IGI report LG772622509

3.00 ct Cushion Laboratory-Grown Diamond

86/100 · Refined

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

What reads well

A 1.36:1 length-to-width ratio is outside the classic cushion range; the outline will look more elongated than typical.
The table 70% sits outside the typical cushion range.
Large culet may be visible face-up as a small dark or open point.
Screening only: for this cushion, check images or video of the exact stone for the facet pattern (bold, chunky flashes or finer "crushed ice") and any dark areas under the table.
Treatment status is not stated on the report. For a laboratory-grown diamond, ask whether it is as-grown or post-growth treated.

Table · Closer look: A 70% table is larger than typical for a cushion (56–66%). Large tables can read bright but flatter, with less fire and contrast.
Total depth · Ideal: 63.2% is within the typical 61–69% range for a cushion, keeping weight where it contributes to face-up size and light return.
Length-to-width · Favorable: A 1.36:1 outline is longer and slimmer than the classic 1–1.35:1 range for a cushion — 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 · Ideal: Medium to thick (faceted): a durable girdle thickness that doesn't hide meaningful weight.
Culet · Closer look: A large culet can show face-up as a small dark or open circle at the center.
Color · Ideal: E 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.

Does the large table look bright but flat, with less colored fire than you expected?
Does this cushion produce broad, chunky flashes or small needle-like crushed-ice sparkle?
Is the culet visible as a small dark or open point when you look straight down through the center?
Can you show me the inscribed report number under a loupe before it is set?
