Composed of old mine and rose-cut diamonds, this rivire necklace is mounted in enameled 18K gold. Each old-mine cut diamond, graduating in size from approximately 0.50 carat to 0.15 carat, is box-set, with a champlev black enamel surround, and highlighted by rose-cut diamond accents. With its contrast of scintillating, fiery cushion-shaped old mine diamonds against rectilinear matte black enamel surrounds, this unusual take on the traditional rivire form sits lightly on the neck and makes for a youthful and versatile jewel.
