Two Tone Twist Diamond Engagement Ring LR2637Simon G's LR2637 pairs a three stone round brilliant layout with a two tone braided band in 18k yellow and white gold, finished with side stones totaling approximately 0. 24 carats in G H color and VS2 clarity. The mixed metal twist gives the ring a sculptural quality that sets it apart from a standard three stone silhouette. A natural choice for someone who layers their jewelry and wants their engagement ring to work within that.
