This is a wonderfully eclectic repurposed jewelry brooch. I can see several vintage elements combined into one piece: red rhinestones, a red enamel flower, a blue cabochon stone, a shell motif, a pearl-like bead, and a dangling charm, all arranged into a rich collage. The back is marked “RED HAT”, which gives it a playful, whimsical personality and suggests it may be inspired by the Red Hat Society theme.
