Tiffany & Co. Presents the Summer Debut of Blue Book 2025: Sea of Wonder

Tiffany & Co. continues its exploration of the ocean’s majesty with the summer presentation of Blue Book 2025: Sea of Wonder, the House’s high jewelry collection designed by Nathalie Verdeille, Chief Artistic Officer of Jewelry and High Jewelry. Inspired by the mystery and magic of the sea—reimagining iconic Tiffany & Co. creations by Jean Schlumberger — the collection welcomes new creations in the Seahorse and Sea Turtle chapters.

Seahorse Purple Sapphire

“With the Sea of Wonder collection, we are charting new paths within the legacy left by Jean Schlumberger, taking a more abstract approach. Rather than revisiting his iconic pieces directly, we aim to embrace his philosophy and poetic vision, building upon his work to create an artistic movement at Tiffany that captures the spirit of Schlumberger’s aesthetic,” says Nathalie Verdeille, Chief Artistic Officer of Jewelry and High Jewelry. “If I were to distill this movement into a single idea, it would be the sea and its mysteries as an endless source of inspiration, explored through dynamic volumes and textures that suggest movement. With this collection, we have reinterpreted Jean Schlumberger’s work in a more conceptual way, gaining a broader perspective while diving into the depths of the underwater world.”

Sea Turtle Aquamarine Brooch

The Seahorse chapter reinterprets an iconic motif from The Tiffany Archives. Jean Schlumberger’s famed 1968 seahorse brooches serve as the inspiration for Verdeille’s evolved vision, one that imbues the marine creature with expressive texture and contrast. Unexpected pairings of colored gemstones—unenhanced purple sapphires, moonstones and blue sapphires—breathe new life into the motif. A striking necklace, requiring nearly 1,600 hours of meticulous craftsmanship, features more than 11 total carats of unenhanced purple sapphires alongside diamonds, moonstones and blue sapphires. This transformable design can be worn in three unique ways: the sapphire and moonstone necklace with or without the moonstone strand, or as a standalone moonstone strand.

In the Sea Turtle chapter, Tiffany & Co. reimagines archival brooches from Blue Book 1961, capturing the tranquil movement and sculptural shell of the marine creature. Aquatic tones of aquamarines and turquoise echo the sea’s palette, while diamond-encrusted forms lend dimensionality and depth. Expressed in a one-of -a-kind figurative brooch, the sea turtle is depicted in a series of modern masterpieces.

With each chapter, Blue Book 2025: Sea of Wonder continues to push the boundaries of creativity and craftsmanship, offering a poetic homage to the ocean’s most captivating inhabitants.
