Tiffany & Co. Goes Deep-Sea Diving in New Blue Book

New York—Tiffany & Co. unveiled its latest high jewelry collection Friday in New York at an event that was swimming with celebrities, including Oscar winner Mikey Madison and Golden Globe and Emmy nominee Greta Lee.

Titled “Sea of Wonder,” the 2025 Blue Book has six “chapters” focusing on underwater flora, oceanic creatures, and the movement of waves.

The chapters are: “Ocean Flora,” “Seahorse,” “Starfish,” “Urchin,” “Sea Turtle,” and “Wave.”

Tiffany & Co. Chief Artistic Officer of Jewelry and High Jewelry Nathalie Verdeille designed the collection, taking inspiration from Jean Schlumberger’s aquatic designs.

The collection “embarks on a surreal journey from the figurative to the abstract,” the brand said, reminding us that “the most beautiful things in the world often lie in the most unexplored and uncharted realms.”

The color palette seen throughout the collection—a mix of vibrant blues and greens—was chosen to mirror the iridescent shimmer of underwater light and the bioluminescent dances of underwater creatures.

“Each piece in our latest Blue Book collection, Sea of Wonder, captivates and invites us to lose ourselves in the rich storytelling as we embark on a journey though uncharted realms of the deep sea,” Verdeille said.

“Drawing inspiration from Jean Schlumberger’s fascination with the sea, our house’s pioneering spirit endures, driving us to reinvent archival inspirations from a modern perspective.”

The 2025 Blue Book opens with the Ocean Flora chapter, which focuses on plants.

Zambian emeralds are used throughout the chapter alongside diamonds, as seen in the earrings above.

The plant-focused collection transitions into the creatures of the ocean chapters, starting with the Seahorse.

When designing the seahorse, Verdeille looked to Schlumberger’s iconic brooches from 1968, intending to reinterpret his creatures with a contemporary twist.

The seahorses take form through an arrangement of colored gemstones including fluted moonstones, zircons, and sapphires.
