C. 100-300 AD. Roman. Gold ring comprising circular hoop and round bezel with a carnelian setting. The setting bears an engraved double bust of Janus, with both faces sporting thick curling hair, full beards and fierce facial expressions. In the Roman pantheon, Janus was the god of beginnings, gates, transitions, time, duality, doorways passages, frames, and endings. His two faces symbolise his ability to look both to the future and to the past. In order to confirm its authenticity, this piece has undergone X-Ray Fluorescence analysis by an independent Belgian Laboratory. The samples collected show the chemical composition to reflect the typical metal contents of the described period, whilst also showing no modern trace elements in the patina. Excellent condition.
