The Tiffany & Co. Blue Book 2025 ‘Sea of Wonder,’ an extraordinary high jewelry collection that celebrates the allure, motion and mystery of the oceans. The collection is inspired by Jean Schlumberger’s legendary aquatic designs, diving into the depths, where the inexhaustible variety of flora and fauna transforms into an ethereal world of wonder.

“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.”

Each chapter of Blue Book 2025 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.

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.
