On a spring evening in New York, Tiffany & Co. transformed the Park Avenue Armory into something between a garden and a reverie. The occasion was the launch of Blue Book 2026: Hidden Garden—the house’s most celebrated annual high jewelry collection, and one of the most anticipated events on the luxury calendar.
The collection, designed by Nathalie Verdeille, Senior Vice President and Chief Artistic Officer at Tiffany & Co., alongside the Tiffany Design Studio, is an ode to the quiet, almost imperceptible transformations of the natural world. Inspired by the legacy of legendary Tiffany designer Jean Schlumberger—celebrated for his ability to translate flora and fauna into sculptural, gemstone-encrusted silhouettes—Hidden Garden is jewelry as storytelling. Bird brooches set with vivid rubies and sapphires nest among tulips. Opal pendants glow like something pulled from the earth rather than made by hand. Diamond necklaces cascade across the décolleté like water. Each piece is extraordinary on its own; together, they form a world.

Presented on models dressed in Givenchy by Sarah Burton—the pairing as considered as the jewels themselves—the collection found its backdrop in a venue steeped in Tiffany history. In 1881, Louis Comfort Tiffany was commissioned to design the Armory’s Silver Room and Historic Veterans Room, two of the last fully intact interiors by the artist. To celebrate the Blue Book here was to celebrate the house’s own legacy, embedded in the walls of one of Manhattan’s most storied spaces.
New York’s most-talked about evening drew a guest list to match. Rosé arrived in a white gown with a lace bodice, photographed alongside Teyana Taylor and Rosie Huntington-Whiteley. Connor Storrie wore a ruby and diamond bird brooch at his lapel—a nod to one of the collection’s most coveted pieces. Gabrielle Union and Dwyane Wade, Amanda Seyfried, Greta Lee, and Lucky and Nara Smith were among those seated beneath the Armory’s vaulted ceilings, each in Tiffany & Co.
The evening’s most talked-about moment came courtesy of Mariah Carey, who performed for guests as the night wound down. By the time she took the stage, the dinner had dissolved into something closer to a concert with guests rushing toward the stage, diamonds and all.
Blue Book 2026: Hidden Garden is now available at Tiffany & Co. locations worldwide.
