Philosophy

The creations of SONNIA are more than just jewellery – they are an expression of personality and style. Each piece is handcrafted with the utmost care and attention to detail, designed to accompany you not just in the moment, but for many years to come. Whether for everyday wear, professional settings, or special occasions, SONNIA jewellery is versatile and distinctive, complementing any outfit and adding that special finishing touch. Timeless, individual, and always more than just an accessory.

Bespoke jewellery

SONNIA is intended for self-confident women who are looking for unique, high-quality jewelry that expresses their personality in all its beauty.
Designer Sonnia Dettmer is convinced that jewelry should first and foremost give pleasure and strengthen and emphasize the wearer’s self-confidence and full potential.

Sustainable handling of materials

SONNIA loves nature and it is her great concern to protect and preserve it. She therefore sources her materials, such as gemstones and corals, exclusively from trading partners who guarantee the sustainable use of natural resources. For SONNIA, this is not a trend, but the basis of her business concept and an expression of her connection with nature.
