This happened to me with a tourmaline last summer. It was definitely sent through a stamper and broke the culet point off my stone. It is so frustrating when this happens! It was one of a kind so I couldn’t just return it.
I would look them over really well and maybe bring them to your jeweler before they are set. If it was the center, I would say definitely but the side stones might need a professional opinion since they are so small. The jeweler should be able to tell you if you should exchange them.
I think your proporations for your stone look great. They don’t over power your center stone and they always looks a little larger when set.
