This sterling silver necklace looks to be Mexican made but is only stamped 925 and nothing else. It is made up of graduated panels with hinges in between. The largest center panel measures 1.25" X 5/8" and they graduate down to 3/4" X 1/4". The closure is a tab in slot style with the loop that goes over the tiny bead. It is stamped 925 on the clasp. The weight is 41.70 grams and the length is a little less than 18". I polished it up some but it could use more.
