1 Ct Marquise (F/VS) Lab Grown Diamond Trellis Prong 14K White Gold Plain Cathedral Solitaire Engagement Ring
This magnificent 1Cttw lab-grown diamond engagement ring is a masterpiece of minimalist elegance, featuring a high-quality solitaire design set in 14K white gold. The focal point of the design is a brilliant 1-carat marquise-shaped center stone with an exceptional F color and VS clarity. The center diamond is held by a secure six-prong trellis setting, which gracefully intertwines to cradle the stone's unique silhouette. The elevated cathedral-style shank rises to meet the center head, adding a sophisticated architectural profile and a sense of grandeur to the ring. The band features a polished, plain gold finish, allowing the icy brilliance of the marquise diamond to remain the undisputed star. This ring combines the traditional navette shape with modern structural detail, making it an extraordinary and timeless choice for a proposal.
