Tiffany & Co. has unveiled its Blue Book 2025: Sea of Wonder high jewellery collection, designed by Nathalie Verdeille, Chief Artistic Officer of Jewellery and High Jewellery. Inspired by the ocean’s boundless beauty, the collection features 40 never-before-seen designs that blend exquisite craftsmanship, rare gemstones, and poetic storytelling.

The fall chapters—Anchor, Anemone, Ocean Flora, Shell, Urchin, and Mermaid—complete this breathtaking narrative, each capturing a unique facet of the underwater world and reinterpreting Jean Schlumberger’s marine inspirations.

“We continue our exploration of this dreamlike underwater world with the fall expression of Blue Book 2025: Sea of Wonder,” said Nathalie Verdeille. “It is a poetic expression of transformation, where the sea’s beauty is beautifully reimagined in modern masterpieces.”

Anchor Chapter:
A reimagining of Schlumberger’s 1939 ruby, amethyst, and pink sapphire brooch, this chapter celebrates strength and symmetry. The Anchor Pendant in platinum and 18-karat gold features a diamond over 2 carats, while the Anchor Ring is set with a diamond exceeding 5 carats, and the Anchor Bracelet holds a 1-carat diamond—each accentuated with brilliant diamond details for luminous elegance.

Anemone Chapter:
Inspired by Schlumberger’s whimsical sea anemone brooches, the Anemone Necklace radiates movement and imagination. Sculptural gold accents and diamonds surround three unenhanced rubies totaling nearly 5 carats from Mozambique, prized for their vivid hue and exceptional quality.

Shell Chapter:
Celebrating the sea’s natural architecture, the Shell Brooch captures the undulating rhythm of ocean waves with platinum and gold curves set with white and yellow diamonds. At its heart lies an 8.62-carat green tourmaline, evoking the bold asymmetry of a conch shell.

Urchin Chapter:
The Urchin designs reinterpret the radial symmetry of sea urchins through bold, ethereal forms. Using paillonné enamel, a 19th-century technique, these creations shimmer with iridescent textures that mimic the play of light beneath the ocean’s surface.

Mermaid Chapter:
Drawing on myth and fantasy, the Mermaid Brooch in platinum, rose gold, and diamonds depicts a mermaid in motion, her fin adorned with a black opal over 10 carats. Complementary Mermaid Earrings, Ring, and Necklace continue this enchanting underwater motif.

Ocean Flora Chapter:
This chapter introduces a one-of-a-kind high jewellery timepiece with a mother-of-pearl dial, a turquoise 12 o’clock marker, and a diamond bracelet that mirrors the oceanic patterns seen across the collection.

With Blue Book 2025: Sea of Wonder, Tiffany & Co. continues its legacy of artistry and innovation, inviting admirers to dive deep into a realm where nature and imagination meet in luminous harmony.
