This is a vintage brooch pin by Schreiner, featuring large green glass cabochons set in prongs. The pin is 2 inches long and is made of glass. It is a beautiful piece of fashion jewelry that is perfect for women who love retro styles. The brooch pin has a green color theme and is designed to showcase the beauty of art. It is not signed, but I was told that it is by Schreiner. If I am wrong, please let me know. Nevertheless, it is a gorgeous vintage piece.
