Age and value?

Hello, I came across this necklace and bracelet that my Grand mother used to let me wear as a child and was wondering how old it is and what it's value would be. I would also be interested in knowing it's provenance if that is a possibility. I have searched for hours but with no luck. I have included a couple of pictures. Thank you in advance, Stacey
