A piece of fine jewelry is, in many ways, an exercise in contradiction. It asks something formed by nature over billions of years to speak to a distinctly human moment; it transforms the irregular into the exacting, the emotional into something physical, the fleeting into something designed to endure. Yet few contemporary jewelers inhabit these tensions quite like SARAH & SEBASTIAN.
Founded in Sydney by Sarah Gittoes and Robert Sebastian Grynkofki, the Australian house has spent more than a decade quietly questioning the conventions of fine jewelry, the ways in which it can be made and, perhaps most importantly, what gives it meaning. Here, the natural world and the engineered exist in constant conversation. Ancient stones meet new technologies, deep-sea observations become sculptural forms, and traditional handcraft is pushed forward by an exacting approach to design.
As Sarah & Sebastian releases its latest bridal chapter, we speak exclusively with Gittoes about the ideas that continue to shape the house, from the strange beauty she encounters beneath the ocean’s surface to the invisible craftsmanship behind its most restrained designs, and why the most meaningful jewelry ultimately carries a story far greater than the materials from which it is made.
A Study in Duality
There is a certain restraint to Sarah & Sebastian that understates just how much is happening beneath the surface. Since founding the house in 2012, Sarah and Robert have resisted ornament for ornament’s sake, instead building a design language around reduction, experimentation and an eye for how an object works. Their instincts, however, arrive there from markedly different directions. “As a trained gemologist and diver, my design practice comes from observation, translating what I encounter in marine environments into sculptural form,” Sarah explains. “Robert’s background is industrial design and automotive engineering, so his instinct is structural, always thinking about how a piece is built with exceptional detail; how a setting holds, how something is engineered to last.”
It is in the space between the two that the brand has found its identity. “That duality really is the foundation of everything we do,” Sarah says. “We describe ourselves as a conceptual studio crafting new natural icons, engineered to inspire. The inspiration is elemental, drawn from nature and the ocean, but the execution is precise and rigorous.” Somewhere between those two impulses, the intuitive and the exacting, lies the particular tension that has come to define the house.
Beneath the Surface
In fine jewelry, the greatest feats of craftsmanship can be the ones that disappear. A diamond seemingly floats; a line of gold follows the body without interruption; a sculptural form feels so resolved that the complexity required to make it becomes almost invisible. It is this pursuit of effortlessness that has pushed Sarah & Sebastian toward innovation, not at the expense of traditional craft, but in service of what it can make possible. “We see technology as a tool that extends our craftsmanship rather than replacing it,” Gittoes explains. CAD modeling allows the team to interrogate proportion and mechanics before a piece reaches the bench, where it is still shaped, set and finished by hand.
That precision becomes more demanding, not less, as a design is pared back. “It’s easy to look at a minimal, sculptural design and assume simplicity, but that restraint is actually the hardest thing to engineer well,” Sarah says. Every decision becomes exposed: the selection of a stone, the tension of a setting, the proportion of a form, the quality of its final polish. Sarah likens the process to “the precision of a symphony,” where the success of the whole depends upon details the wearer may never consciously notice. “The craftsmanship is in what you don’t see as much as what you do.”
"From the selection of a natural diamond or gemstone through to the final polish, every stage is conducted with the precision of a symphony."
Forms from the Deep
To spend enough time underwater is to learn that perception is not entirely fixed. Light behaves differently, familiar forms become strange, and movement takes on another rhythm. For Gittoes, who has completed close to a thousand dives, these shifts have become inseparable from the way she sees as a designer. “Underwater, everything changes pace. Light bends and softens in a way it never does on the surface, and diving is quite meditative, you’re mindful of your breath, mindful of how you move, completely disconnected from the day-to-day.” It is within this altered state that Gittoes has learned to notice what might otherwise pass unseen: “The way kelp shifts in a current, how light illuminates sea jellies on the surface, or the mind-bending lifeforms you come across at depth.”
That relationship with the ocean has come to shape more than the jewelry itself. In 2022, Sarah & Sebastian established The Xanthe Project, a philanthropic initiative dedicated to ocean conservation, supporting research, education and advocacy through partnerships and creative projects. “Sometimes these things translate directly into a design, or inform the work we do as part of our philanthropic initiative, The Xanthe Project,” Gittoes explains.
A New Expression of Bridal
The house’s latest bridal collection unfolds across four distinct design stories: Urchin Lace, Freedive, Aether and Suspense, each exploring a different expression of the natural and engineered worlds that inform Sarah & Sebastian. Urchin Lace looks closely at the sea urchin, translating its spiked defenses and intricate natural architecture into lace-like arrangements of diamonds. Freedive draws on the meditative stillness of being suspended beneath the surface, while Aether turns to light, bringing natural diamonds together in intricate, constellation-like formations. Suspense explores another kind of tension entirely, using precise engineering to make individually set diamonds appear suspended, balancing architectural structure with the fluidity of the body. Together, the four stories move between the organic and the exacting, revealing just how differently a single design philosophy can take form.
The Alchemy of Nature
A diamond can be measured with extraordinary precision, yet some of what gives a stone its presence remains stubbornly beyond measure. Cut, color, clarity and carat can establish its technical credentials, but for Gittoes, they are only part of the story. “The four Cs will tell you a diamond meets a technical standard, but they won’t tell you if it has any personality,” she says. “I look for the way a stone plays with light, whether it feels alive rather than merely correct on paper. A diamond with individuality that a trained eye can see has more presence than one that’s textbook perfect.” It's an unusually human way of considering something so often reduced to a set of grades: individuality, rather than perfection, becomes part of what makes a stone exceptional.
That appreciation is also bound to the almost improbable conditions under which natural diamonds come into existence. Formed over billions of years under particular combinations of pressure, heat and time, no two emerge quite the same. Gittoes traces her fascination back to her gemological studies and learning about the rare alchemy needed for a gemstone to form. For a house that works exclusively with natural diamonds across its bridal collections, those traces of origin matter. “A natural diamond is proof that something rare and lasting can come from a moment of chance and that its imperfections are also what make it real,” she says. “I think the best relationships are formed the same way.”

A Personal Provenance
Perhaps what makes jewelry so enduring is its ability to hold meaning long after the moment that first gave it significance. For Sarah & Sebastian, an engagement piece begins not with convention, but with the people it is intended to represent. “Choose what feels authentically yours rather than what you think bridal jewelry is supposed to look like,” Gittoes says. “I always encourage brides to think about the story they want the piece to carry,” whether through a gemstone with personal meaning, an engraving or a silhouette that feels distinctly their own.
That sense of authorship extends to the house’s bespoke process, where the stone and alloy are considered in conversation with the wearer before the piece is handcrafted in their Sydney studio. It’s an approach that gives provenance a more intimate meaning: not simply where a material came from or how an object was made, but the particular sequence of people, choices and circumstances that brought it into being. In an engagement ring, those histories begin to overlap, the geological story held within the stone, the hands that shape it, and the relationship that gives it significance. Perhaps this is what allows jewelry to transcend its material value: its story is never complete at the moment it is made, but continues to be written by the life that follows.
