These vintage articulated or door-knocker earrings are very well made. They are made of sterling silver in an articulated design and set with a round cabochon at the top and a horizontal oval cabochon at the drop.
The measurements are approximately 1 3/16" tall by 11/16" at the widest point on the drops. The deepest point is at the center of the oval cabochon at almost 1/4".
Studio-made by an anonymous artist, they are marked simply 925. Estimated to date from the 1980s and in excellent condition.
