Necklace Victorian Mourning Jet Glass Bead 60" Bohemian

Antique beautiful black bead necklace - 1 single strand that measures 60" in length. Flapper length with no chipped beads. I believe they are Bohemian glass beads with a faceted style to them oblong in nature. Beads are on black fine textured cord hand knotted between each bead.  Condition is very good - Pre owned Antique. I did replace the clasp as the old one was non-functional.
