3.01 ct Marquise Laboratory-Grown Diamond

89/100 · Refined

A strong candidate on paper; confirm its light pattern in imagery.

What reads well

A 1.83:1 length-to-width ratio is outside the classic marquise range; the outline will look more compact than typical.
Slightly thick to very thick girdle: a thick girdle carries hidden weight and can reduce face-up size (thicker points are common in fancy shapes).
Screening only: for this marquise, check images or video of the exact stone for the bow-tie and whether the two points line up end to end.
Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.

Table · Ideal: At 60%, the table sits within the typical 53–63% range for a marquise, balancing brightness with fire.
Total depth · Ideal: 62.8% is within the typical 58–64% range for a marquise, keeping weight where it contributes to face-up size and light return.
Length-to-width · Favorable: A 1.83:1 outline is squarer than the classic 1.85–2.2:1 range for a marquise — a matter of taste, but worth seeing in person.
Polish · Ideal: Excellent polish is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
Symmetry · Ideal: Excellent symmetry is the top finish grade — facets are cleanly executed with nothing that would soften sparkle.
Girdle · Closer look: Slightly thick to very thick (faceted): a thick girdle carries weight in the rim, so the stone can face up a little smaller for its carat weight. It is durable, though.
Culet · Ideal: Pointed: no visible culet facet when viewed face-up.
Color · Ideal: F is in the colorless range and faces up white in any metal.
Clarity · Ideal: VVS2: inclusions, if any, are only visible under magnification.
Fluorescence · Ideal: None: no meaningful effect on appearance.

In a face-up video, does the bow-tie flicker as the stone tilts, or stay a fixed dark band across the center?
Will the ring setting use protective V-tip prongs or a bezel to safeguard the two delicate points?
Is extra carat weight trapped in the thick girdle rim where it does not add finger presence?
Can you show me the inscribed report number under a loupe before it is set?
