CHOPARD Happy Hearts 18-karat rose gold, onyx and diamond necklace

Chopard wants its 'Happy Hearts' jewelry to act as a reminder to live every day with joie de vivre. From the collection, this necklace is cast from 18-karat rose gold and strung with two heart-shaped pendants - one features a single floating diamond and the other is set with sleek black onyx that's surrounded by a row of glistening diamonds. The chain can be worn at three different lengths.
