This is a lovely ruby and crysolite cluster, ca 1845. I love everything about this ring, including the wonderful split shank. There has, most likely, been a hair pocket in the back of this ring. The empty pocket is there, but there is no glass. The gold is unmarked but tested 14 carat gold. It is a size 8, but it could be resized. The decorated top of the ring measures 1/2 inch North to South, and about the same, East to West.
