I really like this bracelet. It is not hallmarked, but could be from Mexico. There are solid sterling balls all the way around. The bangle is heavy, weight is 40.4 grms. Inside diameter measures 2 1/4" at the widest point. I have a 7 1/2" wrist, and this bangle is hard for me to get on and off. The width of the top is almost 1/2". Condition is excellent. Lots of tarnish, but a silver cloth will take care of that. I would date this fine bangle at c 1950's-70's.
