This architectural stepped gold and diamond ring by Cartier Paris presents a clever and sparkling commentary on artistry and illusion. From different viewpoints, this Retro ring is alternately a sculptured triple diamond band of escalating stepped levels, or a high bombé fan-form with vertical flutes, topped by an arch of diamonds set in platinum. Sly, elegant and artistic, it is a two-for-one jewel offering intriguing and utterly different perspectives.
