Timothée Chalamet Wore a Six-Figure Cartier Necklace and a 2,000-Diamond "Good Luck Charm" to the NBA Finals
At Game 1 of the 2026 Finals, the Knicks superfan layered a custom pear-shaped diamond Cartier tennis necklace over a 2,000-stone pavé pendant of his own movie character. The Knicks erased a 14-point deficit to win. The charm, it seems, worked.
Courtside in San Antonio: The Most-Photographed Diamonds in the Building
When the New York Knicks tipped off Game 1 of the 2026 NBA Finals against the San Antonio Spurs at the Frost Bank Center, the broadcast cameras did what they always do — they found the celebrities. And no one in the arena was harder to look away from than Timothée Chalamet, the Knicks' most famous superfan, who turned a courtside seat into a front-row diamond showcase.
Chalamet arrived iced out, layering two genuine showstoppers: a custom Cartier tennis necklace set with pear-shaped diamonds — reportedly a six-figure piece — and, beneath it, a fully diamond-pavé pendant set with more than 2,000 hand-set VVS diamonds. He paired the lot, characteristically, with a vintage-style blue-and-orange Adidas soccer jersey: high jewelry meets streetwear, the exact contrast that sends his looks viral every time.
The Knicks erased a 14-point deficit to beat the Spurs 105–95 and take a 1–0 series lead. The designer behind the pendant had openly called it a "good luck charm" — and after a comeback win like that, the nickname stuck. Here's a full breakdown of the two pieces, and why each one is a genuinely big deal.

The first piece was a custom Cartier tennis necklace set with pear-shaped diamonds. A tennis necklace is the necklace-scale cousin of the classic tennis bracelet: a continuous, uninterrupted line of matched diamonds running all the way around the neck, with no central pendant or focal stone — just diamond after diamond, flowing seamlessly.
What makes Chalamet's version special — and six figures — is the choice of pear-shaped stones rather than the usual round brilliants. Round diamonds are comparatively easy to match and set in a line. Pear shapes are not: each teardrop has a point and a rounded end, so every stone must be matched for size, proportion, and orientation, then set so the line curves smoothly without any stone looking crooked or out of step. It's a far more demanding commission, and the difficulty is exactly why a fancy-shape diamond line like this commands the price it does.

| Maker | Cartier — custom piece |
| Style | Tennis necklace — a continuous, uninterrupted line of diamonds |
| Diamond Shape | Pear-shaped (teardrop) — far harder to match and set than rounds |
| Reported Value | Six figures |

The "Good Luck Charm": A 2,000-Diamond Pendant of His Own Movie Character
The piece that captured the headlines hung beneath the necklace: a custom diamond pavé pendant from The Crown Collection, designed by Ryan Rehbock and commissioned through designer Doni Nahmias, who created the merch line for Chalamet's film Marty Supreme. The pendant is set with more than 2,000 hand-set VVS diamonds — VVS being "very, very slightly included," the second-highest clarity grade, meaning inclusions are nearly impossible to spot even under magnification.
It's not a flat charm. The pendant is a three-dimensional, diamond-encrusted figure depicting Chalamet's character from the film running through the streets of New York, hanging from its own diamond tennis chain — a sculptural piece of wearable cinema. Rehbock has described it as a work meant to "immortalize a moment in time," and revealed he had just ten days to take it from concept to finished, fully-set piece. It was originally created as a gift for Chalamet's 30th birthday in late December, around the film's Christmas-Day premiere — and it has since become his courtside lucky charm.
"I designed this pendant to immortalize a moment in time. This piece was made with an incredible amount of care and passion, and I'm so grateful Timothée connected with it so strongly."

What Chalamet's Courtside Diamonds Tell Us About Jewelry Right Now
A movie star wearing diamonds to a basketball game might sound like simple celebrity noise — but Chalamet's two pieces are a near-perfect snapshot of where fine jewelry is in 2026.
Custom Is King
Both pieces were custom — the pear-shaped Cartier necklace and the bespoke pendant. The biggest moments in jewelry today aren't off-the-shelf; they're commissioned, personal, and one-of-a-kind. That's exactly the kind of work an independent fine jeweler lives for.
Jewelry With a Story
The pendant wasn't just diamonds — it was a 3D portrait of a character, a birthday gift, and a "good luck charm" all at once. Pieces that carry meaning and narrative are what people connect with. The story is now as valuable as the stones.
Men's Jewelry Is Booming
Courtside has become the new red carpet for men's jewelry. Diamond necklaces, pendants, and tennis chains on male celebrities are driving a major surge in demand for men's fine jewelry — a category that's grown dramatically in just a few years.
Fancy Shapes Are Having a Moment
Chalamet's necklace used pear-shaped diamonds, not rounds — part of a broader move toward fancy shapes (pear, marquise, oval, elongated cushion) across both engagement rings and statement pieces. Distinctive cuts are the new way to stand out.

Common Questions About Chalamet's NBA Finals Jewelry
What jewelry did Timothée Chalamet wear at the NBA Finals?
At Game 1 of the 2026 NBA Finals between the Knicks and Spurs, Chalamet wore two custom diamond pieces: a Cartier tennis necklace set with pear-shaped diamonds, reported to be a six-figure piece, and beneath it a diamond pavé pendant from The Crown Collection set with more than 2,000 hand-set VVS diamonds. He styled both over a vintage-style blue-and-orange Adidas soccer jersey.
What is the "good luck charm" pendant?
It's a custom diamond pavé pendant created by The Crown Collection, designed by Ryan Rehbock and commissioned through designer Doni Nahmias. Themed around Chalamet's film Marty Supreme, it's a three-dimensional, diamond-encrusted figure of his character running through the streets of New York, set with more than 2,000 hand-set VVS diamonds and hanging from its own diamond chain. Rehbock called it a "good luck charm," and after the Knicks erased a 14-point deficit to win Game 1 105–95, fans embraced the nickname.
How much is Chalamet's Cartier necklace worth?
The custom Cartier tennis necklace is reported to be a six-figure piece. A large part of that value comes from the use of pear-shaped diamonds rather than round ones — fancy-shaped stones are significantly harder to match and set in a continuous line, which raises both the craftsmanship required and the price. Exact figures haven't been publicly confirmed by Cartier or Chalamet's team.
What does VVS mean, and why does it matter for the pendant?
VVS stands for "very, very slightly included" — the second-highest clarity grade on the diamond clarity scale, just below flawless and internally flawless. It means any internal inclusions are so tiny they're extremely difficult to see even under 10x magnification. Using more than 2,000 VVS diamonds across a single pendant means a remarkably clean, bright, consistent sparkle throughout the entire piece — and a much higher material cost than lower clarity grades would carry.
What is a tennis necklace, and why are pear-shaped diamonds special?
A tennis necklace is a continuous, uninterrupted line of matched diamonds set all the way around the neck — the necklace-scale version of the classic tennis bracelet, with no central pendant. Building one from pear-shaped (teardrop) diamonds, as Chalamet's was, is significantly more difficult and costly than using standard rounds, because each fancy-shaped stone must be matched for size, proportion, and orientation, then set so the line curves smoothly without any stone looking out of place. That craftsmanship is a big part of why such a piece reaches six figures.
