This is a vintage bangle bracelet. It appears to be handmade sterling silver but is not marked so I do not know for certain. The bracelet measures 2-1/2 inches across the widest portion of the opening. It is 1/8 of an inch wide and weighs 16 grams. The bracelet is in very good condition but does have an age patina and could use cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
