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

Choose your metal & karat
This set is made in solid white gold or platinum — the metal itself, not plating or vermeil over a base metal. Use the drop-down to choose what suits you:
10K White Gold
The most affordable and the hardest-wearing gold option — a great everyday choice with a bright white finish.
14K White Gold
Our most popular pick: the classic balance of durability, cool white color, and value.
18K White Gold
The highest gold content among our gold options — a richer, more luxurious white with heirloom feel.
Platinum
Naturally white, hypoallergenic, and the most durable and dense of all — a premium, lifelong choice that never needs re-plating.
Higher karat means more pure gold; lower karat is harder and more budget-friendly; platinum is the densest and most enduring. Not sure which is right? Our 10K vs 14K vs 18K gold comparison guide walks through durability, color, and price. Cool white metal lets the D-color diamond's brilliance read at maximum. Prefer yellow or rose gold? Just leave a note at checkout.
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. Our marquise engagement ring guide covers the shape, our complete guide to lab-grown diamonds and how lab-grown diamonds are made explain the science, and our IGI vs GIA certification guide covers the grading.

Marquise diamond ring set FAQs
Which metal and karat should I choose?
All options are solid white gold or platinum — never plated. 10K is the hardest and most affordable gold, 14K is the most popular all-round choice, 18K has the highest gold content, and platinum is the densest, naturally white, and hypoallergenic. Prefer yellow or rose gold? Just leave a note at checkout. See our karat comparison guide for details.
Is a lab-grown diamond a real diamond?
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. Our complete guide to lab-grown diamonds explains more.
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. See our IGI vs GIA 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, and both are made in the metal and karat you choose.
Is this real solid white gold?
Yes. The set is solid white gold in your chosen karat (or solid platinum) — the metal itself, not plating or vermeil. The color is permanent, won't wear off, and won't turn skin green.
