Three Stone Round Diamond Engagement Ring LR4086The LR4086 is an 18k white gold three stone engagement mounting, with two round brilliant side stones in G H, VS quality and a Simon set center that minimizes metalwork and keeps the diamond open. Additional round brilliants continue down the shank, giving the ring a consistency that carries through from the crown to the band. The three stone format has always told a story & this one tells it well.
