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 “Seahorse” brooch, which also can be worn as a pendant, features more than 12 carats of blue zircons, sapphires, moonstones, and diamonds set in 18-karat yellow gold and platinum. (Image courtesy of Tiffany & Co.)
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.

The “Sea Turtle” pendant has a more than 4-carat diamond at the center of its shell. It is crafted in platinum with 18-karat yellow gold accents. Sapphires are seen as well, representing the reptile’s eyes. (Image courtesy of Tiffany & Co.)
The Sea Turtle chapter showcases the reptile in both its literal form and through necklaces with intricate gold engravings designed to mimic the geometric pattern of a turtle’s shell.
A highlight of the chapter is a pendant that reflects a turtle’s journey when it first hatches from an egg on the beach and must journey across the sand to get into the sea.
The pendant does this via a hidden mechanism that transforms the piece into a brooch.
The “Starfish” pendant features more than 3 carats of unenhanced rubies accented by diamonds in platinum and 18-karat yellow gold. This pendant also utilizes a hidden mechanism to become a brooch. (Image courtesy of Tiffany & Co.)
The Starfish chapter turns the marine animal into high jewelry with celestial overtones, said Tiffany & Co.
Here, the starfish are seemingly frozen in motion. Unique cutting techniques were used on Mozambican rubies and diamonds that were then set in 18-karat yellow gold and platinum.

Moving on to a fellow echinoderm, the Urchin chapter embodies sea urchins and the texture of the animal’s spikes.
Some of the pieces in the chapter use Schlumberger’s Paillonné enameling technique that he created in the 19th century to add a delicate yet thorny texture to designs.

Waves is the final chapter of Tiffany & Co.’s 2025 Blue Book.
It is a celebration of the movement of the ocean, with powerful, sculptural designs inspired by the voluminous form and dynamic motion of Schlumberger’s “Leaves” necklace.
Blue Book 2025: Sea of Wonder debuted on April 25.
