Very old Vintage tiny pearl oval brooch

Very old Vintage tiny pearl oval brooch. Discoloration and some tarnishing present. Please see pictures for condition. But otherwise sturdy and all tiny pearls in place. Unsure of whether pearls are real and unsure of metal type. But it is still a pretty and dainty and feminine piece! Thanks for looking! related tags: cottagecore grannycore 90s 1950s old school very old metal pin lapel casual preppy classic style
