I need help identifying the maker of this copper and enamel pendant and matching earrings. The set has a bright orange background with raised flowers on the front. The backside of the set is also enameled. The pieces are of obvious high quality but I have not been able to identify the maker’s mark on the attached sticker. I’ve asked everyone I know in the vintage jewelry trade and still don’t know. If someone out there knows who this maker is, please email me! Thanks!
