This is a beautiful dangle necklace signed on the clasp: Raffaele Sterling. I can find no information about this company, but the necklace is good quality and circa 1950s - 1960s.
It has teardrop shaped faux pearls separated by aurora borealis crystal beads. Dangling from the middle is a larger teardrop shaped pearl with aurora borealis rhinestones.
It measures 16" with the drop measuring an additional 1".
It's in very good condition. Non-smoking household.
