18k Gold Cameo Ring 9-9.25 Man Or God In Helmet

18k Gold Cameo Ring Size 9-9.25 Man Or God In Helmet The cameo is carved but I am not sure of material. The shank is stamped 18k. I have left all cleaning to the buyer. There are places where there is patina or buildup and some discoloration probably from the solder that was used long ago. Areas around the bezel have little irregularities in the gold where it isn’t completely smooth (see photos). Measures between a 9 and 9.25 as shown in photo. Weighs 6.3g. Ring box pictured not included.
