Platinum is one of the most durable and prestigious precious metals used in fine jewelry, prized for its natural white luster that will not fade or tarnish over time. Its density and strength make it an ideal choice for securing diamonds securely. The princess cut is the most popular fancy shape for diamond engagement and fashion rings, prized for its modern square silhouette and exceptional brilliance. This ring is sized 7 and comes with diamond certification documentation standard for Costco fine jewelry purchases.
