Josh Hart and Karl-Anthony Towns turn heads with Knicks diamond necklaces: The story behind the 12.3-carat piece of jewelry marking history.

The New York Knicks’ historic championship victory created countless memorable moments, but one of the most talked-about details from the celebration came in the form of a piece of jewelry. As the team ended a more than five-decade championship drought and captured their first NBA title since 1973, the city of New York was covered in blue and orange — and the celebration came with a serious amount of diamond sparkle.

Behind the dazzling necklaces worn by Knicks stars Josh Hart and Karl-Anthony Towns was celebrity jeweler Alex Moss, a longtime Knicks fan who created a custom diamond pendant designed to commemorate the team’s championship journey. The piece was not originally made as a commercial product but as a personal art creation meant to capture what Moss believed could become a historic sports moment.

“I knew they were going to win. I f—king knew they were going to win this thing. So I made it,” Moss said while describing the inspiration behind the design. The pendant features 12.3 carats of VVS white diamonds set in yellow gold, crafted in the shape of the NBA Championship Trophy, turning the celebration into a wearable symbol of victory.

Moss created the necklace before Game 1 of the NBA Finals, trusting his belief that the Knicks had what it took to complete their championship run. After the team defeated the San Antonio Spurs and secured the title, he shared the design on Instagram, and the reaction from the Knicks world was immediate.

Josh Hart became the first player to reach out about the piece. The morning after the championship was secured, Hart contacted Moss at around 7 a.m., seemingly still caught up in the excitement of the historic win. The guard quickly arranged to purchase the necklace and became one of the first Knicks players to publicly wear the exclusive design.

Hart proudly wore the diamond pendant during the team’s appearance on “The Tonight Show Starring Jimmy Fallon” just days after the unforgettable Game 5 victory. He later kept the same piece on while throwing the ceremonial first pitch at the Yankees vs. White Sox game alongside Knicks teammate Jalen Brunson, turning the necklace into one of the most recognizable symbols of the championship celebration.

Karl-Anthony Towns soon followed, reaching out to Moss to secure matching necklaces for himself and his fiancée Jordyn Woods. The couple appeared together at the Knicks victory parade wearing the same glittering design, creating a coordinated fashion moment that quickly caught attention among fans and media.

Towns arrived at the parade wearing a leather jacket, backward cap and reflective sunglasses, pairing the relaxed style with the luxury championship pendant. For Woods, the matching necklace became another example of how fashion and sports culture have become increasingly connected, especially during major moments like an NBA championship celebration.

The jewelry was created at Moss’ New York-based factory and atelier, where his team worked quickly to complete the custom orders in time for the players’ public appearances. The ability to produce such a detailed piece on a tight schedule reflected both the craftsmanship and the reputation Moss has built within the luxury jewelry world.

Originally born in Toronto, Alex Moss has spent more than 12 years building his career in New York City. Since the beginning of his journey, he has designed and produced his jewelry in the city, developing a brand identity closely connected to the energy and creativity of New York.

“I think that it’s important to embrace people from this city who are doing great things for the city,” Moss explained. “We live and breathe New York, everyone in the company. Imagine if someone like Jason of Beverly Hills was making the Knicks pieces. It just doesn’t make sense.”

For Moss, creating the Knicks championship jewelry was not only about luxury but also about representing the connection between local talent and the city’s biggest cultural moments. As a Knicks fan who attended the team’s dramatic Game 4 victory at Madison Square Garden, he viewed the project as a personal celebration of New York’s long-awaited basketball success.

The jeweler has become known for designs that combine traditional luxury with a more rebellious and modern attitude. Moss describes his style as “very anti-establishment” and “very f—k you,” even referring to himself as “the Ferrari of jewelry.” His approach has attracted a wide range of celebrity clients who appreciate his bold and unconventional creations.

Among the famous names who have worn Moss’ designs are Drake, Takashi Murakami, Hailey Bieber, North West and Timothée Chalamet. Knicks superfan Chalamet previously wore Moss jewelry while supporting the team during the playoffs, including a nearly 25-carat diamond Saint Mark necklace while sitting courtside.

The relationship between Moss and celebrity culture reflects the growing role of jewelry as a form of personal storytelling. For athletes and entertainers, custom pieces often represent achievements, identity and major milestones rather than simply serving as accessories.

Josh Hart’s connection to the Knicks championship moment also reflects his growing importance within the team’s culture. Known for his energy, competitiveness and personality both on and off the court, Hart quickly became a fan favorite after joining New York. His emotional connection with the city made the championship celebration even more meaningful for supporters.

Karl-Anthony Towns also experienced a major career milestone with the Knicks’ historic victory. After years of success in the NBA, joining New York placed him at the center of one of the league’s most passionate fan bases. His championship celebration with Jordyn Woods showed the personal side of a player experiencing one of the biggest moments of his career.

Outside of basketball, Towns’ relationship with Woods has also attracted public attention. The couple has often shared glimpses of their life together, balancing high-profile careers while maintaining a strong presence in entertainment and fashion circles. Their matching championship necklaces became a visual representation of celebrating both personal and professional success.

For Alex Moss, the Knicks championship necklace may become one of the defining creations of his career. The piece captured a rare moment when sports, celebrity culture, fashion and New York identity came together. It was not simply a diamond accessory but a symbol attached to a historic achievement that fans had waited decades to witness.

When asked whether he could eventually design the official championship rings for the Knicks, Moss left the possibility open. His answer reflected the confidence that has become part of his brand: “It’ll look like nothing anyone’s ever seen before.”

As New York continues celebrating the Knicks’ unforgettable championship season, the diamond pendants worn by Josh Hart, Karl-Anthony Towns and Jordyn Woods remain one of the most distinctive details from the victory celebrations. Created from passion, belief and a deep connection to the city, the jewelry became a reminder that some championship moments are remembered not only by the trophies raised, but also by the stories and symbols created along the way.
