This cameo is cut from Lava and is set in a silver base metal that seems to be about 800 silver but there is no markings that i can find. It is the profile of an oldeer, wiser gentleman perhaps one of the great philosopers? Mabe a king? or a Pope? do you know? It is in top shape and the pin is all in tack and working. Measures about 1 inch and a quarter high and one inch wide. Great collectors piece!
