Tiffany & Co. Debuts the Fall Chapter of Blue Book 2025

Tiffany & Co.’s most anticipated high jewelry tradition returns this fall with Blue Book 2025: Sea of Wonder, a dazzling continuation of the house’s oceanic odyssey.

From the moment Nathalie Verdeille, Tiffany’s Chief Artistic Officer, first spoke of “a dreamlike underwater world,” the expectation was clear: this collection would not settle for surface beauty. It would chart the depths. Nearly 40 new pieces emerge as modern talismans: where Schlumberger’s legacy meets maritime magic.

Verdeille’s vision is rooted in the archives of one of Tiffany’s greatest designers, Jean Schlumberger, whose marine-inspired fantasies made jewelry feel alive. For Sea of Wonder, she reclaims his language: seaweed curls, coral iconography, shell spirals; and translates it through a contemporary lens.

“This is a poetic expression of transformation,” she said. “Where the sea’s beauty is beautifully reimagined in modern masterpieces.”

Like a storyteller awakening an ancient world, Sea of Wonder is structured as six chapters: Anchor, Anemone, Shell, Urchin, Mermaid, and Ocean Flora; each drawing on Schlumberger’s iconography while venturing into new creative waters.

Anchor: Where History Roots the Sea

The opening chapter, Anchor, reaches back to a 1939 Schlumberger brooch, where rubies, amethysts, and pink sapphires clustered into an artful geometry. In Sea of Wonder, that same geometry is reborn: rings, bracelets, pendants in gold and platinum brim with cushion-cut diamonds. The anchor isn’t just a nautical symbol here; it’s the ground from which the rest of the underwater narrative flows.

Anemone: Movement Beneath the Surface

Venturing into Anemone, Tiffany summons the fluidity of sea anemones, and with it, kinetic jewelry. One highlight: a sculptural necklace featuring three unenhanced rubies from Mozambique. Each piece bends, bends again, as if caught in an eternal current. The collection murmurs: the sea is never still.

Shell & Urchin: The Architecture of Ocean Forms

Shell is a celebration of curling forms and natural symmetry. Platinum and gold wind in waves, kissed with white and yellow diamonds. A standout piece is an 8.62-carat tourmaline conch shell brooch, turning nature’s curve into wearable opulence.

Urchin turns stranger. Drawing on the 19th-century paillonné enamel technique, Tiffany conjures sea urchin spines with shimmering, layered hues that seem to glow from within. It’s structural, tactile, even scientific, yet entirely born of fantasy.

Mermaid: Mythic Seduction

In the Mermaid chapter, Tiffany leans into legend. A dramatic brooch in rose gold and platinum unfolds in scales, curls, and undulating lines. And at its heart glows a 10-carat black opal—a water-dark gem that anchors myth and matter. The mermaid becomes metaphor: not a fantasy to be tamed, but a mystery to be worn.

Ocean Flora: The Garden Underwater

The final act, Ocean Flora, brings us into Tiffany’s underwater garden. Here, flora unfurls across mother-of-pearl dials and diamond pavé bracelets. The pieces don’t just echo nature, they sprout from it.

Making its fall debut in Milan, Blue Book 2025: Sea of Wonder closed the year’s narrative with a flourish. Each piece is a wave, a creature, a whispered coral hymn.  And it asks us: will you dive? Will you let the sea reimagine you?
