This is an ancient Roman intaglio, dating to the 2nd century A.D. It is nicely cut on a tiny carnelian gemstone, with an image of Mars (the god of War). This gem would have once been set, into a military gold or silver signet ring, used to seal and authenticate letters and dispatches. Today this ancient gem has survived down to us in good condition, suitable for remounting or to add to your collection.
