Well not broke, it's platinum and we had it sized up when we got it. They have to cut the platinum and add more platinum and then solder/buff it so the line doesn't show. I have noticed that the line was getting more noticeable the last few months. Today I noticed the crack is all the way through. Thankfully they sized it right in the middle on the bottom as my diamonds on the sides go almost all the way around.
Taking it in next week to get it redone. So if you have a platinum ring that you have had sized, keep an eye on it. I did some research and if you size it more than 2 sizes, this can happen.
