3.71 ct Cut Cornered Rectangular Mixed Cut Laboratory-Grown Diamond

81/100 · Considered

A balanced profile with a few questions to carry forward.

What reads well

The table 69% sits outside the typical fancy shape range.
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.
Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.
The shape "Cut Cornered Rectangular Mixed Cut" does not match a standard profile, so a conservative general screen was used.

Table · Closer look: A 69% 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 · Closer look: 69.8% is deeper than typical for a fancy shape (58–68%). Extra depth holds weight below the girdle, so the stone can face up smaller than its carat weight suggests.
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 · Ideal: Medium: a durable girdle thickness that doesn't hide meaningful weight.
Culet · Ideal: Long: a keel-line culet, normal for elongated step and modified cuts.
Color · Ideal: D is in the colorless range and faces up white in any metal.
Clarity · Ideal: VVS1: inclusions, if any, are only visible under magnification.
Fluorescence · Ideal: None: no meaningful effect on appearance.
