Vintage 14 Karat yellow gold (tested by acid) mounting is set with a finely carved hard stone black and white onyx cameo. The onyx cameo features a detailed carving of a lady with her flowing hair pulled back and wearing an earring. The cameo measures 15mm by 11 mm (approximately 9/16" by 7/16"). The unique mounting features an organic branch motif which frames the prong set cameo. The top of the ring measures 21.5 mm (approximately 7/8") in length. There is a very faint (difficult to see)14K mark on the inside if the shank. The ring is currently a size 5 3/4 and can be easily resized.
