This is a beautiful vintage Art Deco ring in sterling silver set with an oval faceted citrine. The ring is unmarked except for a maker's mark that I haven't been able to identify but it acid tests for sterling. The stone, which is slightly over 1/2 inch north to south has been tested with a gemstone tester and tests as citrine. It is a very lovely stone with a rich color.
It is a size 7 1/2 and it is in very good condition.
