IGI report LG831606277
4.00 ct Radiant Laboratory-Grown Diamond
82/100 · Considered
A balanced profile with a few questions to carry forward.
What reads well
- Face-up spread (12.32 × 7.47 mm) is typical or better for a 4.00 ct radiant.
- Table 70% and depth 64.3% fall in the typical radiant range.
- Excellent polish and symmetry, the top finish grades.
- E color is in the colorless range.
- VVS2 clarity: inclusions are not a practical visual factor.
What deserves a closer look
- A 1.65:1 length-to-width ratio is outside the classic radiant range; the outline will look more elongated than typical.
- Screening only: bow-tie, windowing and contrast in a radiant can only be judged from images or video of this exact stone.
- 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 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?
