Egyptian Pharaoh Copper Ring With Snakes

Old brass ring depicting Egyptian Pharaoh with two snakes and ruby eyes, one ruby missing. This copper ring is not marked, seems very old especially by the wear on the pharaoh’s face. I have never seen a ring designed like this, it’s basically two parts with the copper snakes body looping through and connecting the Pharaoh image to the main ring body. Any help identifying its age or who might of made it, would be great. Thanks for looking.
