Query: Beautiful but unwearable

I bought these as part of my wife's Christmas gifts, but was unable to get them before Christmas. I thought they would look nice with the Byzantine bracelet I also purchased.They arrive very quickly, but when my wife tried to put them on, one of them has its post so large that she was unable to get it thru her piercing. I plan to return and exchange them for something with a little more quality control if its not too late. Otherwise she's stuck with them in her jewelry box, pretty but unwearable...
