Rare Patent Pearl Brooch And Earring Set

Rare Vintage Patent faux Pearl Brooch And Earring Set. I do not know the composition or the history as there is nothing similar to compare to. Purchased at an estate sale years ago with no history on the set. Set weighs 0.6oz.The backings are stamped with a Patent Number and no other identifiers. For safety sake I will list as gold tone and faux pearls. Heart shape earrings and brooch with gold tone flying bird center of brooch. Earrings are screw back style with threaded posts for adjustable & custom fit, which is one testament of their age. Set is in Mint condition for it's age and very rare as it is a patented design. Will come in box pictured. From a smoke free/pet free home.
