Bright lime enamel gives Daria Salus's thistle design a cheerful little jolt. The enamel is made by layering powdered glass over copper and firing it in a kiln, then paired with sterling silver. The lime color makes the thistle feel cheerful, graphic, and anything but traditional. Lime Enamel Earrings With Sterling Silver - thistle feels unmistakably handmade, but Daria Salus keeps the result polished enough for everyday use or wear.
