Hello! I am new here and I have a question about my engagement ring. I love my ring and I feel bad asking about this because I am so lucky to have a ring like this, but on my diamond there is a feather that was marked by GIA but if I run my fingernail along it, it gets caught every time and it is very much external or surface reaching. My question is- is this normal? Should I get it repolished? I don’t want it to lose that much weight. If I look at it with my naked eye it is so small it can’t really be seen but under the loop it looks like a crack and I am scared one day it will cause my stone to break if hit wrong. Please let me know your thoughts I have attached images. Thank you so much
