Silhouette Emerald Diamond Engagement Ring LVS945Uneek's LVS945 in platinum carries a fancy pink emerald cut diamond at center, framed by a rectangular halo of 84 pav round brilliants and a double shank that tapers and curves along the finger in the Silhouette Collection's signature form. The total diamond weight reaches 6. 14 carats, though the pink center is what set this ring apart. An engagement ring that arrives already feeling like an heirloom.
