Tiffany & Co. marks the launch of its latest high jewelry collection, Blue Book 2026: Hidden Garden, with an intimate celebration in New York on the evening of April 16.

Designed by Nathalie Verdeille, Chief Artistic Officer at Tiffany & Co., in collaboration with the Tiffany Design Studio, Blue Book 2026 explores subtle transformations in the natural world. Each chapter revisits the work of Tiffany designer Jean Schlumberger, turning flora and fauna into sculptural forms through precisely matched gemstones and meticulous craftsmanship. The pieces were presented on models dressed in Givenchy by Sarah Burton.

The event took place at the Park Avenue Armory, where Louis Comfort Tiffany designed the Silver Room and the Veterans Room in 1881—two of the last surviving interiors by the artist, a nod to the house’s legacy.

The collection celebration welcomed notable attendees, including Teyana Taylor, Connor Storrie, Naomi Watts, Amanda Seyfried, Gabrielle Union, Dwyane Wade, Rosé, Greta Lee, Camille Cottin, Alison Oliver, Chase, Sui Wonders, Diane Kruger, Matilda De Angelis, Diego Boneta, Aron Piper, Caro Daur, Kelly Piquet, Lauren Santo Domingo, Hyun Joung Ko, Masami Nagasawa, Nara Smith, Antonella Roccuzzo, Valentina Ferrer, Maryam Al Falasi, Tianzhen Yang, Olympia of Greece, Phoebe Gates, Silvia Braz, and Yuqi Song all wearing Tiffany & Co. designs.
