Condition: area touch up and restoration to the black enamel. Due to age-related oxidation and tarnish, the diamond foils are not the same degree of brightness across 23 stones; some diamonds appear darker than others. A tiny hard-to-spot nibble to the edge of the cover crystal (shallow, does not penetrate to the portrait level). Overall there’s age-related light surface wear and patina throughout. The shank is not a perfect circle.
