Timothée Chalamet has officially entered his superfan era. The Oscar-nominated actor was once again courtside as the New York Knicks opened their NBA Finals campaign against the San Antonio Spurs. But while fans were focused on the game, Chalamet arrived with something else making headlines: a custom diamond pendant that has quickly become his personal good luck charm. The one-of-a-kind “Marty Supreme” piece, inspired by his upcoming film character, is covered in more than 2,000 VVS diamonds and depicts Chalamet sprinting through the streets of New York. The pendant was designed by jeweler Ryan Rehbock of The Crown Collection and reportedly completed in just ten days as a birthday gift for the actor.
The timing could not have been better.
The Knicks erased a double-digit deficit to defeat the Spurs 105-95 in Game 1, immediately turning Chalamet’s latest courtside accessory into an internet talking point. Sports fans are famously superstitious, but celebrity superstition might be reaching a new level. From lucky jerseys to ritual seating arrangements, athletes and fans alike have long believed certain objects carry winning energy. Chalamet’s diamond-covered talisman appears to have joined that list.
What makes the story particularly interesting is how naturally Chalamet has become part of the Knicks’ identity during this playoff run. Unlike celebrities who appear only when a team starts winning, the actor has spent years publicly supporting New York basketball. His courtside appearances have become so frequent that social media users now joke he deserves a spot in the team’s rotation.
The pendant also continues a larger trend in celebrity fashion, where jewelry is becoming increasingly personal rather than purely luxurious. Instead of wearing generic diamond pieces, stars are opting for custom creations tied to movies, career milestones and personal passions. The result feels less like a status symbol and more like wearable storytelling.
Of course, Chalamet’s collection is hardly subtle. Throughout the Knicks’ postseason journey, he has rotated between Cartier Panthère pendants, a massive Alex Moss chain, Prada diamonds and now the “Marty Supreme” piece. At this point, his jewelry lineup is beginning to rival the team’s bench depth.
Whether the pendant actually brings luck is impossible to prove. What is certain is that the actor has become one of the NBA Finals’ most entertaining sideline attractions.
With New York now holding a 1-0 lead in the series, don’t be surprised if the pendant makes another appearance in Game 2. After all, when a superstition starts working, nobody wants to test fate.
