These vintage glass sew on rose montees are a lush ruby red glass and measure 23mm long x 7mm wide. They are a navette (marquise) shape prong set in a silver color metal bezel. They were made in Czechoslovakia and although originally made as sew on embellishments they are great in jewelry. I have threaded some headpins through the channels on the back to show their orientation. You will receive 12 pieces.
