Boucheron - Quatre Classique Large 18-Karat Yellow, White And Rose Gold, Pvd And Diamond Ring - 52

Each contrasting texture and precious metal in Boucheron's 'Quatre' collection represents an iconic code of the house - the 'Grosgrain' is a tribute to the founder's couturier grandparents, while the angular 'Clou de Paris' mimics the city's cobblestone streets. This large version of the 'Classique' ring is stacked with 18-karat yellow, white and rose gold bands and a striking brown PVD one. It's inlaid with diamonds totaling 0.49-carats as a final dazzling flourish.
