The ouroboros, a snake in the form of a circle holding its tail in its mouth, in an ancient symbol of eternity. This motif has been used as a symbol of the infinite in jewelry for centuries upon centuries. The Victorian update to the motif paired two snakes together entwined in various knots or interlocking shapes to symbolize the eternal love between two people. This incredible twin snake ring dates to the mid 19th century. The snakes, encrusted with emeralds and rubies, link together to form an infinity knot at the face, their tails curl together to form an endless loop along the shank. No hallmarks, possibly Anglo-Indian in origin.
