Chopard Happy Diamonds Icons White Gold Pendant. Model reference: 79A611-1001. The Happy Diamonds by Chopard is an epitome of heart-shaped jewellery and the Happy Diamonds Icons line is a true confirmation of it. This very model is an example of a wonderful combination of fine 18K white gold presented in the form of a heart and the brand's hallmark, three mobile diamonds, placed within the pendant. The jewellery piece hangs down on a 42 cm length necklace and provides a marvellous play of the light captured within the stones' facets.
