CATENA — Italian for ‘chain’ — is the necklace expression of the continuous diamond line worn at the wrist as LUMINA ALBA RIVIÈRE. A single unbroken rivière of brilliant-cut lab-grown diamonds traces the neckline, each 2mm stone held in its own four-claw setting and lifted clear of the metal so light enters from every angle. The articulated line falls fluidly and sits close against the skin.
Available in solid 18K gold — white or yellow — in four lengths from 45.7cm (18") to 61cm (24"). Secured with a box clasp and safety catch. Made to order in your chosen metal and length.
