The piece has a matte silver finish throughout. No stones — the design relies entirely on the metalwork.\u003c\/p\u003e\n\u003cp\u003eThe construction style and silver-tone plating are consistent with 1970s–1980s costume jewelry production.\u003c\/p\u003e\n\u003cp\u003eThe 3 cm diameter is a restrained scale — works on a lapel, a shirt collar, or pinned to a scarf.
