Big pink rhinestone triple circle pin with a flower-like setting that holds the prongset rhinestone. The pin is unmarked but in very good condition. Measures 1 1/4" across. This pin comes in a Windsor Fifth Avenue jewelry box, although I cannot say for certain that the pin came in this box. Nonetheless, from my research, Windsor Fifth Avenue was a clothing store at 381 5th Ave., New York City in the early 1940s. The box is also in fairly good condition.
