LAB GROWN MARQUISE CUT DIAMONDS

A marquise is a long boat shape with a point at each end. It has the largest face-up area of any cut for its weight, which means no shape shows more diamond per dollar. Grown in a lab, that arithmetic gets better again. All 12 pieces, engagement rings, solitaires and stud earrings, every one of them lab grown, in 14K or 18K white, yellow, or rose gold, or platinum, with prices ranging as low as $1,327.99

THE DETAILS

Buying a Lab Grown Marquise

The marquise shows the most stone for the money and asks the most of the setting. Both halves of that are worth understanding.

It has the largest face-up area per carat of any cut, so yes. A one carat marquise covers noticeably more finger than a one carat round, and it's the reason people pick it when the budget is fixed and the look isn't.

Both tips are the vulnerable spots and both get a V prong that covers them. Set that way, a marquise wears normally. It's still worth wearing it aware: a long stone catches on a coat pocket more easily than a round does.

Every elongated brilliant does, and a marquise shows it more than an oval because it's longer. A dark band across the middle is normal. A good cut keeps it faint, and we don't buy the stones where it takes over the face.

The classic range is 1.85 to 2.10 times as long as it is wide. Shorter than that and it stops reading as a marquise; longer and it gets narrow, the points get thinner, and that's exactly where chips happen.

Yes, and the same grading applies: same color scale, same clarity scale, same hardness, same look through a loupe. What you're saving is the difference between a grown stone and a mined one at the same specification, and on a shape this large face-up that difference buys a lot of visible diamond.

About Our Lab Grown Marquise Cut Jewelry

Nothing buys more visible diamond per carat than a marquise. It's long, it's pointed at both ends, and it makes a hand look elegant in a way no rounder shape manages. It is also the most distinctive stone on any of our shape pages, which is either the point or the problem depending on who is wearing it.

All 12 pieces, made to order in our own US factory in 14K or 18K white, yellow or rose gold, or in platinum, around the center weight you choose.

Engagement rings lead the shelf, with solitaires, a bridal set and stud earrings alongside. The stones run every one of them lab grown, and prices range as low as $1,327.99. It's a short shelf and that's the real number, not a modest one.

A marquise halo, a three stone or a heavier center is made to order and drawn in 3D first, free and with no deposit. Whatever we build carries a Lifetime Limited Labor Warranty on the setting work, ships free inside the US, and comes back within 30 days of the ship date.
