Tiffany & Co. unveils the Blue Book 2026: Hidden Garden, a high jewelry collection that explores nature's most enchanting hidden worlds. Designed by Nathalie Verdeille, senior vice-president and chief artistic officer, Tiffany & Co., in collaboration with the Tiffany Design Studio, the collection explores the quiet, almost imperceptible transformations of the natural world. Each theme reinterprets the legacy of legendary Tiffany designer Jean Schlumberger, translating flora and fauna into sculptural silhouettes brought to life through exceptional gemstones and extraordinary savoir-faire.
It is Nathalie Verdeille's fourth Blue Book collection, to be unveiled in three phases: spring, summer and fall. The spring chapter debuted at a private gala in New York on April 15.
"Blue Book reflects our continued commitment to creativity, craft and the highest standards of gemology," said Anthony Ledru, chief executive officer, Tiffany & Co. "This collection — one of Tiffany & Co.'s most important traditions for over a century — honors the legacy of Jean Schlumberger while evolving it for today's high-jewelry client. Under Nathalie Verdeille's creative leadership, and in close collaboration with our gemologists and artisans, we continue to push the boundaries of design and technical excellence."
The spring launch centers on themes of transformation and renewal; nature's cycles guide the narrative. Organic growth and movement take shape through hand-formed gold vines, platinum leaves and structured geometric compositions.
Motifs of butterflies, parrots, bees and florals animate the collection. The Butterfly theme revisits a beloved Tiffany motif where unpolished sapphires in pink-orange and denim blue evoke the fragile beauty of wings.
The Monarch theme draws on a Jean Schlumberger necklace featuring a hidden butterfly, reimagined with twisting vines, sculpted foliage, handcrafted platinum, 18k yellow gold, and pavé diamonds.
In the Bird on a Rock story, the iconic design takes flight once more, perched on magnificent cushion-cut aquamarines in vivid Santa Maria blue from Brazil. Custom-cut chrysoprase beads add a lush green contrast, while a transformable necklace set with a 22-carat aquamarine and a pair of animated birds can also be worn as a brooch.
The Parrot theme draws inspiration from Schlumberger's 1960s brooches, reimagining their playful spirit through a vivid interplay of color and texture. Unpolished blue and purple sapphires animate whimsical feather motifs, while diamonds and finely executed paillonné enamel lend a painterly richness to the composition.
The Bee theme, inspired by Schlumberger's Two Bees ring, explores honeycomb lattices and fluid, organic movement.
