My unsolved Mystery Piece

This Necklace and Earring Set has Glass Jet Black Rhinestones accented with AB Rhinestones in Gold tone setting has been a mystery I think it maybe a Juliana Piece but clearly the earrings are different style from the necklace but was worn together picked this up at an estate sale and it looks stunning on! Just adore it have worn it a few times to events just one of my wonderful pieces that I enjoy!
