This early Victorian cameo is referred to as lava jewelry which became extremely popular for tourists visiting the buried cities of Pompeii, Herculaneum, etc. as the result of the volcanic eruption of Mt. Vesuvius. Lava cameos were generally easier to carve due to the softness of the material. As a result, they are often damaged. This cameo of a high relief portrait of an 18th century woman is in excellent condition. The cameo brooch rests on its original solid silver frame and pin with a simple clasp.
