Stunning 50,s choker necklace, brooch and earings

This is a stunning set that I bought in the early 90's, it came in origional box from well known department store in Uk. The store was very fashionable in the 50's. The glass beads are stunning and faux pearls are fabulous. I have always felt that the set which is unmarked could be by Dior. What do you think ?feedback will be much appreciated.
