Vintage Antique Made in Austria Gold Bar Pin with Citrine Paste Stones

This gorgeous pin is from the Art Deco period (1920s-1930s), and is in practically pristine condition! Could be used as a ladies brooch or as a men's tie pin, it appears to be made of real gold and has no discolorations or anything that would suggest it's not. Stamped "Made in Austria" on the back, at this time period many fine pins were made with 9K gold. The stones, clear and yellow rhinestones, are also known as "paste" when made of colored glass with a foil backing. The yellow in this case is a citrine color. The photographs are a bit darker than it appears in real life.
