Timothée Chalamet recently made headlines not only for his relationship with Kylie Jenner but also for his striking fashion choice at a basketball game. The couple was spotted at the Rocket Mortgage FieldHouse in Cleveland on May 25, 2026, as they cheered for the New York Knicks in their match-up against the Cleveland Cavaliers.

On this occasion, the actor turned heads with a remarkable diamond necklace designed by jeweller Alex Moss. Standing out amidst the usual casual sportswear, Chalamet opted to elevate his game-day attire with an eye-catching piece that sparkled in the arena lights. The necklace in question is the St. Mark Necklace, boasting around 3,500 diamonds set meticulously on a combination of 14K rose gold and white gold. Together, these elements create an impressive display weighing nearly 25 carats.


Alex Moss, a New Yorker like Chalamet, shared insights into the creation of this glamorous accessory. The St. Mark Necklace belongs to Moss’s inaugural collection, dubbed the Cathedral of Dreams, and it is described as a “signature link.” According to Moss, such statement pieces can retail anywhere from £20,000 to over £200,000, showcasing the luxurious nature of the item Chalamet chose for his outing.
The connection between the actor and the jeweller was facilitated through Chalamet’s stylist, Taylor McNeill. In a recent interview, Moss recounted how Chalamet visited his SoHo store to browse a selection of jewellery. “It was great because he’s a genuine New Yorker. We had a chat, and I showed him various options. After looking at five or seven different necklaces, he made his choice,” said Moss, expressing enthusiasm about the collaboration.
Chalamet’s discerning choice in accessories did not go unnoticed by Moss, who described the actor’s style as having an effortless coolness. He praised Chalamet’s understanding of fashion, noting his laid-back yet sophisticated vibe. “Timothée was incredibly humble and easygoing; he felt like someone I went to school with in New York,” Moss added, highlighting the actor’s down-to-earth personality.
This recent appearance is not the first time Chalamet’s choice of jewellery has made an impact. Earlier this year, at the 2024 Golden Globes, he donned a vintage Cartier necklace that captivated not only fans but also the attention of Jenner, who could hardly keep her hands off the beautifully crafted piece during the event. This moment added a touch of romance to their public debut as a couple, eliciting warmth from their supporters.
Chalamet’s ability to seamlessly blend casual and luxurious fashion continues to set trends and generate interest among fans and fashion aficionados alike. His proven sense of style, combined with a willingness to experiment with bold accessories, positions him as a transformative figure in the realm of contemporary celebrity fashion.
As the couple continues to gain public attention, it remains clear that both Chalamet and Jenner are influencing style discussions across social media and beyond. Their coordinated fashion choices at events not only capture the spotlight; they also reflect a shared appreciation for aesthetics and self-expression.
The Knight-Cavaliers game not only served as a platform for Chalamet to showcase his fashion sensibility but also highlighted a burgeoning celebrity romance, followed with keen interest by fans around the world. As they step out together more frequently, audiences will undoubtedly be on the lookout for their next fashionable outing and the intriguing accessories that may accompany it.
