Antique Czech Art Deco Brass Filigree Emerald Green Glass Stones Brooch

This is an antique Czech Art Deco brass filigree brooch with emerald green glass stones. It dates back to the Art Deco period (1920's - 1930's). The piece is marked "Made in Czechoslovakia" and 712. This is a beautiful piece and in very good Antique condition. I could not determine what the 712 means. This is a lovely piece of Art Deco history and a well made brooch. It would make a great addition to any jewelry collection. It is from my private collection.
