I've been trying to find out when, where & by whom this was made by for years.

These belonged to my great grandmother. As far as a story or history behind them goes, she never said. She used to let me play with her box of jewelry with her supervision when I was a kid. I ended up with it after she died. I've never considered parting with any of it but I've always been curious as to when it was made, where it came from & If any of it was real or not. The necklace REALLY has me CURIOUS. I can't find ANYTHING remotely similar anywhere.
