Tiffany & Co. today unveils Blue Book 2025: Sea of Wonder, an extraordinary high jewelry collection that celebrates the allure, motion and mystery of the oceans. Designed by Nathalie Verdeille, Chief Artistic Officer of Jewelry and High Jewelry, the collection embarks on a surreal journey from the figurative to the abstract—inspired by Jean Schlumberger’s legendary aquatic designs.
Blue Book 2025: Sea of Wonder dives into the depths, where the inexhaustible variety of flora and fauna transforms into an ethereal world of wonder. With an evocative color palette that mirrors the iridescent shimmer of underwater light and the bioluminescent dances of oceanic creatures, the collection reimagines the beauty of the deep through Verdeille’s creative lens.
“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 through uncharted realms of the deep sea,” says Nathalie Verdeille, Chief Artistic Officer of Jewelry and High Jewelry.
“While each creation weaves a story of the ocean and its wonders, these extraordinary pieces also tell a broader narrative of the House’s love of pushing boundaries, our relentless pursuit of that which has never been done before, and the spirit of extraordinary savoir faire that has defined Tiffany & Co. since 1837. 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.”
Each chapter of Blue Book 2025: Sea of Wonder delves into a distinct underwater world evoking everything from the vibrant flora and elusive creatures to the dramatic movement of the waves. The House’s legacy of inventive design and craftsmanship permeates every piece, blending complex artistry with natural inspiration to create a collection that is as emotive as it is awe-inspiring.
The collection begins with the lush world of oceanic plants, captured in delicate designs that call to mind an underwater garden. Notable pieces from the Ocean Flora chapter include a necklace with magnificent Zambian emeralds—celebrated for their rich, verdant hues—that seemingly float atop a garden of diamonds. The Seahorse chapter, inspired by Jean Schlumberger’s iconic 1968 brooches, reinterprets these creatures with a contemporary twist. Fluted moonstones and an intricate arrangement of colored gemstones, including zircons and sapphires, create texture and contrast, bringing these mythical beings to life with both elegance and complexity.
The Sea Turtle designs feature diamond-rich patterns and intricate gold details. The geometry of the turtle shell is beautifully sublimated by Tiffany artisans, who meticulously engrave each piece. A standout design, the Sea Turtle pendant, features a hidden mechanism that transforms the piece from pendant to brooch, reflecting the turtle’s journey from land to sea. The Starfish chapter deconstructs and reinterprets the graceful creature into high jewelry with celestial overtones.
Utilizing unique cutting techniques, each piece offers sculptural complexity, with rubies from Mozambique and diamonds accented by 18k yellow gold, rose-cut diamonds and pavé diamonds. The Urchin chapter draws from the intricate forms of the sea urchin, amplified through Jean Schlumberger’s visionary approach. Paillonné enameling—a 19th-century technique that Jean Schlumberger is credited with revitalizing—adds a delicate, thorny texture to the designs while capturing the iridescent essence of the sea.
Lastly, the Wave chapter celebrates the dramatic movement of the ocean through powerful, sculptural designs. The breathtaking Wave necklace evokes the opulence of a crashing wave, featuring diamonds accented by vivid blue cuprian elbaite tourmalines of over 17 total carats. The piece is inspired by the voluminous forms and dynamic motion found in Schlumberger’s famous Leaves Necklace.
As Blue Book 2025: Sea of Wonder reimagines the hidden wonders of the ocean, it reminds us that the most beautiful things in the world often lie in the most unexplored and uncharted realms. This collection is a testament to Tiffany & Co.’s commitment to creativity, craftsmanship and a deep reverence for nature’s infinite mysteries.
The House will unveil the spring iteration of Blue Book 2025: Sea of Wonder at an intimate event in New York City on Friday, April 25.
