The Sovereign Emerald Cut Three-Stone Lab Diamond Engagement Ring

$1,800

Click here to request a video. The Sovereign is a bold emerald cut three-stone engagement ring created for strong presence and clean geometry. The step-cut center diamond brings mirror-like flashes, while the side stones frame it with a sculptural, high-jewelry feel. It is dramatic without being overly ornate — a statement bridal ring with old-money confidence, architectural lines, and custom-made proportions. The emerald cut center stone gives the ring a crisp, elongated look with elegant finger coverage. The three-stone layout adds width and balance, making the ring feel substantial on the hand while keeping the design polished and intentional. This style is ideal for clients who prefer structured brilliance, clean lines, and a ring that feels more like a bespoke jewelry piece than a standard engagement ring. This ring is crafted to order. The center diamond size, metal, metal color, and US ring size can be customized before production. Center stones over 1 carat are typically selected as high-quality lab-grown diamonds with IGI certification, E color, and VS clarity by default, with upgraded grades available upon request. Side diamonds are selected to match the center stone visually and structurally, using D–E color and VS–VVS clarity standards when applicable. Common carat sizes are available through the product form, and other sizes can be quoted privately. Because this is made to order, the side-stone proportion can be selected to visually match the chosen center stone. No. This version is set as made to order. 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 solid gold 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.
