This is an outstanding three strand vintage pearl and rhinestone rondell set with matching earrings circa 1955.  The short choker is in excellent condition with prong set rhinestone rondells set between faux pearls that graduate in size from 9mm in the center to 5mm at the ends.  This would make a stunning necklace for a bride.  It would also look fantastic against a black cocktail dress.  It has a hook clasp for a string of pearls closure and measures 12 1/4" without the clasp.  The string of pearls clasp adds another 3" to the length.  The matching earrings are dangling clusters of faux pearls and rhinestone rondelles that are riveted to their backing and hang from a clip back earring.  They measure 1 1/4" in diameter.
