This lovely bangle is Chinese plique a jour enamel. The enameling is done similar to cloisonné enamel. The difference is that there is no metal backing on the plique a jour so the enameling creates a stained glass effect. This bangle measures 5/8" wide and 2-1/2" inside diameter. The base enamel color is a beautiful teal blue. The bangle has pink flowers with green leaves. These are very nice colors for spring.
