About Sonnia

Sonnia Dettmer is a jewelry designer by passion. She loves nature and its materials, especially the richness of shapes, the immensity and the beauty of the sea. Sonnia Dettmer makes this so directly tangible in her creations that you think you can hear the sound of the sea and breathe in the fresh ocean air.

“Designing to me means always having the most beautiful piece of jewelry in mind.”


During a sailing trip in 1990, Sonnia fell in love with the treasures of the sea, corals, pearls and shells, which to this day, along with precious stones, are distinctive features and an integral part of her collection. Two waves that meet form the logo of “SONNIA”. A symbiosis between the individuality of nature and the creative power of the designer.

With a great love for her materials and a trained eye for detail that draws from years of experience in jewelry design, Sonnia creates uniquely beautiful and extraordinary jewelry for special women. Sonnia’s eye for aesthetics, for the particular and the beautiful, brought her success at exclusive jewelry exhibitions throughout Europe, through which she achieved international fame. In 2005, the designer moved her business and residence to northern Italy and offers her clients an exclusive and personal consultation in her showroom in Merano.
