Could be dated anywhere from the 20s to the 40's, when art deco was king. This is a wonderful large pin, and all of the many stones are in their original settings. I love the fact that there are a wide variety of stone shapes...rectangle, diamond, and rounds. No markings. . Pin measures 3" x 1. 75" x .50 "
