18K yellow gold bracelet. Much more than a jewel, the Quatre bracelet is a jewelry sculpture, an ode to the light. The Radiant Edition line is the most visually graphic and flamboyant of all. Monochromatic in yellow, white or rose gold, it is a celebration of pure gold – a quintessential expression of Boucheron style. It is a bold statement of style and independence, a state of mind.
