Necklace designed by Elsa Peretti for Tiffany. The piece could be termed vintage as the style is no longer available, but now comes in an "updated" look. When Kate bought this necklace, the collection was Cabochon by the Yard, but is now Color by the Yard. 18k gold with a lapis lazuli cabochon and two round brilliant diamonds. Current retail: $1,150.
