Vintage Coro Boucher Signed Rhinestone Enamel Mom & Baby Birds In Nest Brooch

  

Signed Rhinestone Enamel Mom & Baby Birds In Nest Brooch. This brooch is signed, but I don't, know it, looks like Made. And an s in a star, very unclear, there is a Boucher almost the exact same but I think this is a period correct brooch by another maker, or made later by Coro?

Just don't know, in nice condition, lots of depth, enamel darn good with light chipping, it's got height and is 2 3/4" by 2 3/4".
