Marquise Lab-Grown Diamond Engagement Ring in 14K White Gold (IGI Certified)
This marquise diamond solitaire engagement ring centers an IGI-certified lab-grown marquise diamond — D color, VVS clarity, ~1.7ct at 6×12mm — set in an airy open basket with rounded prongs on a petite high-polish band, in solid white gold. Elegant, elongated, and timeless: a refined solitaire that lets light flood the stone from every angle. 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 every ring ships with an IGI certificate and unique serial number. The pointed marquise silhouette maximizes surface area, so the ~1.7ct stone reads large and dramatically elongates the finger. Learn more in our complete guide to lab-grown diamonds, how lab-grown diamonds are made, and IGI vs GIA certification.
The open basket setting
An airy open basket with rounded prongs cradles the marquise, letting light enter the stone from every side to maximize brilliance. The petite 1.7mm high-polish band keeps the silhouette sleek and minimalist so all eyes stay on the center stone. 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 doesn't compete with the diamond's white light return, letting the D-color brilliance read at maximum. 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.

Marquise diamond solitaire 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, pointed marquise has more surface area than most cuts of the same weight, so it looks larger and dramatically lengthens the finger — an elegant, statement-making silhouette.
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.
What do D color, VVS, and IGI certified mean?
D is the highest color grade — completely colorless. VVS means inclusions are virtually invisible under 10× magnification. IGI is one of the leading diamond grading labs; your certificate documents the stone's exact weight and grades with a unique serial number.
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 solitaire.
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.
