Beautiful in good condition as expected with the age. One the gemstone tester it tests as Aquamarine. Beautiful colour mint pale green. The stone measures approx 1.5x1.2cm and the bar approx 6cm. It is not hallmarked but it's silver. I sell it as white metal. I didn't clean it comes as seen. Thanks for looking:-)
