Found the metal one and got the carnelian one in an old collection that I purchased. kind of curious if anyone can Id them.

Hey neat, I have a ring that has been handed down through the years in the family that has the same Roman figurehead only difference is that mine is on a black stone, I was told it came from a larger collection of similar pieces that were inserts from a necklace, and broken up and seperated for different jewellery earlier on this century. Curious what you find out as well, Chris
