Marquise Lab-Grown Diamond Engagement Ring in 14K White Gold (IGI Certified)
This marquise lab-grown diamond engagement ring lifts an IGI-certified marquise diamond — D color, VVS clarity, ~1.7ct at 6×12mm — in an open basket setting with rounded prongs, above a petite 1.7mm band accented with lab-grown diamonds, all in solid white gold. The elongated marquise stretches the finger and throws maximum sparkle from an airy, light-flooded mount. Choose your karat and metal below.
The diamond
The marquise center is a genuine lab-grown diamond — chemically, physically, and optically identical to a mined diamond (same carbon structure, same 10 Mohs hardness, same brilliance), grown in a lab and clearly disclosed. It's D color (the top, completely colorless grade) and VVS clarity, and its elongated marquise outline maximizes surface spread — it wears larger than its carat weight and elongates the finger beautifully. Every ring ships with an IGI certificate and unique serial number. Learn more in our complete guide to lab-grown diamonds, how lab-grown diamonds are made, and IGI vs GIA certification.
The open basket & petite band
Rounded prongs cradle the marquise in an open basket that lets light flood the stone from every angle for maximum brilliance, while the petite 1.7mm band — accented with smaller lab-grown diamonds — keeps the profile refined and lets the center take center stage. It's a delicate, modern silhouette with real presence on the hand. A matching wedding band can be custom made to order — message us.

Choose your metal & karat
Every version is solid white metal throughout — never plated or filled. Pick the karat that fits your priorities using the Metal selector; each is priced accordingly. Not sure which to choose? Our 10K vs 14K vs 18K gold karat comparison guide breaks down the trade-offs.
10K White Gold
41.7% gold. The most budget-friendly and hardest-wearing option — a great everyday choice.
14K White Gold
58.5% gold. The most popular bridal choice — the sweet spot of durability, warmth, and value.
18K White Gold
75% gold. A richer, more luxurious feel with the highest gold content of the golds.
Platinum
Naturally white, exceptionally dense, and hypoallergenic — the premium heirloom metal, never needs re-plating.
Why solid white metal
Every option here is solid — the metal itself, not plating or vermeil over a base metal. The cool white keeps the marquise reading bright and icy while the accent diamonds sparkle. The color is permanent: it won't wear off and won't turn your skin green. White gold in 10K, 14K, or 18K takes a rhodium finish for a bright mirror-white; platinum is naturally white and develops a soft patina over time. Yellow or rose gold is also available on request.

Sizing & care
Diamond is 10 Mohs — the hardest gemstone, effortless for daily wear (a marquise's fine points sit protected by the prongs). Clean with warm soapy water and a soft brush to keep the accents bright. Please reference our sizing guide before ordering. An optional written appraisal can be added from the drop-down menu (non-refundable once completed).
Marquise lab-grown diamond ring FAQs
Is the diamond real?
Yes — a genuine lab-grown diamond, chemically and optically identical to a mined diamond, with the same 10 Mohs hardness and brilliance. Real diamond with a lab origin, clearly disclosed — not moissanite or CZ.
Why choose a marquise cut?
The elongated marquise has the largest surface area per carat of any shape, so it wears larger than its weight and visually lengthens the finger. Its pointed ends and 1.7ct spread give it dramatic presence in an elegant, slender profile.
What's the difference between 10K, 14K, 18K, and platinum?
The karat number is how much of the metal is pure gold: 10K is 41.7%, 14K is 58.5%, and 18K is 75%. Lower karats are harder and more affordable; higher karats feel more luxurious. Platinum is a naturally white precious metal — denser, hypoallergenic, and never needs re-plating. All are solid throughout. See our karat comparison guide for details.
Does the open basket keep the diamond secure?
Yes. The rounded prongs hold the marquise firmly while the open basket lets light in from below for extra brilliance. The delicate points are protected within the prong tips — a classic, secure way to set a marquise.
Is there a matching wedding band?
Yes — a matching band can be custom made to order and is sold separately. Message us and we'll design it to nest with this ring.
Is this real solid white gold?
Yes. Every white-gold option is solid 10K, 14K, or 18K throughout — the metal itself, not plating or vermeil. The color is permanent, won't wear off, and won't turn skin green. A platinum option is also available.
