Rhinestone Vintage Necklace

I found this rhinestone necklace in a grab bag I bought a few month ago. It is in perfect condition: no missing stones or discoloration, perfect clasp etc., just some signs of very light wear The pendant looks like pot metal but I am not sure about the chain. Although both pieces seem to belong together, the metal of the chain might be different.
It looks a lot better in reality.

Thanks for looking:)
