Gilt bronze, about 5/8” (0.65”) height plus the ring. Large domed form, fluted and the back recessed. A form about which there is some uncertainty. Romans were very dependent on the sea and used sea motifs, real and mythical extensively in their art and decoration. Sea shell are depicted in mosaics and wall paintings. However, several variant sources describe these as worn specifically by prostitutes. As prostitution was openly practiced, that may be the case. Professionally refurbished with the 24karat gold surface restored on an 18” gilt Sterling silver neck chain for contemporary wear. Gift boxed with certification of authenticity.
