a Fine 19th century Lava Cameo Brooch, showing Athena / Minerva or a Soldier. of exceptional quality carving and good side. the fitting is a yellow metal, but i believe pinchbeck or similar.
approx 4.5 cm tall
in great condition some rubbing to the mount, some natural faults to the lava including a line down the face i dont think this is a crack as it looks.
