wedding rings.

Recently one of my family members is getting married and he bought a wedding ring and it’s around 9K- and ig I’m not really experienced in these things so I looked at him like “wtf” and he said it’s on the cheaper side for a wedding ring… another said that her ring was 20k-

Idk man I think I’m going insane bc personally- I don’t trust myself to wear smt so expensive… like wdym I’m wearing 12K on my finger rn?!

What do you guys think?
