This is an ancient Roman iron intaglio ring, dating to the 1st - 3rd century A.D. It is set with its original Nicolo glass gemstone, molded with an image of what appears to be a bird, dove or eagle.
This ring is in excavated condition, heavily corroded, but intact. A rare survivor and collectible example of an ancient Roman ring in iron (the metal par excellence of the true Roman patriot!)
