This elegant two-toned knot ring is by the prestigious jewelry house Christofle, a French jeweler founded in Paris in 1830 who supplied many kings and emperors with their fine silverware, expanding to jewelry, and still in business today. 

The ring is stamped inside with the designer's hallmark and outside the shank with French makers' marks. In excellent condition. This ring can be sized, though it may interrupt the back design slightly, where the yellow and white gold portions meet. A stunning and timeless ring!
