14k Yellow Gold Ring with Natural Emerald and 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 Emerald Pillar Wrap Ring was our chance to bring color into the collection. Something about the pear shaped emerald and carved gold felt like they belonged together from the start.
