Vintage camphor glass, filagree necklace with the Theosophical Seal

Beautiful vintage necklace, the camphor glass and filagree are delicate. The star in the middle, I have been told , is the Seal for the Theosophical Society. Necklace is still in its original box. Camphor glass became popular in jewelry in the 1920’s, this necklace with the filagree has an art deco look. Fabulous piece of vintage jewelry. Offers are appreciated.
