IGI report LG800622844
4.00 ct Cushion Laboratory-Grown Diamond
89/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 1.35:1 length-to-width ratio sits in the classic cushion range.
- Face-up spread (10.92 × 8.11 mm) is typical or better for a 4.00 ct cushion.
- Excellent polish and symmetry, the top finish grades.
- G color should face up white in most settings.
- VVS2 clarity: inclusions are not a practical visual factor.
What deserves a closer look
- 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.
What to check on the exact stone
- Does this cushion produce broad, chunky flashes or small needle-like crushed-ice sparkle?
- 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?
