignJessica McCormackZoe Kravitz was seen out and about in London earlier this week, with a huge diamond solitaire on her ring finger, thought to be an engagement ring from Harry Styles. The couple have apparently been dating since August 2025 and have been seen regularly in London, New York and Rome, but this is the first time Kravitz has been snapped with what is thought to be a new ring.Details are scarce, but jewelry experts believe that the diamond could be anything between five and 10 carats, a bezel-set sparkler that chimes perfectly with Kravitz’s minimalist cool-girl style. For Jill Sassone, founder and creative director of San Diego-based Marrow Fine who sent comments by email, “Zoë Kravitz’s engagement ring appears to be a mega elongated cushion-cut diamond, which could be around 7-10 carats, in a yellow gold bezel setting. Everything she wears feels intentional, understated, and effortless and that same ease comes through in this ring (despite the size of the diamond).”Harry Styles and Zoe Kravitz are seen on March 09, 2026 in New York City.

Taylor Swift, Miley Cyrus and Zendaya have all worn similarly-sized diamond solitaire engagement rings over the past 18 months, choosing larger stones in more understated settings that let the diamond radiance shine through.MORE FOR YOUA bezel-and-claw diamond engagement ring by Marrow FineMarrow Fine“Bezel-set diamonds sit right at the tension point between modern and vintage, which is why they feel so relevant right now,” says Aditi Daga, co-founder of jewelry brand Angara. “That duality is incredibly powerful in today’s market, where buyers want something that feels personal and timeless simultaneously.” Angara reports growing interest in bezel settings — a diamond-setting technique in which the stone is set into a metal ‘frame’, rather than being held by claws as in more traditional settings —and is preparing for a spike in demand for bezel-set diamond rings through June, during peak engagement season.Kravitz stars in the most recent campaign for Jessica McCormack, the London-based fine jewelry brand which opened a flagship on Madison Avenue last year. In visuals for the Orbit Collection, she is seen wearing McCormack’s signature Georgian cut-down setting diamond jewelry, alongside the Planetary necklace, designed to mimic the solar system with rare gemstone beads including a 7.92 Columbian emerald, a golden South Sea pearl and a 13.26 star sapphire bead.A cut-down-set diamond necklace from the Orbit collection by Jessica McCormackJessica McCormackKravitz was made the house’s first-ever ambassador in 2025, and while McCormack is known to have designed a previous ring for her brief engagement to Channing Tatum, there has been no confirmation from the house regarding this one. Whoever the designer is, one thing is for certain however: a large diamond in a minimalist setting is ‘golden’ for Styles’ fiancée.
