Zoë Kravitz debuts 9-carat engagement ring from Harry Styles at London jewellery event

Zoë Kravitz has publicly showcased her engagement ring from fiancé Harry Styles for the first time, appearing with the diamond piece at a jewellery event in London.

The actress attended a Jessica McCormack event on June 24 wearing a white one-shoulder dress, paired with satin heels, a diamond arm cuff, a chunky bangle and oversized sunglasses.

The appearance drew attention to the large diamond ring on her left hand, marking the first public sighting of the engagement jewellery since reports of the couple's engagement emerged earlier this year.

Kravitz, 37, and Styles, 32, were first linked romantically in August 2025. In April 2026, a source told People that the singer had proposed after eight months of dating.

According to the source, the couple had already shared the news with a small group of close friends and family.

Jewellery experts cited in reports have estimated that the ring features a cushion-cut diamond set in yellow gold.

Olivia Landau of The Clear Cut told InStyle that the stone appears to be between six and nine carats, with several observers estimating it to be closer to nine carats.

Landau estimated the value of the ring at approximately $500,000. Other reports have suggested the piece could be worth as much as $1 million, depending on factors such as the stone's cut, clarity and whether the design is custom-made.

Lisa Ingram, vice president of KAY Jewelers, offered further observations about the design in comments reported by People.

“From what we can see, the stone sits low in the basket for a sleek, modern profile,” Ingram said. “It is adorned with what appears to be a thin gold bezel. It's finished on a thin, minimalist yellow gold band.”

The appearance has also prompted speculation among some fans about the ring's origins.

Kravitz serves as Jessica McCormack's first brand ambassador, collaborator and muse, leading some observers to suggest the piece may have been created by the luxury jeweller.

Neither Kravitz nor Styles has publicly commented on the ring's design or value.
