Rosa grew up in Mannheim, Germany. After having graduated from high school, she went young and cheerful to Pforzheim to attend a goldsmith school and to study jewellery design. The years in Pforzheim not only taught her street credibility and a lot about questionable architecture of the postwar period, but she also learned technical skills with a growing passion for jewellery design. Her work is always characterized by special crafting techniques and materials, big expression and a pinch of humor.
