Yes definitely pressure flaking all over the piece referred to as debris.
As far as the material a location will definitely help I'm guessing the Northeast
Hey there METAL, you are in the mid Atlantic area aren't you? We find artifacts here occasionally that look to be made of a similar semi translucent material, to the piece in question. We generically call it "chalcedony", and sure wish we were able to find more of it. Pretty stuff whatever it's name and source.
