Ciro '50s Vintage Hollywood Regency Circle Pin

Ciro began making popular costume jewelry just before the roaring twenties. By the 1950s, they became ladylike. This is a variation on the popular '50s circle pin. I call it Hollywood Regency because the shape and detailing is so mid-century and glamorously architectural. The pin is in excellent condition for it's age and is stamped CIRO on the bottom (see photo). It measures 1-1/4" diameter.
