The Lucent is designed around light: an oval lab-grown diamond sits in an elevated cathedral setting, with a hidden halo tucked beneath the center stone for a quiet flash of brilliance from the side view. Its pavé band adds delicate sparkle without overwhelming the oval silhouette, creating a refined engagement ring that feels graceful, bright, and timeless. The elongated oval shape gives elegant finger coverage and a softly lengthening effect on the hand. The cathedral shoulders lift the center stone with balanced support, while the hidden halo adds depth and glow when the ring moves. This design is made for someone who loves a classic bridal profile with a little secret detail — polished from the top, romantic from the side, and luminous from every angle. 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 and pavé diamonds are selected to complement the center stone, with D–E color and VS–VVS clarity standards when applicable. Common website options are available through the product form, and other carat sizes can be quoted privately. It can be crafted in white gold, yellow gold, or rose gold, with 14K, 18K, and platinum options available when selected. No. 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.
