Victorian Era Black Enamel Gold Linked Ring

Victorian era chain link ring. Fantastic black enamel detail gives a sense of shadows. The ring is made in 15k yellow gold. England. Circa 1880. 

The ring has been loved and worn. There is some enamel loss, and there were once additional engraved details, but they have been worn smooth with time. These slight imperfections are visible in the photos. 

Size 6.75, not sizable.
