About SONNIA
As the founder and designer of SONNIA Jewellery Design, my passion for jewellery goes far beyond creating accessories – my goal is to highlight the uniqueness of every woman.
Inspired by the beauty of nature, the vastness of the sea, and the power of colour, I craft each piece with utmost precision and deep attention to detail. Sustainability and a respectful use of materials are at the heart of everything I create.
My mission? To make women shine – from the inside out.

“For me, designing means creating a truly unique piece of jewellery every time – a symbol of style, individuality, and timeless beauty. With my designs, I aim to evoke a feeling that captures the fresh breeze of the ocean and brings the magic of the moment to life.”
“Can you feel the ocean breeze? Through my designs, I strive to capture a way of life that echoes the rhythm of the sea and makes the magic of the moment come alive.”
During a long sailing trip, I discovered the fascinating treasures of the sea – coral, pearls, and shells – whose natural beauty and depth left me truly enchanted.
These precious gifts of nature have since become an essential part of my creations, lending them their distinctive elegance.
My logo, featuring two harmonious waves forming the letter “S” for Sonnia, symbolizes the perfect fusion of nature and creativity.
With a trained eye, a deep love for detail, and a profound appreciation for the finest materials, I have been creating jewellery for over 25 years – pieces that highlight the unique beauty of every woman.
My sense for aesthetics and the extraordinary has led me to renowned jewellery exhibitions across Europe and earned me international recognition.
Since 2005, I have been living and working in the idyllic town of Merano in Northern Italy. In my elegant showroom, I warmly welcome clients to explore the world of my designs.
Here, exclusivity, aesthetics, and personalised consultation take centre stage – always with the aim of creating jewellery that touches the heart.
