Vintage Art Deco Dress Clips Silver Tone Rhinestone

Lovely pair of vintage art deco dress clips. Unmarked. They each feature a single rhinestone in the center. The metal is silver tone and soft, maybe aluminum, pot metal? Good used vintage condition with some wear due to use and age. The metal is soft and bends easily so the two are not even. There is rusting/tarnishing at the hinges. One stone has darkened more than the other.
