Antique Cut Steel Stick Pin
This pin's intriguing design includes engraving, enamel, and a ring of sparkling, individually faceted and set steel pins. Back of pin is mother-of-pearl which makes me think it may have started life as a button. Since there are offers no hallmarks I can only call it yellow metal.
Head is 18mm wide. Pin is 65mm long
