u/Lanky_Sundae1228

Thanks to this sub, bought these studs from Bhima for my mom with Mother’s Day making charges off offer on 10th of May. They arrived today. They are a bit too yellow for my liking but they look decent. The only problem is that back screw is not coming out. If I try any harder I’m afraid I’ll break something. And one of the stud has a blackish marking too.
Should I try to get this checked with a nearby jeweler or should I just return? What are my options?
Thanks!
