This is beautiful antique Edwardian cameo made of pink (conch) shell. It is set in 10K gold and it is highlighted with black enamel and surrounded by tiny seed pearls. It is made to be worn as either a brooch or a pendant. The pin catch is the older style of safety catch and it is marked 10K. The bail is made to flip up or down as needed and it also swivels so as to accommodate the chain without requiring an additional loop. The cameo is very nicely carved and the delicate setting enhances the beautiful pink of the shell.
It measures about 1 1/4 inches by 1 inch and it is in very good condition. As can be seen in the photographs, the gold wire surrounding the pearls is slightly flattened near the bottom.
