Signed Coro Gold Tone Large Sunflower Clear Rhinestone Brooch

An estate piece recently arrived from USA.  Coro were in business in New York from 1919 until the late 1970's.  I would say this show stopper would have been produced during the 1960'S -  early 1970's.  It is in immaculate condition measuring 6cms across at widest point. Hallmarked Coro to the back, along with a firm tight pin closure.  A solid piece typical of the high quality of the Coro Company.   Gift boxed by Vintageonline.
