Beatific Mother of Pearl Pin Brooch in a Brasstone Setting

The details of this brooch are simple stunning. I believe it to have been a vintage import - guessing Hong Kong / Japan/ Philippines. Despite many hours of research I could not find another. If I had to estimate would deem this to be circa 1960’s to 70’s. I think I’ve underestimated price but it is what it is. I would describe this as very rare but not an expert.
