Brooch & Earring Demi Sets.

A few of my recent finds. I'm in love with the black & white set! Unsigned but reminds me of some Weiss. The enameled flower is signed Coro & the earrings are married to the brooch. The brown beaded set is signed Japan, enameled floral set signed Austria. The butterfly set is unsigned but I think its a Weiss set. Thanks for looking.
