Tiffany & Co. Unveils Blue Book 2026: Hidden Garden at Park Avenue Armory

On the evening of April 16, 2026, at the historic Park Avenue Armory,
Tiffany & Co. hosted an exclusive event to launch its
Blue Book 2026: Hidden Garden haute couture collection.
This is the latest creative achievement of Nathalie Verdeille and
Tiffany Design Studio.

Inspired by the tranquil transformations of nature, the collection skillfully reinterprets the legendary designs of
Jean Schlumberger. The beauty of these exquisite jewels was further enhanced by models wearing
Givenchy designs by Sarah Burton.

A Historic Venue Honoring Tiffany Heritage

The event was impressive not only for the jewelry but also for its historically significant venue.
Park Avenue Armory houses two of the last remaining intact interiors of
Louis Comfort Tiffany from 1881: the Silver Room and the Historic Veterans Room.

The choice of this space served as a testament to the traditional values and craftsmanship that
Tiffany & Co. has developed and refined over centuries.

The party brought together a star-studded guest list including
Rosé, Mariah Carey, Amanda Seyfried,
Naomi Watts, Teyana Taylor, Greta Lee…
