Vivienne Oval & Trillion Three-Stone Lab Diamond Ring

$720

Vivienne is a modern interpretation of the classic three-stone diamond ring. At the center, an elongated oval lab-grown diamond creates the primary focal point. On either side, two trillion-cut lab-grown diamonds angle outward, extending the brilliance across the finger and creating a beautifully balanced transition into the band. Rather than relying on halos or additional pavé, Vivienne builds its presence entirely through the proportions and relationship of three statement diamonds. The result is substantial without feeling overly decorated — timeless, architectural, and effortlessly luxurious. The oval center diamond gives Vivienne its soft, elongated character. Its rounded outline brings elegance to the composition, while the elongated proportions create generous face-up coverage and visually lengthen the finger. The setting keeps the oval diamond highly exposed, allowing its brilliance and outline to remain the focus from every angle. What gives Vivienne its distinctive personality are the two trillion-cut side diamonds . Positioned with their tapered points flowing toward the band, the triangular stones create a natural visual transition from the larger oval center to the polished shank. Their sharp geometry contrasts beautifully with the soft curves of the oval. Soft at the center. Architectural at the sides. This contrast gives Vivienne a more contemporary character than a traditional three-stone ring with round or oval side stones. From the front, the three diamonds sit closely together to create a broad, almost continuous composition across the finger. The trillion side stones extend the visual width of the center diamond, creating impressive finger coverage without the need for a surrounding halo. This makes Vivienne especially suited to someone who wants a substantial diamond look while keeping the design clean. There is very little visual distraction — the diamonds themselves create the scale. Turn Vivienne to the side and the architecture becomes visible. The center and side stones are supported by an open gallery that allows their profiles and lower facets to remain visible rather than hiding them behind a heavy metal structure. This gives the ring a lighter, more dimensional appearance and allows the three stones to remain visually distinct. The polished band then narrows the composition back toward the finger for a clean, balanced finish. Vivienne deliberately avoids additional decorative elements. There is: No halo. No pavé band. No elaborate engraving. Instead, the design relies on three beautifully proportioned diamonds and precise setting work. This restraint gives the ring a timeless quality and makes the substantial center-and-side-stone combination feel sophisticated rather than excessive. The three-stone ring has long been associated with past, present, and future . Vivienne gives that symbolism a more modern visual language: one prominent oval center flanked by two sharply defined trillion diamonds. It makes the design particularly meaningful as an: Product Number: 5526 Product Name: Vivienne Jewelry Type: Three-Stone Lab-Grown Diamond Ring Center Stone: Oval-Cut Lab-Grown Diamond Side Stones: Two Trillion-Cut Lab-Grown Diamonds Setting: Prong Setting Design: Three-Stone / Trilogy Band Style: Polished Plain Band Gallery: Open-Profile Setting Customization: Available Production: Made to Order / Selected Specifications as Available Vivienne can be customized around your preferred center diamond.

Vivienne is ideal for: Certification depends on the selected center diamond specification. For eligible center stones, an independent diamond grading report can be provided. Each Vivienne ring is created around the proportions of the selected center stone. Because lab-grown diamonds are individually cut, exact dimensions, ratios, side-stone proportions, and total carat weight may vary slightly between rings. This allows the side diamonds and setting to be proportioned specifically to the selected center stone rather than forcing every diamond into one fixed mounting. Clean with warm water, mild soap, and a soft jewelry brush. Because Vivienne features three prominent prong-set diamonds, avoid strong impact and pressure against the stones. Periodic professional inspection of the prongs is recommended for long-term wear. 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.
