There was plenty to discuss about Zendaya’s 2025 Golden Globes look: her Joyce Bryant tribute in a burnt orange Louis Vuitton number, her jaw-dropping Bvlgari necklace with a tourmaline pendant, her Old Hollywood waves. But it was a much smaller detail that dominated the conversation: a ring on that finger. Lo, Z appeared to be sporting an engagement ring from her longtime partner Tom Holland. (The couple have yet to officially confirm their engagement.) Eagle-eyed sleuths quickly traced the 5.02 carat cushion cut East-West ring back to jewelry label Jessica McCormack, a growing favorite among the Hollywood It-girl milieu.
In fact, Zendaya wasn’t the only celebrity to adorn herself with Jessica McCormack jewels for the Globes. Zoë Kravitz, the brand’s first-ever ambassador, gussied up her black strapless Saint Laurent dress with a pair of resplendent chandelier earrings made of fourteen pear-cut diamonds (for a total of 26.04 carats), set in blackened white gold.
It’s easy to see why celebrities are drawn to McCormack’s designs: they are simple yet singular. Her blackened bezel setting has become a signature, be it on drop earrings or tennis necklaces. Beyond Kravitz (who also designed a collection for the brand), Billie Eilish, Saoirse Ronan, Dakota Johnson, Margot Robbie, Demi Moore, Victoria Beckham, and Scarlett Johansson are all noted fans of the brand.
The outré Eilish wore a two-strand necklace with a heart-shaped diamond pendant to the 2023 Academy Gala, while Ronan opted for a simple pair of studs for the 2024 British Independent Film Awards. With her broadly pleasing yet telltale designs, Jessica McCormack appeals to all corners of Hollywood—and beyond.
