Help with necklace

[Steph]

I know nothing about jewelry, but I spontaneously bought this necklace from a used clothing store because it was unlike anything I had ever seen. It looks vintage, but I am not sure. It has no markings. It is pretty heavy. If anyone has any thoughts as to era and information about it (is it deco style?), I would be so appreciative. Thank you!!

Curious about this one. I believe it is a 70s does deco revival piece.
Let's see what others have to say.

I agree with Mary Jane, it has a very 1970s Deco revival look to it. It reminds me a little of a Pierre Cardin design.
