A wonderful art deco era Fishel Nessler pin. I am not sure if this is a hat or collar pin. Perhaps it could be used either way! Set in pot metal, each end has a large glass amber colored cabochon with rhinestone accents. It is NOT bakelite as it did not test positive with Simichrome cream.
One piece screws into the other and holds tight. It is in excellent condition, some slight wear and the rhinestones have "grayed". All age appropriate and to be expected for an 80 year old item.
It is signed F.N. CO and measures 4 x 7/8 inches.
