Collection: Marquise Cut Engagement Rings

The classic range is 1.75 to 2.25, with 2.0 being the most traditional proportion. Ratios closer to 1.75 produce a stubbier, wider shape that looks less elongated. Ratios closer to 2.25 or above create a very narrow, dramatic silhouette. The right ratio depends on the size of the stone and the width of the finger. On a narrower finger, a ratio around 1.85 to 2.0 tends to look balanced. On a wider finger, ratios above 2.0 can create a more flattering lengthening effect. There is no objectively correct answer, so seeing several ratios side by side is the most reliable way to decide.

The pointed ends are more vulnerable than the curved sides, but the risk is manageable with the right setting. V-prongs or bezel tips at both points protect the ends from impact. Once properly set, a marquise diamond is no more fragile than any other shape during normal daily wear. The concern is primarily during setting and unsetting, when the points are exposed. If you're buying a marquise ring, check that the points are adequately protected and that the prongs or bezels are in good condition.

The bow-tie is a dark shadow that appears across the center of the stone when viewed face-up, shaped roughly like a bow tie. It occurs because of the way light interacts with the elongated facet pattern. Nearly all marquise diamonds show some degree of bow-tie. A faint bow-tie adds depth and visual interest. A heavy, dark bow-tie blocks light return and makes the center of the stone look dead. The severity of the bow-tie is not captured by GIA grading, so it can only be evaluated visually. Ask for photos or video of the stone taken from directly above under normal lighting to assess the bow-tie before purchasing.

Yes. East-west settings orient the marquise horizontally across the finger rather than lengthwise along it. The effect is completely different: instead of elongating the finger, the stone spans the width of the hand, creating a wider, lower-profile look. East-west marquise settings have become increasingly popular as an alternative to the traditional vertical orientation. The setting needs the same V-prong or bezel protection at the points regardless of orientation.

A contour or curved band is usually the best fit because it follows the pointed profile of the marquise without leaving a gap between the two rings. Straight bands can work if the marquise is set high enough that the band slides underneath, but with lower-profile settings a straight band will sit away from the engagement ring at the points, leaving a visible space. If you prefer a straight band, try it on with the engagement ring before committing to make sure the gap doesn't bother you. Chevron or V-shaped bands are another option that nest into the pointed end of a marquise setting.
