I'm not sure if this is a silly question or not. Is it ok to use a 14kt gold friction back on a stud earring with an 18kt gold post? Could the 14kt back possibly damage the 18kt gold post? Both the friction back and the earring are in white gold, if that makes any difference. I'm asking because I recently ordered jumbo backs for my studs, and I didn't realize until just now that they're 14kt.
Thank you!
Thank you!
