Vintage Christian Dior necklace

I purchased this from someone who purchases high end estate jewelry from NJ and NYC. This is three gold tone chains attached with a wide clasp. This is from the 70’s. You will see the CD drop used at that time. Also Chr Dior was used as well and that is etched on the CD charm on back. This is a signed Paris bezel clear stone chain necklace. Each chain is a different length. One is 32, 34 and 36. This is a treasure. It does not appear to ever been worn. No tags or box. It is lovely. As much as I love it I know I will not be able to wear it enough. I love almost a paperlink look in between the bezel set clear stones. So beautiful. Enjoy
