I bought this set many years ago. This set had a paper label (which is now gone) that said Paris and the designer’s name “Orena Paris”. We suspect the necklace was made just before World War II in a silver tone aluminum. It has an industrial simplicity design, yet an elegant look to it. The latch of the necklace has a deco style hook. The necklace is 18” and the center drop is 6” long. It’s light and comfortable to wear. The matching clip earrings are 1” x 1”.
