Chopard Happy Diamonds Icons Rose Gold Diamond Pendant. Model reference: 81A017-5001. The elegance and variety of forms are the things that make Chopard's jewellery so adorable and magnetizing. The Happy Diamonds Icons portrays these principles to the fullest. The very model is a gorgeous necklace made of fine 18K rose gold hanging down on a delicate chain. The pendant itself is a round-shaped frame that houses the brand's hallmark, a mobile diamond. The precious stone dances smoothly in the light within a pair of sapphire crystals providing marvellous glimmering.
