This is a vintage circular brooch dating to the 1950's. It has an open design with an inner circle of crystal chaton rhinestones and an outer circle of small navette stones in a pinwheel design. All stones are prong set. The stones are brilliant. The frame has a silver tone finish. The closure is an unusual safety locking clasp that opens half way and will close again if pushed to the back. The clasp will be locked both in the front and back. The pin stem has a bend but functions fine. Size is 1 1/2 inches in diameter.
