NOH oriental mask brooch with filigree details vintage 50s For Sale

This is over all great condition with some tone wear but nothing major. This seems to be a rare piece by Florenza or Bohemia but it’s unsigned so I can’t confirm the maker. I believe the face is hand carved bone but no way to confirm. This measures nearly 5 inches including the necklace he wears. This is a very heavy piece for its size. Can be worn as a brooch or a pendnant.
