Fern fronds, but make them aqua. Daria Salus creates these enamel earrings by layering powdered glass over copper and firing each piece in a kiln. Handmade in the Bay Area with a bright botanical look. The aqua enamel keeps the fern motif fresh and graphic rather than delicate. In Aqua Enamel Fern Earrings, Daria Salus lets the shape, color, and materials carry the design.
