Hi all, I apologize as I am new to this forum so I hope I asked in the correct place, and that I also do not know much on this subject. I have a ring that needs sized down 2 sizes, maybe a quarter size more. I was told that it could be done with no problem, but they would have to possibly oval the bottom of the shank. I'd just like to know if ovaling the bottom is very common. I've gone through a nightmare with my last ring so I'm very nervous. I do trust this jeweler, but I'd like to ease my mind as much as I can.
