Antique Gold Hard Carved Stone Green Agate Cameo Stick Pin of a Roman Soldier circa 1915.

Antique Carved Hard Stone Cameo Stick pin of a roman soldier. The metal does appear to be gold or gold plated, but the stamp on the pin is faded and I’m not sure what it said. Also on the side of the metal very lightly is the numbers 1682 or 1082 carved in the metal, I believe it is a green agate stone. Circa 1915-1925 well carved. The total measures is 2-1/2” long by 3/4” wide. Weight is 12.6 grams. Good condition.
