Marquise Engagement Rings

The Marquise Cut

Marquise Engagement Rings

A marquise diamond is an elongated brilliant with a point at each end, the shape with the largest face up size per carat of any diamond cut. A 1 carat marquise is about 10 millimeters long, against 6.5 for a round, and it makes the finger look longer and slimmer than any other shape. It is a vintage cut that has come back as a modern one, and every marquise engagement ring here is made to order in our Los Angeles atelier with both points held by prongs.

The marquise is the most demanding shape to cut well. Both points must sit on the same center line, the two halves must mirror each other, and the bow tie across the middle must be faint. When all three are right it is the most elegant diamond on a hand. When one is wrong it shows, and the certificate will not tell you.

Two ways to own one

Build your ring. Choose a setting below, then pair it with a natural or lab diamond from our inventory. A ROSI™ Score Report, our gemological intelligence, reads the cut performance and fair market position of any natural diamond you are considering, and John Anderson, our Lead Gemologist, reviews the shortlist with you.

Choose a Select ring. The Select rings arrive complete, with an IGI certified lab diamond already matched to the setting in the carat weight you choose.

How to choose a marquise diamond

• Ratio. 1.75 to 2.15 is the classic marquise. 1.85 to 2.00 is the most requested. Lower reads fuller; higher reads needle thin.
• Symmetry. Both points on the center line and the two halves mirrored. The certificate does not grade this; our gemologist checks every marquise.
• Bow tie. Marquises carry the strongest bow tie of any shape. Faint and moving is normal; dark and fixed is a cut flaw. The ROSI™ report flags it.
• Color. Color concentrates at the points. H or better in white metal; yellow gold forgives down to J and is the classic vintage pairing for a marquise.
• Setting. Prongs on both points, always. Six prongs with two at the points and four at the sides is the standard. East west, with the marquise set sideways on the band, is the modern alternative.

The marquise is the shape where the gap between a good diamond and a bad one is widest and least visible on paper. John Anderson, our Lead Gemologist, walks you through it on the phone or by video. Call 1-800-779-1726 or request a consultation. There is no charge and no obligation.
