The Shape with the Largest Face-Up Area

If you want your diamond to look as large as possible for your budget, the marquise cut is statistically the #1 choice in the gemological world.

Because the marquise cut is shallowly proportioned across its elongated boat-shaped ("navette") crown, it carries much less of its carat weight in the pavilion. A 1.00 carat round brilliant measures ~6.5mm, whereas a 1.00 carat marquise diamond measures approximately 10.5mm × 5.0mm. This gives the optical impression of a stone nearly double its carat weight while visually slimming and elongating the wearer's fingers.

Dual V-Prong Protection

Both pointed tips are securely wrapped with protective chevron prongs.

15% Larger Visual Spread

Appears larger face-up than an equivalent round, oval, or princess cut.

Marquise Ratio Proportion Guide

Frequently Asked Questions

Key facts and guidance about certified marquise cut lab created diamonds.

The marquise cut has the largest crown surface area of any diamond cut. Because its elongated navette shape carries less weight in its pavilion and spreads it across a long crown, a 1.00ct marquise measures ~10.5 × 5.0mm compared to ~6.5mm for a round diamond, making it look 15% to 25% larger to the naked eye.

The industry standard ratio is **1.75 to 2.15**. A ratio in this sweet spot achieves the iconic royal boat shape with curved, symmetrical wings and sharp points. Ratios below 1.70 look wide and football-like, while ratios above 2.20 look slender and needle-like.

Because the two tips come to sharp, acute points, they are the most vulnerable parts of the stone. Always select a setting equipped with **dual V-prongs (chevron prongs)** or a full bezel. The V-prongs wrap completely around each point, guarding against accidental knocks and snagging.

Direct from our Surat diamond factory, a certified 2 carat marquise cut lab grown diamond (D-F Color, VVS/VS Clarity) costs between $720 and $1,050 USD. In US retail jewelry stores, the same diamond costs $3,000 to $4,200 USD, and a mined counterpart costs $18,000+.

A **North-South setting** positions the diamond vertically along the finger, creating maximum finger elongation and a classic look. An **East-West setting** positions the diamond horizontally across the finger, creating a bold, modern, fashion-forward look that stacks well with wedding bands.
