Mid-Century Amerique MOP w/ Rhinestone Accents Brooch & Clip-0n Earrings

Mid-Century Amerique brooch and clip-on earrings set with round mother-of-pearl (?) and accented with clear rhinestones in a gold tone open setting. The brooch has a cascading spray or leaf shape with a gold tone bow. The earrings are round with mother-of-pearl in a filigree setting. The brooch measures 2 1/4 inches by 1 1/4 inches. The MOP have a four-prong setting and the rhinestones are in a rim setting. The brooch has a rollover over clasp in very good condition. The earrings measure 15/16 inch diameter with 3 MOP stones and are clip-on. All of the MOP stones measure 1/4 inch diameter. The brooch is marked AMERIQUE. I could not find the mark on the earrings. I am not an expert on identifying jewelry stones or beads so I can not guarantee that this is real mother-of-pearl. It could be lucite (?). Please view all of the pictures and if you have any questions, please let me know. This set is in very nice condition. JB 006-15
