Vintage German glass, double sided window beads in black. The glass has been plated with 24k gold and topped with gold plated spacer beads. Hung on classic 14k gold fill French ear wires. These opaque glass beads are vintage and were only made from the 1920's through the 1960's in West Germany. The original factory was destroyed in WWII. The maker of these beads invented a method for electroplating 24k gold to glass, first by plating the glass with platinum and then plating the gold over it. They are rare and no longer in production thus making them even more special as they dangle from your lobes.
