This is a fabulous vintage bracelet. It's hinged and has a safety chain. The beads are glass in two sizes of muted green. They are set over gold tone metal. This bracelet has no marks or hallmarks but it is consistent in style and construction to bangles by Miriam Haskell.  The bangle bracelet is just under 3/8" wide and has an inside diameter of 2 1/4." The bracelet fits a small to average sized wrist.
