I totally understand, I'm one of those people that check everything under the loupe and 10/10 times I'll fine some minor imperfection

But I just learned to let it go if it's not very noticeable & doesn't bother me enough to ask for an exchange. Not sure if this will help you feel better, the last time I purchased a Cartier ring, I wore it out the very next day walking my dog. Out of nowhere my dog started sprinting when she saw a squirrel, this caused me to trip & fell with my palm & the ring hitting the concrete, leaving a very visible scratch on my ring. I took it in for polishing and it's barely noticeable now. If they can take care of a deep scratch I'm sure they can help you with the minor dents too.
