Odd locket, wooden backside and saint image

[Cushing]

Hi.
I purchased a rather odd locket in Poland and would need help identifying both age and definite origin. I am utterly confused because of the wooden backside. The stone on the cover is hematite. Any help would be very appreciated.

No clue but it’s a very cool piece and I’m part Polish.
