The inside circumference—including the "gap" of this attractive Navajo cuff—is seven inches. It is not real thick gauge (nor is it thin) Sterling, so it can adjust in or out a little. The wearer needs a wrist circumference from a 6.75-inches to maybe 7 and 1/8th-inches. This cuff is almost 1.75-inches across at the top stone—which is the longest of the 11. The smallest two stones on each end are one-half-inch. The turquoise is either Royston or Kingman. It has a few years on it so the color of the stones may have changed a bit. Weight is 57-grams, or 2-ounces. This cuff is quite a bargain, and would be priced considerably more if it had thick gauge Sterling. It is still very substantial, though. It has several "Sterling" stamps, and another obscured stamp; not sure if that is the hallmark. Always complimentary Priority shipping within the U.S.
