Vintage Blue Plastic / Bakelite 3 Piece Jewelry Set

This is an old vintage bakelite or plastic and rhinestone jewelry set. It has a 15 inch necklace with goldtone metal, rhinestone and either bakelite or plastic five petal flowers. Then it has a 6 inch matching bracelet and screw back earrings. All these pieces are in excellent condition, all parts are working and no pieces are missing. There doesn't appear to be any wear to the metal either, but I don't know if they were ever worn as it is an auction item. They are unmarked and I an not sure of the date, but the screwback earrings tell me the are at least vintage.
