The NYC Jewelry, Antique & Object Show (NYCJAOS) is expanding to more than 160 exhibiting dealers for its autumn 2025 edition, quadruple the number at its inaugural show just two years ago.
NYCJAOS returns to Metropolitan Pavilion, located at 125 W. 18th St. in Manhattan’s Chelsea neighborhood, from Nov. 21 to 23. The show kicks off with a special VIP ticketed preview from 11 a.m. to 1 p.m. on Friday, Nov. 21.
Konstantinos “Kon” Leoussis, founder of KIL Promotions, which organizes NYCJAOS, says he is proud that the show has grown to serve the demand for luxury thrifting and vintage goods among luxury shoppers in the New York metro area.
“I’m really excited to celebrate the second anniversary of NYCJAOS this November,” says Leoussis, also the founder of vintage jeweler KIL N.Y.C. “Two years ago, we started with 40 dealers and a handful of booths. Our show has now grown into more than 160 dealers, and we are on track to sell out of all of our booths. It really shows that what we’ve created has resonated with so many dealers from across the world.”
Konstantinos Leoussis brings pieces such as this antique sepia mourning locket, which he recently sold, to NYCJAOS for collectors to browse or purchase.
At NYCJAOS, consumers have the chance to browse and purchase everything from antique handbags to scarves to watches to fine silver goods. The show specializes in art objects and rare collectibles, as well as both new and old jewelry. Leoussis says it’s the ultimate destination for those seeking authenticity and value, as visitors can learn about the provenance and story behind each piece.
With offices in Brooklyn and Manhattan, Leoussis established KIL Promotions in 2023 as an antidote to the lack of diverse direct-to-consumer jewelry-related events in New York City. His company is dedicated to creating accessible opportunities for vendors from all over the world and curating a range of shows featuring antique and vintage jewelry and watches, art objects, and contemporary jewelry design.
Earlier this year, KIL Promotions acquired the Hillsborough Antique Show in San Mateo, Calif. Leoussis says he is working with previous and new exhibitors for that show and hopes to revitalize it from top to bottom in its next iteration.
“Being a jeweler myself, I know the power of fine jewelry and its unique ability to help people express something about themselves,” Leoussis says. “Vintage jewelry and objects hold genuine meaning and enduring value, each with its own place in history, giving you so much more than typical luxury goods—you also get the story that comes with it.”
