When I put this on it was very hard for me to go ahead & list this one...as many...I love it! It's all sterling silver that weighs 33.7 grams, nice weight not to heavy & not flimsy. Signed A & Sterling. The inside measures 5 5/6" & the opening 1 1/16". Will fit loose on a 6 1/2" wrist & tight on an 8". It has a little give to it so could do very slight ajustment. It is at it widest point 1" & narrows down around the back side to 5/16".
