Tiffany & Co. today unveils the fall expression of Blue Book 2025: Sea of Wonder, the House’s annual high jewelry collection designed by Nathalie Verdeille, Chief Artistic Officer of Jewelry and High Jewelry. This latest chapter continues the House’s exploration of the ocean’s boundless mysteries through nearly 40 never-before-seen designs. Reinterpreting archival creations by Jean Schlumberger, Blue Book 2025: Sea of Wonder brings renewed life to the visionary designer’s renowned works, celebrating the sea’s organic forms and fantastical beauty. The fall chapters—Anchor, Anemone, Ocean Flora, Shell, Urchin and Mermaid—complete the collection’s awe-inspiring narrative, weaving together exquisite craft, rare gemstones and poetic storytelling.

“We continue our exploration of this dreamlike underwater world with the fall expression of Blue Book 2025: Sea of Wonder,” said Nathalie Verdeille, Chief Artistic Officer, Jewelry and High Jewelry, Tiffany & Co. Each chapter—Anchor, Anemone, Shell, Urchin, Mermaid and Ocean Flora—offers its own moment of discovery, reinterpreting Jean Schlumberger’s marine inspirations with new visions of his aesthetic. It is a poetic expression of transformation, where the sea’s beauty is beautifully reimagined in modern masterpieces.”

The Anchor chapter reimagines Jean Schlumberger’s ruby, amethyst and pink sapphire brooch from 1939, a symbol of strength and symmetry. The new pendant, ring and bracelet—each centered around cushion-cut diamonds—define the collection with their timeless geometry. The Anchor pendant in platinum and 18k gold features a diamond of over 2 carats; the ring, a diamond of over 5 carats and the bracelet, a 1-carat diamond—all set with diamond accents that bring a luminous quality to each piece.

Drawing inspiration from Jean Schlumberger’s whimsical sea anemone brooches, the Anemone chapter teems with movement and imagination. The centerpiece is a striking necklace, animated with sculptural gold accents and diamonds, and brought to life with three unenhanced rubies totaling nearly 5 carats—sourced from the renowned mines of Mozambique, Africa. Prized for their remarkable color and quality, the rubies appear to dance within the design.

A celebration of form and texture, the Shell chapter explores the natural architecture of the sea. With undulating curves of platinum and gold and crests set with white and yellow diamonds, these creations invite a tactile experience. A remarkable Shell brooch features an 8.62-carat green tourmaline that captures the bold asymmetry of a conch shell.

Fusing the natural and the surreal, the Urchin chapter transforms the sea urchin’s radial symmetry into bold, ethereal compositions. The designs incorporate paillonné enamel—crafted using a labor-intensive technique from the 19th century—to evoke the urchin’s iridescent textures. The result is a luminous, layered surface that recalls the brilliance of ocean light.

Enchanted by the mythical figure of the mermaid, this chapter explores her allure through Nathalie Verdeille’s imaginative lens. A brooch in platinum, rose gold and diamonds depicts a mermaid in motion, accented by a black opal of over 10 carats at her fin. The motif continues in an expressive ring, earrings and necklace, each piece a tribute to an underwater fantasy.

New in the Ocean Flora chapter is a one-of-a-kind high jewelry timepiece, featuring a mother-of-pearl dial, a turquoise marker at the 12 o’clock position, and a diamond bracelet that echoes the motifs seen in this chapter’s high jewelry pieces.

The fall expression of Blue Book 2025: Sea of Wonder will debut on September 18^th at an intimate gala in Milan marking the culmination of this year’s Blue Book collection.
