    Petra Class is the force behind a small exclusive jewelry design studio located in San Francisco, CA. Ancient goldsmithing techniques meld with contemporary sensibility to create jewelry that is both archaic and modern. Petra’s designs are owned by private collectors and museums throughout the United States and have won numerous awards. Her work has been reviewed in national and international publications on contemporary art jewelry. Petra’s collections are represented by major fine jewelry stores and galleries around the country. 

    Always playful, and anything but conventional, smaller everyday wearable pendants, rings, and earrings seem like precious little seeds next to the stunning collector pieces. 

    Signature elements in Petra Class’ work are the use of rough and refined gemstones set in timelessly modern designs of high karat gold. The interplay of textures, colors, and transparencies of those gems – diamonds, rubies, emeralds, sapphires, aquamarines, and tourmalines - are part of an ever-expanding palette and give her pieces an almost painterly quality. 

    Petra Class was educated in Germany. After studying art history and philosophy at the University of Stuttgart she pursued a rigorous traditional education in goldsmithing and design before moving with her husband to his native San Francisco. Her classical training and connection to the cutting edge European design world combine with the organic and nature inspired attitude of California to create Petra’s very own unmistakable vocabulary.
