Tiffany & Co.’s Sea Of Wonder Is A Masterful Interpretation Of Oceanic Treasures

There are jewellery collections that sparkle. And then there are collections that shimmer from somewhere deeper—a place of myth, memory and movement. Tiffany & Co.’s Blue Book 2025: Sea of Wonder is the latter. The diamonds aren’t there to simply dazzle—they draw you in like a current, pulling you below the surface into a world where marine dreams become jewelled reality.

Presented at an intimate gathering in New York this April, Sea of Wonder is not just a high jewellery collection—it is a layered, sculptural meditation on the ocean and its secrets. The collection, crafted under the creative direction of Nathalie Verdeille, Tiffany’s chief artistic officer of jewellery and high jewellery, dives boldly into the deep—both literally and metaphorically.

“This collection is a voyage,” Verdeille tells me as we sit over cups of matcha in a cream oasis of luxury in The Landmark building. “Not only into the ocean, but into the archives—into Schlumberger’s codes, his dreams, the very essence of his imagination. I wanted to channel his spirit, not copy his lines.”

The result is a collection that doesn’t merely pay homage to the past—it converses with it.

“This collection is a voyage into the depths of the seas,” Verdeille told me, her pale blue eyes and blonde hair glistening in the sunlight. Her glittery gold Dior suit is a fitting image of opulent luxury in this cream cocoon. “But also into the archives—into Schlumberger’s mind, his sketches, his codes, his obsessions. What I wanted to do was to let those inspirations flow through the lens of my own creativity and emotion, to let them evolve into something new, something poetic, something alive.”

The Seahorse Chapter: Memory Meets Motion

In Seahorse, the House revisits one of Schlumberger’s most iconic motifs. These new seahorses are dynamic creatures: moonstones shimmer with inner light, zircons and sapphires ripple with iridescence, and textures layer upon textures in sculptural crescendo.

“What I find fascinating is how Schlumberger always understood the emotional power of a silhouette,” says Verdeille. “So instead of being literal, I focused on the gesture of the seahorse—the way it curls, floats, hides.”

This sense of movement permeates the entire collection. Pieces don’t just sit on the body—they dance. “What I love about the seahorse is its paradox,” she explains. “It’s mythical and real, delicate and armoured. Schlumberger understood that duality. He made creatures with personality. My goal was to give them movement too.”

Sea of Wonder is Tiffany at its most elemental. It’s a collection composed in chapters, each devoted to a different marine motif. From the flora that sways beneath the surface to the glinting backs of sea turtles, from the jagged delicacy of urchins to the sweeping grandeur of waves, every piece tells a story.

It begins with Ocean Flora, a garden beneath the sea captured in a burst of colour and light. Here, Zambian emeralds—prized for their rich, verdant depth—appear suspended in fields of brilliant-cut diamonds. The impression is one of weightlessness, as though the stones themselves were drifting just below the water’s surface.

“I wanted to create pieces that felt as if they might float away if you weren’t careful,” Verdeille states. “There’s a delicacy to ocean flora, but also resilience. It bends, it moves, but it doesn’t break. I find that deeply feminine.”

Legacy Reborn

Jean Schlumberger’s presence hums gently through the entire collection—but never loudly. One of the 20th century’s most imaginative minds in jewellery, he had an extraordinary ability to turn nature into fantasy. He didn’t simply draw from the natural world—he transformed it, elevating sea creatures and coral into regal totems. His work, much like Tiffany itself, has always lived at the intersection of art and alchemy.

“He was radically modern in his time,” Verdeille expresses. “If he were alive today, he would be pushing us forward.”

Duality and Discovery

One of the standout chapters is Sea Turtle, which pays tribute to the ancient mariner through designs rich with texture and transformation. The shell—an iconic motif for protection, geometry and journey—is rendered in diamonds and engraved gold. One particularly breathtaking piece, a pendant that converts into a brooch, captures the turtle’s duality: land and sea, strength and vulnerability, stillness and movement.

“Transformation is central to this collection,” Verdeille notes. “I didn’t want pieces that only live in one moment. I wanted them to adapt—like the sea itself.”

This theme continues in Starfish, where rubies from Mozambique gleam alongside yellow gold and rose-cut diamonds in designs that blur the boundaries between earth and cosmos. These are not cutesy marine motifs—they are celestial, architectural and a little mysterious.

In Urchin, we find one of the most technical and poetic triumphs of the collection: paillonné enamelling. An age-old technique revived by Schlumberger in the 1960s, paillonné involves layering enamel over thin sheets of silver to create unparalleled luminosity.

“It’s an incredibly demanding technique,” Verdeille explains. “But the result—this depth, this light, this almost breathing quality—is worth everything. It reminds me of how light behaves underwater, always shifting, always alive.”

The Grand Finale: Wave

If Sea of Wonder were a symphony, Wave would be its crescendo. The chapter is anchored by a necklace that feels more like a living sculpture than an accessory. Cascades of diamonds are met with over 17 carats of vivid blue cuprian elbaite tourmalines—stones so saturated and hypnotic they seem to pulse.

“The tourmalines were a discovery,” says Verdeille. “Victoria Reynolds, our chief gemologist, brought them to me. Their colour—it was like the ocean. We didn’t build a design around them. We let them lead us.”

The Wave necklace evokes the rush of surf just before it breaks—fluid, immense, unstoppable. It’s not just a jewel. It’s emotion, carved and set with hundreds of water droplet diamonds.

High Jewellery as Art

Throughout our conversation, one word keeps surfacing: freedom.

Verdeille believes that high jewellery—true high jewellery—exists outside of trends. It is not about seasonal silhouettes or viral moments. It is about artistry, narrative, and permanence.

“High jewellery is not fashion,” she emphasises. “It is not disposable. It’s a form of creative heritage. And more than ever, women are looking for pieces that tell stories—about nature, about transformation, about themselves.”

She notes the resurgence of brooches, embraced not only by women but also by a growing masculine clientele. “It’s exciting to see these codes evolve. But if you look at Tiffany’s history, we’ve always been there. Jean Schlumberger was arguably the greatest brooch designer of the 20th century. This is not revival. This is the return.”

Timelessness in the 21st Century

So how does one make high jewellery feel modern today?

For Verdeille, it begins with trust. “We work with gems that are millions of years old,” she says. “We use techniques that go back centuries. And yet, we are designing for women who live in this moment. The bridge between then and now is imagination.”

“Women are no longer dressing for approval,” Verdeille observes. “They are dressing to express. High jewellery allows them to do that in a way that is intimate, powerful, and enduring.”

What makes Sea of Wonder so thrilling is not just its aesthetic or craftsmanship—it’s the emotional intelligence. These are pieces that understand the power of memory, the seduction of mystery, the beauty of contradiction. They are designed not for the gallery, but for the woman who wants her jewelry to say something lasting.

“The sea, after all,” Verdeille adds, “is not just beautiful. It is unknowable. It holds our fears and our dreams. That’s what I wanted to express.”

Final Reflections

As I walk through the viewing suite, the jewels glowing under soft lighting like relics of a sunken treasure, I am reminded of something Elsa Peretti once said: “To me, style is to be simple.” And in their own way, each piece in Sea of Wonder embodies a distilled, elemental truth.

These aren’t just jewels. They’re questions—about where we’ve come from, what we choose to carry forward, and how we adorn ourselves to face the future.

Tiffany’s Blue Book has taken us below the surface. And in the shimmering quiet of the deep, blue sea, they’ve reminded us that the most beautiful things often lie just out of sight—until someone dares to dive.
