This 18K yellow gold Yvonne Léon mixed chain diamond necklace is crafted in France with contrasting sides. One half features small links, while the other has long links, with both sides meeting in the middle at a round cut diamond weighing 0.1 carats. It secures with a spring clasp. We can easily while away the time on solitaire. And by that, we mean admiring Yvonne Léon's jewels.
