A Vintage Pair of Costume Jewelry Earrings Stud Back Pierced Mid Century Sparkly

This is an interesting pair of earrings with a gold tone base. Even the earring studs are a gold tone but I can't find any maker's marks. They have 3 greenish-blue stones in a triangle shape on the top, under that is a heart shaped rhinestone studded piece. I don't think the backs are the originals. These are very sparkly and would set off your evening attire perfectly. They are 1.5" long and .75" wide.
