Timothée Chalamet has big dreams for the Knicks.
The 30-year-old actor visited San Antonio’s Frostbank Center to cheer on his beloved New York Knicks, who will face the Spurs in the 2026 NBA Finals, and he also brought along a good luck charm.
The accessory in question: a custom diamond pavé “Marty Supreme” pendant from the Crown Collection. It was designed by Ryan Rehbock and commissioned through designer Doni Nahmias, who created the merchandise collection that was heavily promoted in the film.
“I designed this pendant to immortalize the iconic image[of Marty]running through the streets of New York with a briefcase,” Lehbock told Page Six Style of the piece, which depicts Chalamet’s character running through the city. This scene also appears on the movie poster.
The pendant is encrusted with more than 2,000 hand-set VVS diamonds, “with meticulous bright cut lines to bring out every detail,” Rehbock said.
Chalamet paired the pendant with a blue and orange Adidas soccer jersey and a Cartier tennis necklace set with pear-shaped diamonds. This is a custom piece worth six figures. His girlfriend Kylie Jenner, 28, is also an avid fan of pear-cut stones. She wore two Lorraine Schwartz pear-shaped diamond studs (both in one ear) and two pear-cut pinky rings from the jewelry store to several Knicks playoff games.
The connection between Reebok and Chalamet began at the Nahmias studio where the Crown Collection jeweler worked. When Nahmias asked him to make a keychain for the actor, it was a pavé diamond ping pong paddle and a silver Running Man hanging from a carabiner.
Chalamet loved the keychain so much that he clipped it to the belt loop of his jeans when he appeared on The Tonight Show Starring Jimmy Fallon in December.
As for the pendant itself, Rehbok took it from concept to completion in just 10 days. It was a birthday present for the actor, who turned 30 on December 27, just on the day of the movie’s Christmas premiere.
“This work was created with incredible care and passion, and we are very grateful to Timothy for his strong involvement in this work,” said Lehbock. “Having the pendant become part of a memorable moment made this project even more meaningful.”
Lehbock, who has also designed pieces for Post Malone and Billie Eilish, called the pendant a “lucky charm” in an Instagram post Wednesday.
The pendant is just the latest in a rotating lineup of statement necklaces that Chalamet has brought courtside this postseason. During the Knicks’ playoff run, he wore two Cartier Panthere diamond pendants (worth approximately $14,000 and $30,000, respectively), a 47-carat Alex Moss St. Mark chain in white gold, and a Prada diamond chain.
That brilliance seemed to pay off, as the Knicks erased a 14-point deficit to defeat the Spurs 105-95 and take a 1-0 lead in the series. Game 2 is Friday in San Antonio, and Chalamet is sure to shine on the sideline.
