Zoë Kravitz may be saving her words when it comes to her engagement to Harry Styles, but that massive gem on her finger speaks for itself. On Wednesday, the actor and director hosted a Summer Solstice Party alongside friend and jewelry designer Jessica McCormack in London.

To beat the heatwave, Kravitz slipped on a breezy off-white midi dress. The silky piece had an off-the-shoulder neckline and a slouchy fit. It went perfectly with her silver satin slingbacks, big black sunglasses, and layers of silver and diamond jewelry.

Dangly diamond earrings shone on her ears, some cuff bracelets with clear diamonds adorned her arm, and while her right hand debuted a chunky silver ring, her left showed off her massive diamond engagement ring from her fiancé.

The piece is a stunning elongated cushion-cut solitaire diamond set on a skinny yellow-gold band. It is estimated to be 8 to 10 carats. (While we do not know if the design is by McCormack, Kravitz’s engagement ring from ex Channing Tatum did hail from the British jewelry house.)

The Blink Twice director was first spotted wearing the ring while out in London in early April, and a week later, sources confirmed to People that the two had, in fact, gotten engaged.

Kravitz and Styles have been linked since August 2025, when they were first seen out together in Rome, Italy. Since then, they’ve been inseparable—and their couple style has been so in sync. Kravitz has even reportedly called the English pop star her “soulmate.”
