These lovely modernist earrings combine two elements that I love.....copper and enamel. The free form of the earrings and the dancing figures on the enamel are wonderful reminders of the mid-20th century. The backs of the earrings feature a screw back mechanism and the backs are signed Engstrom. These are a wonderful find from a renowned husband and wife team of jewelry artists. There is a tiny area of glaze loss on one corner of one of the earrings that feels like it happened in the production process.
