14k Yellow Gold Earrings with Natural White Diamonds The Pillar Collection began with an ancient Roman gold ring dating somewhere between the 2nd and 5th century CE that we couldn't stop thinking about. Instead of recreating it, we borrowed the carved textures, the architecture, and the warmth of the gold and let them guide the collection from there. The Diamond Pillar Earrings let you decide just how much Pillar you want to wear. Wear one as a stud, two as a drop, or all three when you're in the mood for a little extra drama.
