Art deco gilt iris glass stick pin

This beautiful faceted glass pin contains royal blue (almost purple) pink and green. It's gold plated over brass and 3 inches long. It is from the 1920s - 1930s, jewelry made in the 20s - 30s falls into the art deco time period. That makes this piece true vintage, possibly antique. There is a bit of plating loss where the pin would be in fabric. This one is hard to part with, I have loved it while it's been in my collection. Please check photos and feel free to ask questions. Thanks for looking ❤️
