Our Story
KIL Promotions was founded in January 2023 by CEO Konstantinos I. Leoussis in response to the need for more affordable, supportive jewelry trade shows in the New York City area.
About Us
Who We Are
KIL Promotions develops and produces carefully curated shows that connect respected exhibitors with collectors and enthusiasts of jewelry, antiques, art, and exceptional objects.
Building a World-Class Show
Our signature event, NYC Jewelry, Antique & Object Show, debuted in November 2023 with 40 exhibitors. Since then, it has grown into a premier destination for more than 150 dealers from around the world, showcasing an exceptional selection of antique and vintage jewelry, antique silver, Chinese and Japanese art, vintage designer handbags, sunglasses, and other unique collectibles.
From Coast to Coast
Building on that success, KIL Promotions expanded to the West Coast with the launch of the biannual Hillsborough Show in San Mateo, California (formerly the Hillsborough Antique + Art + Design Show). With plans to expand internationally, as well as into Los Angeles and Houston in 2026 and 2027, we continue to grow our community of exhibitors and buyers.
Introducing Newport JAOS
Introduced in 2025 as an intimate pop-up for vintage jewelry, clothing, and collectible pieces, The Jeweled Collective returns in 2027 as the Newport Jewelry, Antique & Object Show. The expanded show will bring together independent dealers offering vintage and contemporary jewelry, antiques, designer accessories, and distinctive objects.
The KIL Difference
We believe great shows are defined by the quality of the experience, from the venue and audience to the support behind the scenes.
