Clover Lumière bracelet in 18 carat Black Gold, with Black resin pearls. This gigi CLOZEAU Trèfle Lumière diamond bracelet combines the Maison’s signature black rhodium-plated 18 carat gold chain and black resin with an 18 carat rose gold motif. Black on Black, a new signature. Deep black, a black chain: the signature chain in black rhodium-plated 18 carat gold and black resin reveals an 18 carat rose gold motif. The contrast between intense black gold and soft rose gold creates a magnetic, timeless look to wear alone or mix with gigi colours. Black rhodium-plated 18 carat gold reveals a deep, dark shade created from white gold. Over time, the rhodium plating may naturally evolve and develop a patina. This natural evolution is not considered a defect.
