This very rare Art Deco necklace is most likely Czech. Comprised of disc shaped beads in both green and black with gold plated filigree caps and separated by small glass beads. The old style spring ring clasp is gold plated and another clue to it's age and authenticity. When held under a black light, the green beads glow, due to the uranium oxide added to the glass in its molten state. This can be seen in the pictures.
This stunning vivid fluorescent greenish-yellow glass was invented in Prague by Josef Riedel in 1830's and he called it 'Annagrun', after his wife Anna.
