IGI report LG787611856
2.42 ct Cushion Laboratory-Grown Diamond
90/100 · Refined
A strong candidate on paper; confirm its light pattern in imagery.
What reads well
- A 1.30:1 length-to-width ratio sits in the classic cushion range.
- Face-up spread (8.94 × 6.86 mm) is typical or better for a 2.42 ct cushion.
- Table 59% and depth 66.3% fall in the typical cushion range.
- Excellent polish and symmetry, the top finish grades.
- F color is in the colorless range.
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.
The reading, field by field
- Table · Ideal
- At 59%, the table sits within the typical 56–66% range for a cushion, balancing brightness with fire.
- Total depth · Ideal
- 66.3% 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 · Ideal
- A 1.3:1 outline is within the classic 1–1.35:1 range for a cushion.
- 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 Slightly Thick (Faceted): a durable girdle thickness that doesn't hide meaningful weight.
- 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.
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?
