Vintage jewelry pop-up and sports jewels shine in New York

At Alessandro Berni Gallery, 511 W. 25th St. in Chelsea, about 20 exhibitors are gathering June 25-28 for The Jeweled Collective, a four-day sale where a buyer can move from antique and vintage jewels to contemporary fine jewelry and luxury watches in one room. The smartest finds are the ones with visible clues: hallmarks, repaired clasps, replaced stones, crisp enamel, and original boxes or paperwork that help separate a true period piece from a later rebuild.

KIL Promotions, founded in January 2023 by CEO Konstantinos I. Leoussis, says the pop-up is meant to offer a more humanistic, supportive alternative to the usual convention circuit. The company launched NYCJAOS in November 2023 with 40 dealers and says that show has grown to more than 150 dealers from around the world, a scale that matters when provenance questions get specific and a seller can explain where a jewel came from, what has been altered, and what still needs to be checked.

The exhibitor list already signals range: Amazing Jewelry, KIL NYC, Halle’s Jewels, Alpha Omega Jewelry, Forever Jewelry, Greenwich Bazaar, Rosaria Varra, and Sean Randall are among the names on the floor. That mix makes this a practical stop for a collector looking for signed pieces, estate jewelry, and watch inventory, not just display-case sparkle. Ask where a ring’s shank has been resized, whether a clasp is original, if a necklace has been shortened, and whether any stones are later replacements. Those are the details that change both value and wearability.

Just uptown, the American Museum of Natural History is offering a different kind of education with For the Win: Objects of Sports Excellence, which opened May 15 in the museum’s permanent exhibition areas and is included with admission. The show spans more than 70 objects from more than 15 sports and nearly 150 years of history, including championship rings, Olympic medals, trophies, belts, and jewelry. Among the highlights are Jesse Owens’s 1936 Olympic gold medal, the Vince Lombardi Trophy, Breanna Stewart’s 2024 New York Liberty championship ring, Kevin Durant’s 2024 Team USA gold medal, Yogi Berra’s Babe Ruth Crown, Claressa Shields’s T-Rex championship belt, and Chris Evert’s tennis bracelet.

Placed inside the Mignone Halls of Gems and Minerals, which reopened in 2021 with more than 5,000 specimens from about 95 to 98 countries, the exhibition turns sports prizes into objects to read closely. For collectors heading to The Jeweled Collective, that museum context is useful: a jewel becomes more legible when you look at how a medal, ring, or bracelet carries history in the metal, the stones, and the wear.
