Van Cleef & Arpels unveils a jewelry collection with a rounded, graphic design: Bouton d’or ™ collection - Diamonds, gold, mother-of-pearl and hard stones come together in bold creations. The pink gold magnifies the delicate overtones of mother-of-pearl and the warm hue of carnelian, a symbol of life. With their glittering centers, the motifs spread out across different levels, in triple rows or joyful circles.
