Petra started her career in 1988, in Switzerland, her native country. During her 4 years apprenticeship, she learnt a variety of different jewellery making techniques, and studied gemstones, metals and design. After her training, she worked in small studios to perfect her craftsmanship. One of these jobs led her to Canada.
Falling in love with Montreal, she decided to stay, and started to create her own designs jewellery. Most of her pieces are one of a kind, constructed in precious metals, adding sometime gemstones.
Her openness to and her awareness of daily occurrences become her source of inspiration that she translates into minimalist and abstract jewellery.
