Vintage 14K Yellow Gold Butterfly Stud Post Earrings Women?s CZ Stamped 14k Acid test performed to verify gold content. Tested for Diamond and my diamond tester did not confirm as diamonds. Most likely these are cubic zirconia. Measures approximating 6mmx6mm Still, a great rare pair of earrings. These were in my grandmothers belongings. She passed away 8 years ago and probably bought these in the 80s or received them as a gift. These have been cleaned and will come with the box pictured. I believe them to be in the original box. Marked $70 on price tag.
