Rhodium Plated Rhinestone Circle Vintage Brooch

This amazing vintage brooch is probably from the 1930s or 1940s. It is rhodium plated pot metal with a patina of age, but still in excellent condition. Seven rhinestones, all intact.  The circle clasp is in good working order. This piece is not signed.
The brooch measures just shy of 2 inches in diameter. This would be a terrific addition to any vintage costume jewelry collection!
