Designed by Paloma Picasso, this Tiffany & Co. "Circles" necklace is composed of 18K gold. The necklace is designed as an endless chain of circular alternating hammered and textured links of varying sizes and widths. Designed to slip over the head, this long and lovely necklace is casual, elegant and lightweight, cleverly harnessing the unique properties of gold to create subtle gleams and flashing highlight effects.
