Victorian era, intricately carved coral ring in a dog head motif. Looks to have been set later in antiquity on a 14k gold band.
Approximately a size 6.5. 20mm by 15mm by 14.5mm thick. Some separation between band and ring face, indicating that this was likely converted to a ring in antiquity. However, ring is very sturdy. Can be seen in photos. Weight is 9.24 grams.
