Zoë Kravitz’s engagement ring is so blinding, you might need to blink twice.

The 37-year-old wore her enormous sparkler from Harry Styles while out and about in NYC Monday, days after Page Six exclusively reported the celebrity couple were engaged.

Ajay Anand, CEO of Rare Carat, tells Page Six Style the center stone could be anywhere from 10 to 12 carats in size — and worth as much as $800,000.

The “seriously huge” elongated cushion-cut diamond looks to be set in a yellow gold bezel, per Anand, giving it an “effortlessly chic, almost understated feel despite the sheer size of the stone.”

Lorel Diamonds‘ Laura Taylor agrees with the cut of Kravitz’s ring, telling us it could be worth up to $600,000.

“The bezel setting frames the diamond in yellow gold rather than using traditional claws, which gives the ring a cleaner and more modern feel. It also makes the stone feel more integrated into the overall design, rather than simply sitting on top of the band,” Taylor said.

While the couple have yet to confirm the designer behind the gorgeous bauble, Taylor notes, “Given Zoë’s existing relationship with Jessica McCormack, it would not be surprising if this were another custom design from the brand.”

As McCormack’s first brand ambassador, Kravitz often wears the jeweler’s pieces on the red carpet — and even modeled a similar ring in a November 2025 photo shoot.

Reps for Jessica McCormack did not immediately answer Page Six Style’s request for comment.

McCormack does not list prices online for her larger engagement rings similar to Kravitz’s, but a 2.98-carat emerald-cut sparkler featuring her signature button backing retails for $100,000.

Kravitz was previously engaged to Channing Tatum, who proposed with a McCormack-designed elongated cushion-cut diamond ring estimated to be worth $500,000. The pair never made it down the aisle, calling it off in 2024 after three years.

She was also married to Karl Glusman; her 2018 engagement to the “Nocturnal Animals” actor went largely unnoticed for months until she casually confirmed the news in an interview with Rolling Stone.

While Kravitz and Glusman divorced in 2021, her taste in rings hasn’t changed much over the years; all three have been vintage-inspired. Purchased from antique jeweler The One I Love NYC, the star’s circa-1800 Georgian half-loop sparkler from Glusman was set with over 2.5 carats of rose-cut diamonds.

Styles (who has never been engaged nor married) and Kravitz have been together for less than a year, but sources tell Page Six he “would jump off a cliff for her” and the bride-to-be is on “cloud nine.”
