Will Stretched Ear Lobes Ever Shrink Back to Normal Size?

I was wondering if you would always have to get surgery after stretching your earlobes. I have heard from others that depending on how big you stretch them, they will shrink down but I want to make sure with a professional. I will attach a picture that shows the top size i would like to go to. So in other words, will they ever close up if ear lobes are stretched, if not will they ever shrink down to a normal ear piercing size like 18mm?
