EXCLUSIVE AT NET-A-PORTER.COM. Loren Stewart founders and friends Rachel Loren, Satya Stewart and Annah Stewart-Zafrani used to melt down vintage jewelry to make their own pieces, which was how they came to launch their brand. This handmade 14-karat gold earring has a square 0.67-carat white topaz stud and is dotted with two pearls along the length of the fine chain. It almost reaches your collarbone, so we like it with one-shoulder tops.
