A ratio somewhere close to 2:1 is generally regarded as the classic marquise proportion, giving the stone its signature elongated drama. Drop that ratio and the shape reads fuller and rounder; push it higher, and the silhouette stretches into something slimmer and more striking. Neither is right or wrong; it’s purely a matter of preference.
As a benchmark, a 0.38-carat, IGI-certified, Ideal cut, F color, VS1 clarity marquise shape lab grown diamond comes in around $126. This shape carries more surface area per carat than many others, so even a small jump in size can move the price more than you might expect.
VS1 & VS2 clarity sits comfortably above what a naked eye can pick up, which matters more here given how much of the stone’s interior is exposed by its open facets. Pair that clarity with a precise cut and the brilliance travels consistently down the full length of the marquise stone rather than fading anywhere along the way.
Orientation is a real styling choice with a marquise shape F color lab grown diamond. Setting the stone sideways, in what’s called an east-west mount, has become popular for showing off its width instead of its length. While sturdy prongs at both tips are non-negotiable no matter which way it’s turned, as they guarantee safety.
