Tiffany & Co. Unveils Blue Book 2023: Out of the Blue —A World of Aquatic-inspired High Jewelry That Celebrates Jean Schlumberger’s Legacy

NEW YORK, NY—Tiffany & Co. announces the debut of Blue Book 2023: Out of the Blue, the latest expression of Tiffany’s esteemed high jewelry collection. As the first Blue Book collection designed by Nathalie Verdeille, Tiffany & Co. Chief Artistic Officer of Jewelry and High Jewelry, the extraordinary designs celebrate Jean Schlumberger and his fascination with the sea’s fantastical creatures. With geometric and stylized aesthetics, each masterpiece draws inspiration from the legendary designer’s imagination and design philosophy—perpetuating and reinventing Schlumberger’s enigmatic symbols of the sea.

“With Blue Book 2023, we saw an opportunity to honor Jean Schlumberger’s legacy by giving new life to some of his most celebrated designs,” said Anthony Ledru, Chief Executive Officer, Tiffany & Co. “These creations have a distinct Schlumberger quality and personality to them, but the designs are all new. We are certain that he would have been as pleased with each masterpiece as we are.”

The collection will debut in two phases over the course of 2023 with various themes embodying aquatic life. The summer collection will launch with seven distinct themes: Shell, Coral, Jellyfish, Pisces, Starfish, Sea Star and Star Urchin. The Shell theme explores the three-dimensionality of objects sculpted by the ocean. One of the most versatile designs within Shell is a transformable pendant featuring a detachable diamond brooch that reveals a stunning black opal of over 21 carats. The Coral theme is defined by exuberant hues and features an array of designs showcasing tanzanites, sapphires and yellow diamonds. Ethereal and luminescent, a striking brooch from the Jellyfish theme echoes the graceful movement of a jellyfish’s tentacles.

The Pisces theme is a study of the sea, a representation of an unknown, infinite world that fascinated Jean Schlumberger. With suites featuring exceptional unenhanced padparadscha sapphires, Umba sapphires and diamonds, this theme offers warm hues to complement the cool blues of the ocean. The Star Urchin theme offers a study in symmetry and form. Embodying the drama of the ocean, these designs are characterized by tanzanites and hand-carved chalcedony which emulate the sea urchin’s spiky exterior.

An iconic silhouette of the ocean, the Starfish theme reimagines the familiar creature as if tangled between rocks with opals, aquamarines, tourmalines and beryls with diamond accents. A diamond-intensive suite offers a unique expression of this sea creature. Moreover, the Sea Star theme features a field of custom-cut mother-of-pearl starfish entwined in coral-inspired motifs, providing a snapshot of the sea’s fascinating ecosystem. Exceedingly rare padparadscha sapphires, Umba sapphires, mother-of-pearl and carnelians bring the Sea Star theme to life.   

“In Jean Schlumberger’s imagination and design philosophy, the sea represented an unknown, infinite world. He choreographed unparalleled manifestations of its majesty and mystery,” said Nathalie Verdeille, Chief Artistic Officer, Jewelry and High Jewelry, Tiffany & Co. “My first Blue Book collection for the House is a deep dive into aquatic life that both honors and reimagines Schlumberger’s vision.”

Blue Book 2023: Out of the Blue will debut this summer at an exclusive high jewelry celebration at The Landmark, the newly reopened Tiffany & Co. on Fifth Avenue.
