Anissa Kermiche's engineering background helped her master the 3D printing technique she uses to create her fine jewelry - she prefers that process over sawing, filing and soldering. Handmade from 14-karat gold, this 'Belle de Nuit' necklace has an organic-shaped pendant that's set with an onyx framed by sparkling diamonds. Adjust to the chain four different lengths to suit your neckline.
