Dating from the 1870s, this English Renaissance Revival gold plaque necklace features a large oval-cut amethyst, basse-taille enamel, and natural seed pearls. The oval-cut amethyst is framed by delicately shaded enamel shells, and joins a necklace of enamel rosettes alternating with beaded infinity-form links, accented by natural seed pearls and old mine-cut diamonds. Sitting lightly above the collar bone, this elegant and vividly-colored necklace is a graceful ornament to highlight and elongate the neck.
