Here is an artist made cloisonne enamel pendant. The wire used to separate the different colors of enamel looks to be gold. The enameling looks like there is foil on the back. The enamel part is set into a gold 1/16" border. It looks like it was then attached to a silver base which is textured with cross hatch marks. There are no hallmarks on this pendant but I believe it to be sterling silver and gold or at least sterling vermeil. I don't think that an artist would go through all the work of the enameling and not use fine metals. There is a signature on the back but it is very hard to see. It measures 1 1/8" X 3/4". Excellent condition.
