Boucheron 18ct white-gold ring. 100% 18ct white gold; plating 100% PVD. Slips on. Single band, engraved logo, polished finish. We recommend you to opt for 1 size larger than your usual size. Gently scrub the pieces with a very soft brush dipped into soapy water, then carefully rinse them and delicately dry them with a soft, non-lint cloth. You will collect your order at the Boucheron boutique in The Wonder Room.
