This ring is a great deco era styling, featuring a girl in 1920's head garb with shorter hair. The carving is nice, although the poor girl does have a bit of a nasal problem. I have examined this again and again and feel this is basically the original carving, and not later damage, although there is a slight mark on the bezel near this area.
The stone is a striped agate, all one piece. the yello gold mounting is stamped "10k" . The top of the ring measures about 19.5mm, about 3/4", from north to south. The cameo measures about 16mm x 12mm. It is a size 8 3/4.
