Cameo ring - A plain hoop mounted by a table setting, into which was affixed a carved cameo (in profile). This ring style is exceedingly ancient and was more commonly worn by men than by women. Most commonly, the cameos depicted pagan gods, Christian saints and even self-portraits. Multi-coloured stone and often marble or porphyry was most desirable, as it produced a striped, layered or three-dimensional effect.
