Marquise Cut Lab-Grown Diamond Engagement Ring Set in 14K Solid Yellow Gold (IGI Certified)
This marquise lab diamond ring set in yellow gold centers an IGI-certified lab-grown marquise cut diamond — D color, VVS clarity, ~1.1ct — on a chevron band with lab-grown diamond accents and a coordinating band, all in warm solid yellow gold. The elongated marquise silhouette in rich gold: vintage-royal glamour with modern, sustainable brilliance.
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. To learn more, see our complete guide to lab-grown diamonds, how lab-grown diamonds are made, and IGI vs GIA certification.
The marquise cut & set
Engagement Ring
Marquise lab diamond center (5×10mm, ~1.1ct, D/VVS) on a chevron band with lab diamond accents. Solid yellow gold.
Matching Band
Coordinating band designed to nest against the engagement ring. Matching solid yellow gold.
The marquise's 2:1 elongated shape maximizes visual size per carat and lengthens the finger like no other cut — and in yellow gold it carries the regal, vintage character the cut was born with. See our marquise engagement ring guide. Sold as a two-piece set; each ring can also be worn on its own. Explore more lab-grown diamond engagement rings and coordinating wedding ring sets.
Choose your karat
This set is solid yellow gold — the metal itself, not plating or vermeil over a base metal. Pick the karat that fits your budget and durability preference. All three are genuine solid gold; the higher the karat, the richer and warmer the gold tone. See our 10K vs 14K vs 18K karat comparison guide and our yellow vs white vs rose gold guide for the full breakdown.
The warm gold gives the colorless diamond a rich, heirloom-classic contrast. Prefer a different color? This design is also available in white or rose gold on request. Whichever karat you choose, the color is permanent — it won't wear off and won't turn your skin green.

Sizing & care
Diamond is 10 Mohs — the hardest gemstone, effortless for daily wear (the marquise's points sit protected in the setting). Clean with warm soapy water and a soft brush. Both rings should be ordered in the same size; 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 diamond ring set 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 maximizes visual size per carat and lengthens the finger more than any other shape — a 1.1ct marquise reads noticeably larger than a round of the same weight.
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.
Which karat should I choose?
All three are genuine solid yellow gold. 10K is the hardest and most affordable with a lighter tone; 14K is our most popular for its balance of warm color, durability, and value; 18K has the highest gold content and the richest, warmest tone. See our karat comparison guide for details.
Is this a set or a single ring?
It's a two-piece set — the marquise diamond engagement ring plus a coordinating band. Each can also be worn alone.
Is this real solid yellow gold?
Yes. The set is solid yellow gold throughout — the metal itself, not plating or vermeil. The color is permanent, won't wear off, and won't turn skin green.
