We estimate this ring size to be 15 1/2 (not to be confused with a baby's bracelet) as the ring is too big for our ring sizer!
We have included pictures of the ring next to a ruler in both mm and inches to assist with the size. And a big guy, needs a lot of gold- this weighs a hefty 11.7 grams.
It is in good vintage condition but for a ceremony, we recommend your jeweler buff out some of the light surface scratches/nicks.
