Classic 4-Prong Oval Lab Grown Diamond Solitaire Ring | Engagement Ring

$3,720

Product 5127 is built around a truly impressive oval lab-grown diamond. At 5.01 carats , the center stone offers substantial finger coverage and a luminous face-up appearance, while its elongated curves create an elegant, flattering silhouette on the hand. There is no unnecessary decoration competing with the diamond. Every line of the ring is designed to support its scale, brilliance, and natural beauty. The polished solitaire band keeps the overall appearance clean and timeless. From the front, the slender metal profile allows the oval diamond to remain the sole focal point. From the side, the setting reveals a more sculptural structure that supports the stone without making the ring feel visually heavy. The result is classic, but never ordinary. The elevated gallery uses sweeping metal supports beneath the diamond to create an open and airy profile. This structure: The setting feels refined from above and architectural from the side. Each stone is a laboratory-grown diamond, chemically, physically and optically identical to a mined diamond, selected for brightness and well-matched colour. The ring is handcrafted to order in precious metal by our partner atelier, then hand-polished and inspected before it leaves the workshop. Metal colour, size and stone details can be tailored on request before production. Every Riakoob piece arrives with a certificate of authenticity, insured delivery, and our 12-month value promise.
