This is just a gorgeous striking heavy pin made by Eisenberg in the 1940's. The workmanship is outstanding. Eisenberg used the highest quality stones from Austria provided by Swarovski. They are set into a white base metal. The purple stones are prong set and the clear ones bezel set. The largest purple stones measure 9/16" X 3/8" and the smallest one in the center 1/4" X 1/8". All of the stones are still very shiny and bright with no damage to any of them. The back is stamped Eisenberg Original. The S in a circle in the middle is the initial of the stone setter. The pin stem is slightly bent but the swivel clasp works perfectly. The pin measures 3.5" X 2". The stones are a true purple color. The photos are showing a little more red.
