Studio
At SONNIA, jewellery design is an art form that unites aesthetics and craftsmanship. In her studio, timeless one-of-a-kind pieces are created – inspired by the endless diversity of nature.
Materials such as coral, pearls, shells, and precious stones are transformed into truly unique creations. The creative process begins with a sketch and flows through prototype development to the final piece.
With precision and a deep sensitivity for materials and form, each design becomes a tribute to nature and a refined expression of individuality.

“Made by SONNIA”
– stands for exceptional design, superior quality, and timeless elegance.
Whether it’s a bespoke creation or a redesign – we bring your vision to life with precision and passion. For true connoisseurs of the extraordinary, we also craft luxurious haute couture designs that impress with their uniqueness and artisanal perfection.
“Nature’s treasures inspire me time and again. In my jewellery, they take on a new meaning – becoming unique companions that celebrate the individuality of the woman who wears them.”
