IGI report LG803639543

4.00 ct Dutch Marquise Laboratory-Grown Diamond

80/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

The table 70% sits outside the typical fancy shape range.
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 fancy shape, check images or video of the exact stone for the overall light pattern, dark areas and any see-through window.
The shape "Modified Hexagonal Mixed Cut" does not match a standard profile, so a conservative general screen was used.

Table · Closer look: A 70% table is larger than typical for a fancy shape (55–65%). Large tables can read bright but flatter, with less fire and contrast.
Total depth · Ideal: 64.6% is within the typical 58–68% range for a fancy shape, keeping weight where it contributes to face-up size and light return.
Polish · Favorable: Very Good polish is a fine result; the difference from Excellent is rarely visible without magnification.
Symmetry · Favorable: Very Good symmetry is a fine result; the difference from Excellent is rarely visible without magnification.
Girdle · Closer look: Thick to very thick: 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: D is in the colorless range and faces up white in any metal.
Clarity · Favorable: VS1 is typically eye-clean.
Fluorescence · Ideal: None: no meaningful effect on appearance.

Does the large table look bright but flat, with less colored fire than you expected?
Is extra carat weight trapped in the thick girdle rim where it does not add finger presence?
Does this CVD diamond show any brown or gray undertone face-up in daylight?
Can you show me the inscribed report number under a loupe before it is set?
