For your consideration is this nice early signed Coro pave rhinestone brooch. Encrusted in pave rhinestones with a great Art Deco look. The metal appears to be pot metal which was common during the 1930s.
The pin measures 1 and 5/8 inches by 1 and 1/8 inches.
It is in excellent vintage condition with fully functioning hardware. The stones have nice fire and the pin is prettier in person!
