This is a lovely vintage Art Deco era filigree bracelet in a rhodium finish with three emerald green glass stones. It is a bangle style with a slide type catch. It is marked, but I have not been able to identify the maker.
The interior measurement is approximately 7 inches and it will fit an average wrist. Note that the way the fastening works requires that you slip it over your hand to put it on. If you have larger hands this might be a tight fit. It is about 1/2 inch wide and it is in very good condition.
