This is a Coral Cameo Stick Pin set in 14K Gold. Date this One circa first 1/4 of the 20th Century. The Top Measures 1/2" Wide X 5/8" Long and is Nicely Bezeled; overall the Pin measures 2 3/8". Did not find a gold mark though has been tested and is Guaranteed 14K. Can't emphasize enough the Quality Work to the Carving. Excellent Addition to the Collection.
