Marquise Cut Lab-Grown Diamond Engagement Rings

The marquise cut is a diamond shape with presence. Its elongated body and two pointed ends create a silhouette that stretches across the finger with a commanding sense of scale, making it one of the most visually striking shapes available. Originally commissioned by King Louis XV of France to mirror the smile of the Marquise de Pompadour, it is a shape that has carried a sense of occasion ever since.

At The Jewel Concierge, every marquise cut lab grown diamond engagement ring is crafted to order in your choice of 14k or 18k yellow gold, white gold, rose gold, or platinum. Each ring begins with a certified lab grown diamond, selected for exceptional cut, colour, and clarity — then set into a design that honours the shape's dramatic, elongated form.

The marquise's brilliant-cut facets deliver strong sparkle and fire, while its narrow profile creates a flattering, finger-lengthening effect that few other shapes can match. Of all the standard diamond cuts, the marquise typically offers the largest face-up appearance per carat — meaning it carries its weight with real visual authority.

Our marquise collection includes solitaire, halo, cathedral, and bezel settings, among others. You can also choose from a range of intricate design elements to further customise your ring — such as adding a hidden halo, a pavé bridge, a pavé band, and more. The marquise also lends itself beautifully to east-west settings, where the stone is rotated horizontally across the finger for a distinctly modern, unconventional look.

Every piece arrives with a lifetime warranty, complimentary ring resizing, complimentary engraving, and complimentary express insured shipping. If you would like guidance choosing the right marquise diamond or setting, our team is here — book a virtual consultation or begin your bespoke journey to design something entirely your own.

Frequently Asked Questions

What makes the marquise cut unique among diamond shapes?

The marquise cut is defined by its elongated body and two symmetrical pointed ends — a silhouette that no other standard diamond shape shares. Its brilliant-cut facets deliver strong sparkle, while its narrow, boat-like profile creates the largest face-up surface area per carat of any traditional cut. The result is a diamond that commands attention with both its scale and its distinctive outline.

Does a marquise diamond make the finger look longer?

Yes. The marquise's elongated proportions naturally draw the eye along the length of the finger, creating a slimming, lengthening effect. This is one of the shape's most appreciated qualities and a key reason it appeals to those looking for a diamond that flatters the hand as much as it stands out.

What settings are available for marquise engagement rings at The Jewel Concierge?

Can I design a custom marquise engagement ring?

Absolutely. Our Bespoke Journey begins with a conversation — we take the time to understand your vision, preferences, and priorities, whether you have a clear idea or are still exploring. From there, we refine the design direction together and help you select a diamond that suits your brief. Once the design is finalised, we create a detailed CAD model for you to review and approve before crafting begins. The entire process typically takes six to eight weeks from design approval, at no additional cost. You can start by filling out our Bespoke Journey order form.
