Tiffany & Co has never been afraid to go deep. With the launch of Blue Book 2025: Sea of Wonder, the house dives headfirst into the unknown—an underwater world reimagined through high jewellery.
Designed by Nathalie Verdeille, chief artistic officer of jewellery and high jewellery, the collection strips the ocean of its mystery only to rebuild it in diamonds, enamel, tourmalines, and Schlumberger signatures. The result: surreal, sculptural pieces that sit somewhere between dream and discipline.
More than a tribute to the sea, Sea of Wonder is a masterclass in transformation. It draws on the archives of Jean Schlumberger, Tiffany’s visionary with a long-standing obsession with marine life, and reworks them with modern technique and sharper storytelling. “These pieces aren’t just about the ocean,” says Verdeille. “They’re about pushing what’s possible.”
Each chapter of the collection explores a different facet of life underwater. The Ocean Flora series opens with lush arrangements of Zambian emeralds and diamonds that float like sea grass in motion. The Seahorse pieces update Schlumberger’s 1968 brooches with fluted moonstones and a high-voltage mix of sapphires, zircons, and colored gemstones—graphic, intricate, and impossible to ignore.
The Sea Turtle designs are more than decorative. A standout pendant hides a clever mechanism that transforms it into a brooch—echoing the animal’s own amphibious journey. The surface is all engraved gold and diamonds; the construction is a feat of hidden engineering.
In the Starfish chapter, organic form meets high drama. Rubies from Mozambique, pavé diamonds, and 18k yellow gold collide in sharp, sculptural pieces with celestial weight. The Urchin designs turn to Schlumberger’s signature paillonné enameling, layering color and texture to echo the spiny beauty of their namesake.
Then there’s the Wave—the final act. Inspired by Schlumberger’s famous Leaves Necklace, this piece is anchored by over 17 carats of electric blue cuprian elbaite tourmalines channeling the force and elegance of crashing water.
If Sea of Wonder makes one thing clear, it’s that Tiffany & Co. still knows how to lead. The house isn’t just looking back at history—it’s rewriting it in bold strokes, gem by gem.
And as this new chapter unfolds, it’s a reminder that the real magic still lies just below the surface—if you’re willing to look.
