The House’s latest Blue Book collection explores the ocean’s depths through exquisite craftsmanship and vibrant gemstones.

Tiffany & Co. has unveiled its Blue Book 2025 high jewelry collection, Sea of Wonder, a luminous homage to the ocean’s depths and the House’s enduring legacy of design innovation. Conceived by Nathalie Verdeille, Chief Artistic Officer of Jewelry and High Jewelry, the collection draws inspiration from Jean Schlumberger’s iconic aquatic motifs, reimagined through a contemporary lens. Each piece captures the fluidity and mystery of the sea, blending intricate craftsmanship with a palette that mirrors the iridescent shimmer of underwater light and the bioluminescent dances of oceanic creatures.



Structured into six thematic chapters—Ocean Flora, Seahorse, Starfish, Urchin, Sea Turtle, and Wave—Sea of Wonder delves into distinct underwater worlds. Highlights include the Ocean Flora necklace, featuring vibrant Zambian emeralds set against a cascade of diamonds, evoking the lushness of underwater gardens. The Seahorse chapter revisits Schlumberger’s 1968 brooch designs with fluted moonstones and intricate arrangements of zircons and sapphires. The Wave necklace, inspired by Schlumberger’s Leaves Necklace, showcases over 17 carats of vivid blue cuprian elbaite tourmalines and diamonds, embodying the opulence of a crashing wave.


Sea of Wonder not only celebrates the ocean’s beauty but also reflects Tiffany & Co.’s commitment to pushing creative boundaries. By blending traditional techniques like paillonné enameling with modern design, the collection stands as a testament to the House’s dedication to craftsmanship and innovation. As Verdeille notes, these extraordinary pieces tell a broader narrative of the House’s love of pushing boundaries and the spirit of extraordinary savoir-faire that has defined Tiffany & Co. since 1837.
