Vintage black cameo brooch

This large and possibly black jet Cameo brooch is from my mother in law’s collection. This pin feels like glass and I am only guessing that it is black jet based on my mother in laws age. It does appear that she may have done repair work to the pin at the backside as that says Japan. Gorgeous Victorian style and would be an amazing piece to add to your jewelry wardrobe.
