“The wealth of different reds found in nature, the sea of blues, the opacity of rough lapis, the transparency and subtlety of a lilac-colored sapphire, the glowing malleability of yellow gold – the materials allow for endless play and fascination.”
Petra Class Studio creates jewelry defined by the age-old techniques of gold smithing and hand forging. Featuring richly-hued rough and polished gemstones and crafted in 22K and 18K yellow gold with a delicate brushed finish, Class’ designs pay a modern homage to the adornments of antiquity.
Artist Petra Class, born and raised in Germany, pursued metalsmithing and design after receiving her BA at the University of Stuttgart. Class’ years training as a silversmith constructing tableware informed her approach to jewelry making, inspired foremost by the European tradition of applied art. Class’ son Lucas began working out of Brooklyn Metal Works in 2020, before establishing a private studio in Manhattan from 2022 to 2025. Based in San Francisco, CA, Petra Class Studio is a family-owned atelier run by Class, Lucas, and her daughter-in-law Phoebe, alongside several brilliant bench jewelers who assist in production.
