Gold Washed Sterling Silver Ring Set with Golden Sapphire and Cubic Zirconia

Previously owned sterling silver ring with a bright gold wash. It is set with a large faceted golden sapphire. It may be a man-made sapphire. I tested it with a gem tester and it is corundum, but the tester does not know natural from man-made. White stones are cubic zirconia. Fleur di lis on the sides. Size 7 and the face measures 13mm wide. Weight: 11.9 grams. Needs a deep cleaning. Hallmarked inside.
