About Petra Class
Petra Class looks to nature and the arts to compose her own masterworks, using gold and gemstones in rich hues to create jewelry pieces with elegant architectural qualities. Classically trained as a silversmith in her native Germany, Petra spent several years constructing tableware at a respected atelier in Berlin before opening her own studio there and subsequently in San Francisco where she now lives and works.
