This is an old vintage signed Oscar De La Renta stunning 2 1/2" by slightly under 1 3/4" by 1/2" wide pin from local high end estate.  Excellent well cared for condition. Features a dangling faux pearl, black stone and sparkly rhinestones set in bright gold tone. Under a loupe all I could find is a 2mm microscopic nick or dip to the black stones back side edge not worth me noting. May be in the making of the pin and not worth me even noting. See my last two photos. Fabulous pin in well cared for condition. Thanks for looking.
