Marquise Lab-Grown Diamond Butterfly Engagement Ring in 14K White Gold (IGI Certified)

A vintage-souled marquise diamond engagement ring: an IGI-certified lab-grown diamond framed by lotus-petal prongs, butterfly silhouettes in the antique-style openwork gallery, crowned diamond points above and below the stone, and a twisted vine shank — all in Solid White Gold · 10K / 14K / 18K · Platinum.

An Art Nouveau Heirloom, Made New

The marquise sits north-south, and the design extends its lines: a crowned diamond point rises above the tip, a mirrored point descends below, and the whole face reads as a single elongated compass star. The openwork gallery carries the airy, pierced character of antique Art Nouveau jewelry — lotus petals cradling the center, butterfly wings unfolding at the shoulders, a shank twisting like a vine. In white gold with a colorless diamond, it looks like something inherited from a very stylish great-grandmother — except the stone is graded, certified, and brand new.

The Lab-Grown Diamond: D Color, VVS, IGI Certified

The center is a genuine lab-grown diamond — chemically, physically, and optically identical to a mined diamond, simply created under lab conditions. At D color it is completely colorless, and at VVS clarity any inclusions are invisible to the naked eye. The round accents are lab-grown diamonds as well, so the entire ring carries matching diamond brilliance.

Every ring ships with its certificate from IGI, the International Gemological Institute, independently documenting the diamond's cut, color, clarity, and exact carat weight. If you're new to these stones, our complete guide to lab-grown diamonds walks through how they're grown, graded, and certified.

Why the Marquise Cut

The marquise has the largest face-up spread of any diamond cut per carat — its long, pointed silhouette stretches across the finger, making the stone look remarkably generous while elongating the hand. Beloved in antique and vintage jewelry, it's the natural centerpiece for an Art Nouveau-inspired design.

Choose your metal: 10K, 14K, 18K white gold, or platinum

Every ring is cast to order in your choice of solid white gold or platinum, each finished with bright rhodium for the mirror-silver luster white gold is loved for. 10K is the most durable and the most affordable. 14K is the classic balance of durability and gold content — our default and the most popular choice. 18K carries the highest gold content for a richer, more luxurious feel. Platinum is our premium option: naturally white, denser and heavier in the hand, hypoallergenic, and it never needs re-plating. Whichever you choose, the color is permanent — it will never fade and will never turn your skin green. See our 10K vs 14K vs 18K gold karat comparison guide for the full breakdown, and note that yellow and rose gold are available on request. The piece belongs to our lab-grown diamond engagement rings and solid gold engagement rings collections, and sits among our wider range of women's engagement rings.

Care & Craftsmanship

Each ring is made to order over 2–6 weeks — cast, set, and finished for your order specifically. Diamond and gold ask very little: warm water, mild soap, and a soft brush restore full brilliance. Store the ring in its velvet box when not worn, and remove it before heavy lifting or abrasive work.
