Unusual Large Antique Vulcanite Mourning Bangle Bracelet

Found this bracelet at a thrift store today. As an update I’m not entirely sure whether it’s made of Vulcanite or Gutta Percha but I’m leaning more towards Vulcanite. It’s a very unusual style and shape as well. One half has a more bulbous area while the other half has a more thinner less chunky area. It’s dark brown in color with slight visible yellow plumes in some areas. No carvings or other molded shapes just a thick chunky bangle design. The inner diameter is 2 3/4” inside. Weighs a hefty 93g.
