Jean Schlumberger’s jewelry designs for Tiffany & Co. are already instantly recognizable. It is fitting that the revered luxury brand chose to put a colorful twist on some of his best-loved designs for its 2026 Blue Book collection. This year’s theme for the haute jewelry edition is “Hidden Garden.” Schlumberger’s visions are re-interpreted in unexpected groupings of astonishing gemstones.

According to Tiffany & Co.’s Chief Executive Officer, Anthony Ledru, “‘Blue Book 2026: Hidden Garden’ reflects our continued commitment to creativity, craft and the highest standards of gemology. This collection—one of Tiffany & Co.’s most important traditions for over a century—honors the legacy of Jean Schlumberger while demonstrating how we continue to evolve it for today’s high jewelry client. Under Nathalie Verdeille’s creative leadership, and in close collaboration with our gemologists and artisans, we are pushing the boundaries of design and technical excellence.”

The annual Blue Box collection takes its name from the first-of-its-kind catalog that Tiffany first published in 1845. That catalog inspired generations, and the creations in “Hidden Garden” continue that tradition. The organic new plays on familiar Schlumberger designs—such as Bird on a Rock, Paradise Bird, Parrot, Butterfly, Monarch, Marguerite, Bee, and more—make them brand new while dazzling the eye with serendipitously striking gem combinations.

Some of the highlights are three bright new versions of Bird on a Rock that are a natural fit for at least one set of lapels at the upcoming Met Gala, and an abundance of happy pink stones in keeping with the bucolic spring theme. “Hidden Garden” will continue to delight anyone lucky enough to add a piece to their jewel box long after 2026 is gone.
