Lovely Antique 18K Gold Hardstone Agate Cameo Ring. It is a nice large size, measuring 7/8" in length. It weighs 5.9g and is a Size 8. Hallmarked w/impressed K, tests as 18K. Good condition, no cracks. The edges of the very high set agate are a little worn/rough in spots. Quite minor, it doesn't bother me and I am quite fussy.
