14k Yellow Gold Pendant with a Natural or Lab-Grown Diamond After seeing how much we loved the silhouette of the Dune Ring, we knew it needed a companion. The shape quickly became a favorite around the studio, and it wasn't long before we started imagining it as a pendant. The Dune Pendant brings that same pear-shaped silhouette to a necklace, pairing a brilliant diamond with softly curved gold. A natural extension of one of our favorite designs.
