Seraphine Emerald-Cut Three-Stone Lab-Grown Diamond Engagement Ring

$3,420

Seraphine centers a 5.07ct E VS1 emerald-cut lab-grown diamond in a classic three-stone composition. Step-cut trapezoid side stones extend the center’s clean geometry across a Pt950 platinum setting. The long emerald facets create a crisp, mirror-like center, while the tapered step-cut side stones widen the composition without interrupting its symmetry. The platinum setting keeps the overall look cool-toned, architectural, and substantial on the hand. The center diamond is documented as 5.07ct, E color, VS1 clarity, with an IGI report, Excellent polish, Excellent symmetry, and no fluorescence. 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.
