Marquise Diamonds

Marquise cut diamonds are elongated brilliant-cut diamonds with pointed tips at both ends. The shape originates in 18th century French court jewelry and produces the largest apparent size per carat of any diamond shape due to its extreme elongation. A marquise diamond at 1 carat measures approximately 10mm x 5mm, covering substantially more finger surface than a 1 carat round at 6.5mm diameter. The pointed tips require V-prong settings to protect the vulnerable ends.

Marquise diamonds have the largest surface area per carat of all standard diamond cuts because of their extreme elongation. A 1 carat marquise appears measurably larger on the finger than a 1 carat round, oval, or cushion. This makes marquise cuts an effective choice for buyers who want maximum visual presence at a given budget.

Marquise diamonds exhibit a bow-tie effect, a dark shadow across the center of the stone caused by the viewer blocking light return through the elongated middle section. A subtle bow-tie is acceptable and common; a prominent bow-tie significantly detracts from the stone's beauty. Well-cut marquise diamonds minimize the bow-tie through precise facet angles. Because the bow-tie varies stone to stone, viewing a specific marquise in person or through high-quality video before purchase is essential.

Marquise diamonds are most frequently purchased at length-to-width ratios of 1.7 to 2.0. A ratio of 1.75 to 1.85 is widely considered the classic marquise proportion: clearly elongated and dramatic without appearing overly stretched. Ratios below 1.5 create a wider marquise that reads as less distinctly pointed and loses some of the elongation effect. Ratios above 2.0 create an extremely slender, dramatic stone that maximizes apparent size but requires careful setting to avoid fragility at the very long pointed tips.

Marquise diamonds require V-prongs at both pointed tips because the tips are the most vulnerable part of the stone and will chip under impact without protection. A typical marquise ring setting uses two V-prongs at the tips and four or six standard prongs along the sides. Bezel settings fully enclose the stone and protect the tips maximally but reduce light entry from the sides. Halo settings work well with marquise centers and provide additional structure around the elongated shape.

Marquise and oval are the two primary elongated brilliant cuts. Marquise has pointed tips at both ends and appears longer and larger per carat than oval. Oval has rounded ends and a more moderate elongation that reads as less dramatic but more universally flattering. Marquise suits buyers who want maximum apparent size and boldness. Oval suits buyers who want elongation with softer, more accessible aesthetics.

Marquise diamonds typically cost 20–30% less per carat than comparable round diamonds while appearing larger due to the elongated footprint. This combination — larger apparent size at lower per-carat cost — makes marquise an attractive value choice for buyers who want maximum visual impact. The trade-off is the bow-tie effect and the need for V-prong settings, but these considerations are manageable with proper stone selection and setting choice.

Marquise diamonds and oval diamonds are both elongated brilliant cuts, but marquise has pointed tips at both ends and greater elongation, appearing larger per carat. Oval has rounded ends and more moderate elongation with a wider range of mainstream appeal. For buyers choosing between them, marquise is the bolder, more dramatic choice; oval is the more versatile and widely appreciated choice. For the complete oval diamond range for comparison, browse oval diamonds for every oval configuration available.
