Art Deco hair ornament with blue glass and sparkling marcasites in silver, made in France. Quintessentially Art Deco, this ornament has an open-worked silver plaque with three deep blue glass baguettes and abundant tiny marcasites in a geometric design. It is attached to a double hair pin that moves back and forth within the hinge. There are two French boar's head marks for 800-900 silver as well as Made in France on the reverse. It measures 2-5/16" by 3/4" and the pins are 2-1/2". The condition is excellent with no chips or missing stones. This stunning piece would make a great gift.
