My fiance's hands are huge, and so are his fingers. He hasn't owned or worn any kind of ring since highschool. I was doing some looking online at different wedding bands and the largest size I could find (that told me the circumferance) was a 16 which was 77.4mm. I found a few size 17, but I'm not sure what mm that would be and I doubt it comes close. FI's finger measure about 87mm! I know a jewler could answer my question, but I was just wondering if anyone knew here what this means as far as finding a ring for him? Specially made? Just enlarging a smaller ring? Are we looking at a much pricier ring?
